COST ETN – Európska sieť na sledovanie akvatických živočíchov
The European Aquatic Animal Tracking Network
Project registration number:
Program: COST
Project leader: Mgr. Pekárik Ladislav PhD.
Annotation: Telemetry is a commonly applied method to investigate the ecology and movement behaviour of aquatic species in relation to their environment. It provides a scientific basis for management and conservation and has significantly improved our understanding of ecosystem functioning and dynamics. More specifically, telemetry provides valuable data that can be used in many policies and directives. As a result, large scale nationally and regionally managed initiatives were implemented around the globe in recent years. Although there is a large and growing number of researchers in Europe using biotelemetry to study aquatic animals and answer management-related questions, there is a stringent lack of in-field telemetry collaborations in Europe. This situation represents a substantial loss of opportunities for: scientific excellence, funding opportunities and competitivity of European SME on the international biotelemetry market. With this COST Action, we want to close this gap and the overarching objective is to ensure a transition from a loosely-coordinated set of existing regional telemetry initiatives to a sustainable, efficient, and integrated pan-European biotelemetry network embedded in the international context of already existing initiatives. This will be achieved through working group meetings, workshops, training courses and scientific missions focused on: 1) Implementing a centralised European database, requirements and policy mapped to the data standards of existing international biotelemetry data systems, 2) improve the usefulness and inter-applicability of currently available technology and foster technological advancements, 3) promoting the establishment of key telemetry infrastructure and research on key species, and 4) provide continuous training opportunities and disseminate knowledge to the stakeholders\’ community.

Genome editing in plants – a technology with transformative potential
Editovanie genómu rastlín – technológia s transformatívnym potenciálom
Project registration number: COST CA18111
Program: COST
Project leader: Ing. Jopčík Martin PhD.
Annotation: A great challenge of this century is to provide adequate nutrition for an increasing global population while developing a more socially, economically and environmentally sustainable agriculture that counters climate change, biodiversity loss and degradation of arable land. Plant research and breeding are very important in meeting this challenge. Building on scientific progress, a number of genome editing techniques have been developed over the past two decades allowing an unprecedented level of precision in our control over genetic material and its corresponding traits.This COST Action will bring together expertise from a range of disciplines to evaluate plant genome editing techniques and their resulting products from various perspectives. The findings will serve to design a roadmap for directing and facilitating applications of genome editing in plant research and breeding, which in turn will help setting R&D priorities and stimulating further cross-national and cross-disciplinary collaborations.

SOURDOmiCS – Network biotechnológie kvasných procesov smerom k novým, zdravším a udržateľným potravinám a bioprocesom
SOURDOugh biotechnology network towards novel, healthier and sustainable food and bioprocesses
Project registration number: COST CA18101
Program: COST
Project leader: Ing. Hricová Andrea PhD.
Annotation: Traditional sourdough bread resorts to spontaneous fermentations leading to natural selections of microorganisms, mainly yeasts and lactic acid bacteria. Such microorganisms are essentially beneficial to humans and, concomitantly, inhibits propagation of undesirable microbiota. Sourdough fermentation was probably one of the first microbial processes employed by Man for food production and preservation. Sourdough bread stills widely manufactured at farm level across Europe and worldwide and is highly appreciated by consumers for its distinct flavour, texture and healthy attributes. Through a bottom-up approach, this COST Action network brings together a multidisciplinary group of scientists and SMEs/LEs dedicated for many decades to study cereals and sourdough technologies. In upstream, it aims at exploitation autochthonous (pseudo)cereals with good baking, nutritional and healthy attributes, while promoting a sustainable agriculture and preserving genetic diversity. Simultaneously, aims at contributing to develop new business opportunities to local farmers through their engagement into food processing with shared small-scale breadmaking facilities, and the integration into industrial and trade chains. Such features are in agreement with European Agenda for Food and Environment. In downstream, the biotechnological sourdough fermentation exploitation comprises several objectives: design starter cultures with a wide range of biotechnological applications; production of healthy and tasty varieties of bread, thus catalysing changes in consumers\’ diets and market orientations; production of high-added value metabolites resorting to sourdough microbiota; and valorisation of by-products from cereal production and sourdough technologies.

G-BIKE – Poznanie genómovej biodiverzity pre odolné ekosystémy
Genomic biodiversity knowledge for resilient ecosystems
Project registration number: COST CA18134
Program: COST
Project leader: RNDr. Čiampor Fedor PhD.
Annotation: In a rapidly changing environment the resilience of ecosystems depends ultimately on species adaptability. G-BIKE will enable standard and routine tools for assessing, monitoring and managing the genetic resilience and related adaptive potential of wild and captive populations. Although genetic data can be obtained for most organisms, the standardization of protocols for detecting and monitoring species’ genetic diversity, and their potential for adaptation, is still lacking. G-BIKE will assist scientists and practitioners across the EU and particularly in COST Inclusiveness Target Countries to integrate genetic and evolutionary knowledge into conservation planning policies, and to promote cross-border management and long term monitoring programs of evolutionary potential in order to ensure persistence of populations and species, and ultimately the continued supply of nature-based ecosystem services. Considering the drastic impacts of climate change during the coming decades, G-BIKE is especially urgent. The following aims will be accomplished by involving a balanced representation of scientists and practitioners from a diversity of countries: 1) clearly articulating for managers how genetic diversity can support ecosystems; 2) developing and testing best practice protocols for monitoring genetic diversity in time and space; 3) providing an online forum on emerging tools; 4) connecting all stakeholders through networking and training opportunities; 4) building a network of conservation genetics labs; 5) building a foundation for long term impact.

