KEW – Uchovanie endemickej flóry Karpát
Conserving the endemic flora of the Carpathian region
Program: Iné
Zodpovedný riešiteľ: Ing. Kučera Jaromír PhD.
Annotation: This project cover seed collecting and research activities of vascular plants in Carpathian region with special focus on Carpathian endemics, sub-endemics, and regional endangered species found at the edge of their distribution. In 2017 was developed Carpathians research network which connecting experts from five different countries. Project is managed by our Institution and finnaced by RGB Kew. The main aims of the project are: ex situ conservation of seeds – seed banking; comprehensive biosystematic investigation of selected Carpathian endemic taxa and taxa groups (we selected five different model genera which include Carpathian endemics – Carex curvula agg., D. arbuscula Čelak. and D. petraea Leyb., Soldanella L.: sect. Soldanella, Draba L.: sect. Aizopsis, sect. Chrysodraba and sect. Leucodraba, Silene zawadzkii Herbich); and developing a detailed distribution database for the entire endemic flora of the Carpathians and publishing the Flora Endemica Carpatica monograph.

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
Program: VEGA
Zodpovedný riešiteľ: 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.

POLYPLOID – Pôvod polyploidných komplexov: úloha polyploidizácie a geografickej a ekologickej izolácie
The origin of polyploid complexes: the role of polyploidization, geographical and ecological isolation
Program: APVV
Zodpovedný riešiteľ: 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.

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
Program: VEGA
Zodpovedný riešiteľ: 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.