Biosystematika, fylogenetické vzťahy a distribúcia vreckatých húb z radu Leotiales v Karpatoch
Biosystematics, fylogeny and distribution of ascomycetes of the order Leotiales in the Carpathians
Project registration number: VEGA 2/0061/19
Program: VEGA
Project leader: Mgr. Kučera Viktor PhD.
Annotation: Most members of the order Leotiales are quite rare and are endangered almost in all countries of their occurrence. The order includes two families, Geoglossaceae (8 genera) and Leotiaceae (3 genera). They occur in some forest areas but predominantly they are associated with specific non-forest habitats, such as peat bogs, meadows, pastures and also sand dunes. Recently numerous new taxa are being described but no determination manual for their identification is available. Latest estimate includes about 25 taxa of the order in the Carpathians but delimitation of most of them is vague. We have identified serious taxonomical problems in genera Geoglossum, Microglossum and Thuemenidium that have to be solved. Taxonomical data will support consequent phylogenetic analyses and discussion on paraphyletic origin of genera. Field collections from the Carpathians, type and other material held in fungaria also published records will allow us to summarize ecology, construct distribution maps and propose threat status.

Determination, spreading pattern and impact of invasive plants on native ecosystems: case studies on Centaurea, Fallopia and Solidago
Project registration number: VEGA 2/0024/19
Program: VEGA
Project leader: RNDr. Skokanová Katarína PhD.
Annotation: The project aims to study taxonomically problematic and hardly distinguishable invasive taxa and cytotypes of Centaurea stoebe agg., Fallopia japonica agg. and Solidago canadensis agg. occurring in central Europe. By combination of biosystematic approaches (morphometrics, flow cytometry, chromosome counting) we will determine particular taxa and cytotypes. Thanks to extensive field survey and revision of herbarium specimens we will contribute to the knowledge on current and past distribution of F. japonica agg. and S. canadensis agg. in central Europe and cytotypes of C. stoebe agg. in mixed-ploidy populations. Further, we will analyse ecological demands of particular taxa and cytotypes and model their future potential spreading within the studied area. To reveal and to compare impact of invasive taxa of F. japonica agg. and S. canadensis agg. on natural biotopes we will use a combined approach including analyses of soil properties, seed bank, diversity of plants, fungi and molluscs in invaded biotopes.

Diverzita a disperzia v metapopuláciách a metaspoločenstvách malých vodných biotopov
Diversity and dispersal in metapopulations and metacommunities of small aquatic biotopes
Project registration number: VEGA 2/0030/17
Program: VEGA
Project leader: RNDr. Čiamporová – Zaťovičová Zuzana PhD.
Annotation: Project is aimed at small aquatic biotopes, very important regarding their biodiversity, yet often overlooked and understudied. Project is logically linked to previous projects of team members. Proposed is reasonable improvement of datasets on communities of natural biotopes in lowland and mountain regions, new data will be acquired on human impacted areas, including robust environmental data. Macrophytes, molluscs, zooplankton and aquatic insects were chosen as model groups due to their indication value, different ecological requirements and function in food webs. Main goal is to understand patterns of biological diversity of small water bodies, emphasizing 1) evaluation of the importance of different biotope types for biodiversity preservation, 2) assessment of dispersal and habitat features roles in metacommunity structure and 3) describing extent of connectivity within metapopulations. Reaching the goals will improve effective conservation of aquatic ecosystems – important component of global environment.

DD ChangE – Diverzita a distribúcia druhov a spoločenstiev v meniacom sa prostredí
Diversity and distribution of species and communities in changing environment
Project registration number: VEGA 2/0119/19
Program: VEGA
Project leader: Mgr. Šibíková Mária PhD.
Annotation: Spatio-temporal changes translate to changes in diversity and distribution of populations and communities across all organizational levels, influencing many aspects of biota. Shifts in distribution of plant communities and species including invasions by alien species gained significance in past decades when this phenomenon became more evident. Now it is obvious that the main drivers and causes of changes in diversity and distribution include 1) land use and management; 2) climate change; 3) spreading of alien species and 4) natural disturbances. Combinations of these factors influence vegetation, agroecosystems and forestry either in negative or positive way. Identifying general pattern at local scales, in various habitats, and differentiation of effects caused by each driver will help us to understand the impact of observed changes and their role in ecosystems. To reach our goals we focus on habitats from the basins to the alpine belt – floodplains, montane forests, grassland and alpine communities.

Diverzita rastlín jelšových lesov hlavných bioregiónov strednej Európy
Diversity of plant understory of alder forests in the main bioregions of Central Europe
Project registration number: VEGA 2/0016/19
Program: APVV
Project leader: Ing. Hrivnák Richard PhD.
Annotation: Alder forests with dominance of Alnus glutinosa are ecologically and floristically specific vegetation type. These forests belong to the endangered vegetation and they are under strong human pressure in Central Europe. We focus on the study of plant diversity patterns (alpha, beta and gamma) in the main Central European bioregions (Alpine, Continental and Pannonian) with respect to various plant groups (vascular plants, bryophytes, native and alien species) and two types of these forests, riparian alder forests and alder carrs. In addition, we would like to detect which ecological factors (including human impact) have an impact on alpha diversity of plants and which conditions predeterminate the highest species richness.

Dynamika antropicky ovplyvnených biotopov nelesnej vegetácie v procese ekologickej obnovy
Dynamics of human-altered non-forest habitats in the process of ecological restoration
Project registration number: VEGA 2/0040/17
Program: VEGA
Project leader: Mgr. Škodová Iveta PhD.
Annotation: Many semi-natural grasslands in the whole Europe are in unfavourable conservation status due to succession changes induced by land abandonment. Project aims to test various management treatments in the ecological restoration of semi-dry, mesic and fen grasslands and to set the conditions for their application. It also tries to test new methods for the elimination of expansive grass species in various ecological conditions. It is also focused on the evaluation of changes after a large-scale restoration. Among the project goals there is also monitoring of temporal dynamics and vegetation changes in anthropogenic non-forest habitats to estimate future trends in grassland vegetation. Project is logically related to several past projects focused on grassland vegetation in Slovakia (SK0115, VEGA 0181/09, VEGA 0099/13), when the network of field experiments was established to study relation between management and species composition (vegetation diversity).

ROLOFSYTS – Funkčná analýza synaptotagmínov so zreteľom na odpovede rastlín na environmentálne stresy
Functional analysis of synaptotagmins in responses of plants to environmental stresses
Project registration number: APVV-16-0398
Program: APVV
Project leader: Doc. RNDr. Jásik Ján DrSc.
Annotation: Crop yields are largely dependent on their tolerances to environmental influences, including salinity. Previously, we have shown that the Arabidopsis synaptotagmin 1 (AtSYT1), the most abundantly expressed Arabidopsis ortholog of the well-known calcium sensors in animal neurons, is involved in responses to abiotic stresses. The general goal of this proposal is to reveal the mechanisms by which AtSYTs regulate the reactions to high salinity and other stresses. We wish to characterize AtSYTs expression, describe phenotype of Atsyts mutant lines, to study subcellular localisation of AtSYTs, and to monitor intracellular dynamics of AtSYT1. Additionally, we shall address the functional analysis of the interaction fished out in the yeast two hybrid assay connecting AtSYT1 to the MAPK cascade. Our study will contribute to the overall understanding of how membrane trafficking is involved in stress responses.

Hybridné roje borovice lesnej a borovice horskej-kosodreviny na Slovensku
Hybrid swarms of Scots pine and mountain dwarf pine in Slovakia
Project registration number: VEGA 2/0063/17
Program: VEGA
Project leader: RNDr. Kormuťák Andrej DrSc.
Annotation: The project is oriented towards experimental verification of hybridological relationship between Scots pine (Pinus sylvestris L.) and mountain dwarf pine (P. mugo Turra). Within putative hybrid swarms of these species in northern Slovakia, the extent of introgressive hybridization with the parental species mentiontd above will be determined. Except for the classical approaches of artificial hybridization, the chloroplast DNA (cpDNA) is expected to be used in verification of both the interspecific and intraspecific hybrids of these pines. The degree of genetic divergence between hybrid swarms and natural populations of both parental species will be determined using cpDNA and mitochondrial DNA (mtDNA) markers. The project aims in validation of the hybrid nature of the putative hybrid swarms on the localities in Zuberec – Medzi Bormi, Suchá Hora and Terchová – Sokolie all of which are taken for rare endemites on our territory.

dyNatura2000sat – Identifikácia a monitoring biotopov Natura 2000 pomocou dynamickej segmentácie satelitných obrazov
Identification and monitoring Natura 2000 habitats by dynamic segmentation of satellite images
Project registration number: APVV-16-0431
Program: APVV
Project leader: RNDr. Šibík Jozef PhD.
Annotation: Project aims to build novel botanical, environmental, mathematical and computational methods for determining exact localization and classification of Natura 2000 habitats and for monitoring their dynamics and qualitative changes by using satellite data and dedicated image processing software. The localization, classification and dynamic space-time monitoring will be based on novel methods for filtering, segmentation and tracking of Sentinel-1 synthetic aperture radar (SAR) data, Sentinel-2 multispectral imaging data and their combination. The image processing software will allow accurate localization of Natura 2000 habitat areas in static and dynamic Earth observation data up to a precision of pixel resolution. Moreover, by the developed software we will be able to monitor continuously the habitat dynamics with alarming option in case of abrupt changes in condition or fragmentation of Natura 2000 protected areas. The methods and software will be developed for localization, classification and monitoring of Natura 2000 habitats in the territory of the Slovak Republic. As the other EU member states are also required to monitor their Natura 2000 habitats, and Slovak Vegetation Database, used for development of our methods and software, is compatible with the databases used in other countries, our methods and software will fit the European Vegetation Database and will have a strong potential to be used for identification and tracking Natura 2000 habitats at least at the European level.

Interakcie oxidu dusnatého, fytohormónov a aktívnych foriem kyslíka v odpovedi koreňa jačmeňa na ťažké kovy
Nitric oxide, phytohormones and reactive oxygen species interactions in barley root responses to heavy metals
Project registration number: VEGA 2/0039/16
Program: VEGA
Project leader: RNDr. Tamás Ladislav PhD.
Annotation: Survival of terrestrial plants relies on highly coordinated signalling mechanisms to adjust their morphology and metabolism to ever-changing environment. It is well known that hormones and reactive oxygen species (ROS) play a key role in the regulation of plant stress responses. In recent years, nitric oxide (NO) signalling was implicated in the modulation of both ROS and hormonal equilibrium in different plant species under various stress conditions. Components of the same as well as the distinct signalling pathways intensively interact among themselves integrating the internal ontogenic and external signals into morphogenic and metabolic responses in order to maximize survivability also under extreme conditions. In order to gain more insight into the role of NO in the interaction of hormones and ROS, the aim of the present project is the analysis of potential relationships between NO, ROS and hormones in the regulation of heavy metal-induced responses in barley root tip.

Mäsožravé rastliny – perspektívny zdroj génov pre hydrolytické enzýmy s antifungálnym potenciálom
Carnivorous plants – prospective source of genes for hydrolytic enzymes with antifungal potential
Project registration number: VEGA 2/0075/17
Program: VEGA
Project leader: Ing. Libantová Jana CSc.
Annotation: Chitinases play a role in the development and physiology of plants and in stress responses. The model object of this project is a carnivorous plant, Drosera rotundifolia L., from which the gene for chitinase (DrChit) involved in digestive processes of prey was isolated. As chitinous cell wall of fungal pathogens is also degraded by chitinases that are expressed during the plant defense, the DrChit has a potential use in biotechnology aimed at the plant resistance reinforcement. Here we focus on the isolation and purification of DrChit protein, its biochemical characterization and antifungal potential determination. Next, we will isolate and characterize the other genes with the carnivorous expression profile. To clarify the role of chitinases in defense, the chitinase expression profiles in embryogenic cultures of conifers exposed to abiotic stress will be evaluated as well. We suppose these results may contribute to the development of strategies for plant resistance to stress by genetic engineering approach.

PlantCalp – Mechanizmus pozičnej signalizácie v rastlinách – pochopenie DEK1 dráhy
The mechanism of positional signalling in plants – understanding of the DEK1 pathway
Project registration number: APVV-17-0570
Program: APVV
Project leader: Doc. RNDr. Jásik Ján DrSc.
Annotation: Positional signalling plays instrumental role during plant growth and development. Positional cues control what type of cell will form (cell fate determination) and how big the cell will grow (cell expansion). Genetic studies identified membrane-anchored calpain protease DEFECTIVE KERNEL 1 (DEK1) as an essential regulator of plant growth and development. Our hypothesis is that DEK1 evolved both sensory and effector functions to control robust morphogenetic outputs such as cell expansion, asymmetric cell division and cell fate determination in response to local positional cues. The exact mechanism of DEK1 activation and signal transmission is unknown. Another crucial missing piece in our understanding of DEK1-mediated signaling is the identity of DEK1 molecular targets. In this project we aim to validate putative DEK1 substrate(s) and interacting partners, functionally characterize the role of phosphorylation in DEK1 activation and continue our efforts to solve the DEK1 3D structure. The project builds on published and recent unpublished work of the principal investigator and his collaborators. Unraveling the mechanism of DEK1 action will shed light on one of the key principles of developmental control in plants with broad implications for biotechnology and agriculture.

Mikropropagácia a kryoprezervácia menej známych druhov drobného ovocia
Micropropagation and cryopreservation of less known small fruit species
Project registration number: VEGA 2/0052/17
Program: VEGA
Project leader: RNDr. Gajdošová Alena CSc.
Annotation: Berry fruits are characterized by high nutritional value and are considered as nutraceutical food. In spite of the increasing demand for berry fruits on the market their cultivation is not spread in Slovakia because of the lack of planting material of wider cultivar assortment and its high price. Rapid and profitable clonal propagation of planting material is possible to reach using tissue cultures. The project will be focused i) on elaboration of systems for micropropagation of some introduced less known small fruit species (Vaccinium, Rubus, Lonicera, Amelanchier spp.) utilizable in large-scale propagation of planting material; ii) on development of protocol for long-term storage of small fruit genetic resources by cryopreservation; iii) on testing of genetic fidelity of in vitro derived and after cryopreservation regenerated plants using molecular markers, what enables to evaluate suitability of elaborated protocols for their application for routine propagation and long-term storage of genetic resources.

Program: VEGA
Project leader: Mgr. Bérešová Anna PhD.
Annotation: Lichenization is one of the most successful fungal nutritional strategies that also enable lichens to adapt to changing ecological conditions. The aim of the project is to find out, whether symbiotic interactions play any role in shaping lichen distributional range. We focus on model lichens with Mediterranean distribution. We aim to find out whether photobiont diversity matches the so far unrecognized genetic diversity of the mycobiont across its distributional range. In particular, we will search for an evidence of photobiont switching, which can be a driver for increase in ecological plasticity of some lichen species.

Polyploidia a alopatrická diferenciácia ako mechanizmy speciácie v čeľadi Brassicaceae
Polyploidy and allopatric differentiation as speciation drivers in the Brassicaceae family
Project registration number: VEGA 2/0133/17
Program: VEGA
Project leader: RNDr. Španiel Stanislav PhD.
Annotation: In the project we will study polyploid origins, phylogenetic relationships and evolutionary history in species complexes from three Brassicaceae genera: Alyssum, Odontarrhena and Cardamine. We aim to generalize the observed patterns and elucidate major evolutionary processes that have driven diversification and speciation in these polyploid species groups. We will also revise controversial species circumscriptions and propose new taxonomic treatments. A combination of multiple methods will be used: multivariate morphometrics, flow cytometric ploidy level screening, and DNA sequencing of different target regions (including a high-throughput sequencing method). We will also develop an online karyological and nomenclatural database of the tribe Cardamineae that will help to stimulate further evolutionary studies in this group. Our studies will contribute to better understanding of plant evolution and to effective conservation of species diversity of the studied genera.

SiliToxi – Potenciál kremíka na zmiernenie toxicity arzénu a antimónu pri kultúrnych rastlinách
Potential of silicon for mitigation of arsenic and antimony toxicity in agricultural crops
Project registration number: APVV-17-0164
Program: APVV
Project leader: RNDr. Luxová Miroslava CSc.
Annotation: Contamination by arsenic (As) and antimony (Sb) is not only a serious environmental problem in highly-industrialized countries of the world, however also in Slovakia, mainly due to mining and power industry. The sites contaminated by these elements can be found across the whole Slovakia, from Malé Karpaty Mountains, Horná Nitra region, Liptov region to surrounding of Košice city in east Slovakia. As and Sb belong to toxic and dangerous elements for all living organisms. Despite an intensive research in the last years there is still only limited knowledge about the effect and phytotoxicity of As and Sb, and especially on interaction of toxic (As, Sb) and beneficial (Si) metalloids in plants what is the research aspect of this project. Therefore, the main aim of this project is to obtain a complex characterization of beneficial effects of Si on toxicity of individual elements and their combination on molecular-biological, biochemical, anatomical-morphological and physiological level. As a model object, important agricultural crops will be investigated.

POLYPLOID – Pôvod polyploidných komplexov: úloha polyploidizácie a geografickej a ekologickej izolácie
The origin of polyploid complexes: the role of polyploidization, geographical and ecological isolation
Project registration number: APVV-17-0616
Program: APVV
Project leader: prof. RNDr. Marhold Karol CSc.
Annotation: The main topics of the proposed project are microevolutionary and speciation processes in diploid-polyploid complexes belonging to the Brassicaceae family. Speciation both at the diploid and polyploid levels will be examined, elucidating the role of genome merge and duplication, geographical and ecological separation. The questions addressed have broader relevance, beyond the studied genera, and the answers can help us better understand processes underlying polyploid speciation as such. The methods applied in this project will include both conventional molecular systematics markers, as well as methods based on the Next Generation Sequencing (NGS), namely restriction site associated DNA sequencing (RAD-seq) and combination of target enrichment of low-copy nuclear genes and genome skimming (Hyb-seq). Using the multi-marker approach we expect to gain deeper insights into the studied species complexes and increased robustness of the results. As a complement, flow-cytometric, morphometric, and ecological and climatic niche analyses will be employed. In order to achieve these goals we have chosen four genera from three different tribes of the Brassicaceae family (Alysseae [Alyssum, Odontarrhena], Camelineae [Arabidopsis], Cardamineae [Cardamine]), representing different evolutionary lineages in this family. We will take the advantage of the wealth of methods that are available for and already tested in the closely related genus Arabidopsis, our previous long-term experience with the proposed study genera, and also previously collected plant material.

ATSYT3 – Systematická analýza arábkovkového SYT3 génu
Systematic analysis of the Arabidopsis SYT3 gene
Project registration number: APVV SK-CN-2017-0015
Program: APVV
Project leader: Doc. RNDr. Jásik Ján DrSc.
Annotation: Plant synaptotagmins are orthologues of the well-known calcium sensors involved in synaptic vesicle recycling in animal neurons. In our pioneering studies, we deeply characterized two fromfive members of Arabidopsis synaptotagmin family. We have shown that Arabidopsis synaptotagmin 1 (AtSYT1) participates in responses to environmental stresses through plasma membrane resealing and that a close homologue, AtSYT2 expressed in male and female gametophytes is required for pollen tube development. The general goal of our further studies is to understand the role of another Arabidopsis synaptotagmin, AtSYT3, in regulation of developmental physiological processes in Arabidopsis model organism. We wish to meet thegoals of the project by characterization of the gene expression pattern, identifying regulation mechanisms of the gene expression on different levels, deep phenotyping of atsyt3 mutant lines, studying subcellular localization of AtSYT3 protein and monitoring its traffic and turnover routes under different environmental stress conditions. Our study will contribute to the overall understanding of how membrane trafficking is involved in stress responses. This bilateral exchange visit grant help us to achieve outlined scientific goals and allow personal growth of young scientists and PhD. students at both collaborative institutions.

Systematika a fylogenéza rodu Dermoloma v Európe a Severnej Amerike
Systematics and phylogeny of the genus Dermoloma in Europe and North America
Project registration number: VEGA 2/0018/18
Program: VEGA
Project leader: Mgr. Adamčík Slavomír PhD.
Annotation: Dermoloma is insufficiently known genus of basidiomycetes classified in the order Agaricales (Agaricomycotina). More than 30 species are described worldwide, but only few of them are generally accepted. Opinions about morphological delimitation and number of the species are very variable in the current literature. Traditionally, up to eight species are recognised, although more than 30 European species were described. Our preliminary phylogenetic study suggest existence of more than 25 molecular operation units in Europe that probably represent independent species. Aim of the project is to define European and North American Dermoloma species by means of molecular and morphological methods and to assign them correct names. Fungi of the genus Dermoloma are essential part of grassland ecosystems and accordingly this project will deal with studies of environmental soil samples. We will look for suitable metabarcode for identification of species using next generation sequencing (metagenomics).

Štúdium funkcie génov dehydrínov z Arabidopsis thaliana pri tolerancii voči vybraným typom abiotického stresu
Studying of the function of dehydrin genes from Arabidopsis thaliana in the tolerance to selected types of abiotic stresses
Project registration number: VEGA 2/0035/17
Program: VEGA
Project leader: Ing. Boszorádová Eva PhD.
Annotation: Due to the changes in the environment, plants are increasingly exposed to different types of abiotic stresses such as drought, salinity, low temperature or the presence of heavy metals. A part of plant response is a modulation of the cellular metabolism and production of a wide range of proteins including dehydrins. Dehydrins are hydrophilic proteins that are induced mainly under of low temperature or dehydration. The mechanism of their action has not been clarified yet. The work is aimed to study the effect of constitutive expression of Arabidopsis dehydrin genesAt1g54410, At2g21490 and At3g50970 on the tolerance of transgenic tobacco plants against selected types of abiotic stresses, and their combinations. Their structures contain histidine-rich regions that have potential to bind free metals; therefore, it could contribute to increased tolerance to heavy metals. At the same time we will study the extent to which the overexpression of dehydrin genes interact with other components of plant defense.

PLADEFNUT – Štúdium vplyvu rôznych nutričných podmienok na akumuláciu toxických elementov v pšenici
Studying the effect of different nutritional conditions on the accumulation of toxic elements in wheat
Project registration number: APVV-15-0051
Program: APVV
Project leader: Ing. Boszorádová Eva PhD.
Annotation: The project addresses the impact of two important environmental contaminants on plants at present,namely the presence of toxic metals, excessive amounts / concentrations of nitrogen and their combinations.Both factors are the result of the development of industry, agriculture and chemical production that areassociated with a large number of pollutants, primarily sulfur oxides, nitrogen, carbon emissions and heavymetals. Knowledge about plant defense mechanisms against these factors is limited. Especially the effects ofexcessive fertilization on accumulation of metals as well as on the plants themselves are at deeper levels littlestudied. The project will address this issue comprehensively through the study of antioxidant enzymes andquantitative/qualitative changes in profiles of typical plant defense proteins. In parallel line of project we willcharacterize a set of varieties of wheat grown in Slovakia for genetic potential to accumulate cadmium usingavailable molecular markers. The project will generate new knowledge about the molecular background of plantresponses to relatively little studied types of stress. These will be evaluated for potential use as markers fortolerance /sensitivity to metal toxicity or excessive application of fertilizers. Knowledge on the effect of increasingconcentrations of nitrogen to plants and their defense capacity will be useful for the management of fertilizerapplication in agriculture. The project will also contribute to the characterization of wheat germplasm fromSlovakia in terms of potential health risk when grown on contaminated territories.

Štúdium vplyvu sekretómu na zvýšenie embryogénnej kapacity pri vybraných druhoch ihličnanov
The study of secretome influence to increasing embryogenic capacity of selected Conifer species
Project registration number: VEGA 2/0056/18
Program: VEGA
Project leader: Mgr. Klubicová Katarína PhD.
Annotation: Somatic embryogenesis represents an efficient plant regeneration system for theoretical studies as well as for mass propagation, especially in conifers. Although the process has been initiated for many conifer species, maturation of somatic embryos and somatic seedling regeneration needs deeper understanding. Advances in understanding of maturation and complete plant regeneration are necessary to use the regeneration system for conifer micropropagation. The aim of the submitted proposal is isolation and identification of a secretome of embryogenic cell lines with different embryogenic capacity using proteomic methods and to find potential markers or proteins active in regulation or signal transduction in selected conifer species and contribute to better understanding of process of somatic embryogenesis in woody plants.

Štúdium vybraných fyziologických a molekulárnych parametrov zahrnutých v regenerácii a raste parazitických burín Phelipanche spp.
Study of selected physiological and molecular factors involved in regeneration and growth of parasitic weeds of Phelipanche spp.
Project registration number: VEGA 2/0138/17
Program: VEGA
Project leader: RNDr. Matúšová Radoslava PhD.
Annotation: Parasitic plants of Phelipanche, Orobanche and Striga spp. belong to economically important plant pathogens with negative impact on agriculture. They are causing an annual loss of more then 7 billion US$. After germination these parasitic plants attach to the root system of host plants and acquire water and all nutrients from the host. There is no effective method to eliminate these weeds at present. Therefore the scientists focus their research on identification of genes and mechanisms involved in interactions between parasitic plants and their hosts. The main goal of this project is study of factors influencing growth and regeneration of Phelipanche spp. under in vitro conditions. This knowledge together with developed protocols for Phelipanche genetic transformation will allow to study functions of genes involved in parasite-host interactions and help in development of novel methods for the selective control of root parasitic weeds.

Taxonómia čeľadí Elmidae, Protelmidae a Dryopidae
Taxonomy of families Elmidae, Protelmidae and Dryopidae (Insecta: Coleoptera)
Project registration number: VEGA 1/0515/19
Program: VEGA
Project leader: RNDr. Čiampor Fedor PhD.
Annotation: Beetles of the families Elmidae, Protelmidae and Dryopidae are adapted with their morphology and physiology primarily to life in the aquatic environment. Rather exceptionally are some Dryopidae from the wet tropics terrestrial (e.g. Sostea, Geoparnus, Spalacosostea, Monstrosostea).
The biodiversity of these groups and their evolutionary history are still poorly known, despite their almost cosmopolitan distribution and great importance in eco-environmental research. This project deals with taxonomy and reconstruction of phylogeny of studied beetles by a complex molecular-morphological approach. It is focused on the systematic position of the questionable and newly described taxa, and recognition of evolutionary patterns in the phylogeny of Elmidae, Protelmidae and Dryopidae.

Program: VEGA
Project leader: RNDr. Letz Dominik Roman PhD.
Annotation: The main aim of the project is to carry out thorough taxonomic, nomenclatural and chorological revision of diversity of vascular plants of Slovakia. New checklist of taxa will be published as an important reference source not only for botanists and other fields of science dealing with vascular plants, but also for legal issues, nature conservation, agriculture and forestry. The revision will critically respect all the actual data on the flora of Slovakia as well as latest discoveries in plant phylogeny and taxonomy. The checklist will be compatible with the current Euro-Mediterranean checklist (Euro+Med PlantBase) and other international standards. Within the project, numerous nomenclature issues will be dealt with that will result also in papers published in international journals. Web portal created for the new checklist will be a single access point not only for the information on accepted plant names and synonyms, but also for the vernacular names, and other data.

Tradičné ekologické poznatky pre ochranu a obnovu travinno-bylinných biotopov
Traditional ecological knowledge for grassland conservation and restoration
Project registration number: VEGA 2/0095/19
Program: VEGA
Project leader: Mgr. Janišová Monika PhD.
Annotation: Recent crisis in biodiversity conservation of high nature value grasslands and failures of the Common Agriculture Policy of the EU ask for new effective solutions. Semi-natural grasslands evolved through a long-lasting low-intensity human land use, thus their biodiversity can be most effectively preserved by simulation of traditional agricultural practices. In the project we focus on a detail analysis of grassland phytodiversity in close relation with its historical development and traditional land use. The regions of the Eastern and Central Europe with well maintained traditional rural culture belong to the key study areas. Obtaining of high-value biological, ecological and ethnological data on the selected sites should guarantee the proper interpretation of the gathered traditional ecological knowledge. This can become a valuable scientific material for future adjustment of socio-political mechanisms in the realm of grassland conservation and restoration and sustainable land use.

Transkripčná, posttranskripčná a posttranslačná regulácia génu IRT1, rozhodujúceho transportéra železa v koreni rastlín
Transcriptional, post-transcriptional and post-translational regulation of IRT1 gene, a key transporter of iron in plant roots
Project registration number: VEGA 2/0115/17
Program: VEGA
Project leader: Doc. RNDr. Jásik Ján DrSc.
Annotation: Using transgenic and mutant lines in combination with the current genetic, molecular biological, histochemical, immunological, fluorometric, chemical analytical and microscopic methods we want to explore whether and how the presence or absence of iron and other metal elements transferred by IRT1 protein may affect the activity of IRT1 promoter, the process of RNA splicing, localization, turnover and intracellular dynamics of IRT1 protein varieties in roots of the model organism Arabidopsis thaliana. Examination of multi-level regulation of the IRT1 gene and simultaneous monitoring of the contents and the distribution of iron and other metallic components in the plants will yield valuable information for applications in biotechnology in order to enrich the plants with iron and / or to limit the absorption of potentially toxic metal elements. The findings may be useful in the agricultural breeding practice to obtain higher yielding varieties and tolerant plants to environmental stress caused by heavy metals.

Vplyv hybridizácie na diverzifikačné a speciačné procesy u Karpatských zástupcov rodu Soldanella
The impact of hybridisation on diversification and speciation processes in Carpathian members of the genus Soldanella
Project registration number: VEGA VEGA 2/0041/19
Program: VEGA
Project leader: Mgr. Slovák Marek PhD.
Annotation: The project addresses the impact of hybridization on the diversification and overall demographic structure of mountain-dwelling species of the genus Soldanella. The study design is focused on species occupying the genus diversity centre, specifically mountain regions of the Carpathians and adjacent areas (Bohemian Massif, NE Alps and east Balkan mountain ranges). To resolve proposed questions, we will employ a combination of modern methods and analytical tools including novel genomic approaches such as the RAD sequencing, karyological, cytogenetic, morphological and ecological analyses. Outcomes of the project will enable to uncover frequency and intensity of gene flow among studied taxa and specify factors and processes which have triggered or prevented hybridization (introgression) among pairs of closely and more distantly relatedspecies. We should also elucidate whether hybridisation contributed to the accumulation of novel lineages and facilitated speciation events in the genus.

Vplyv kremíka a kyseliny salicylovej na fyziologické a biochemické procesy rastlín kukurice vystavených stresu z antimónu (Sb) a niklu (Ni)
Effect of silicon and salicylic acid on physiological and metabolical processes in maize plants stressed by antimony (Sb) and nickel (Ni)
Project registration number: VEGA 2/0018/17
Program: VEGA
Project leader: RNDr. Luxová Miroslava CSc.
Annotation: The increased attention to the environmental contamination by heavy metals is paid over the last few decades. One of the potential environmental contaminants is antimony. Sb in large amounts enters the environment by anthropogenic activity. Nickel is considered as essential element that is toxic to most plants at higher concentrations. Ni is accumulated in soils mainly due to sewage sludge deposition, application of industrial compost or atmospheric fallout, near processing factories. In this project we will study the responses of maize plants stressed by Sb and Ni at the level of biomass production and at the biochemical (formation of ROS, activity of antioxidative enzymes) and physiological (membrane damage, changes in content and expression of proteins) level. We will determine whether the individual application of silicon or salicylic acid or their combination can protect maize plants from Sb or Ni toxicity by fine-tuning the antioxidative system of plants and/or improving plant growth and development.

Project registration number: APVV-16-0439
Program: APVV
Project leader: doc. RNDr. Salaj Ján DrSc.
Annotation: Effects of sulphoraphane on cencer prevention was already proven. Sulforaphane is often presents in food at the non-effective level for fulfillment the prevention effects. In addition, the natural glucosinolate form of sulforaphane, glucorafanine, is much less effective, therefore its activation to sulforaphane is needed. This conversion is catalysed by enzyme, myrosinase (EC 3.2.1.147). Aim of the current project is to design the new product based on sulforaphane-glucosinolate and stabilized myrosinase as combine product.

Annotation: The project deals with changes in biodiversity in an urban environment in two ways: in the space (ecological gradients, fragmentation of habitats) and time (historical data). For study, we chose two ecologically linked model groups: vascular plants and land snails. Based on the research of these model organisms, we will solve five main points: [1] How the urban fragmented woodland fits principles of the island biogeography and what is the impact of the fragmentation and env. variables on the biota structure and variability. [2] Whether and to what extent the genetic diversity of the populations of selected model species varies in long-term continuously forested areas comparing the neorefugia; [3] How the urban environment impacts in time and space on the diversity of indigenous species; [4] On the basis of the theory of refugia verify what is the ecol.l traits structure of biota in the remains of forest vegetation; [5] Whether biotic homogenization occurs and which groups of biota are most affected by biotic homogenisation.
