Somatická embryogenéza vybraných druhov ihličnatých drevín: indukcia embryogénnych pletív, ich udržiavanie, maturácia somatických embryí a regenerácia rastlín

Annotation: Somatic embryogenesis (SE) is an in vitro process of embryo differentiation from somatic cells of a plant body. In conifers the process involves several steps as: initiation of embryogenic tissues, their maintenance, somatic embryo maturation and plantlet (somatic seedlings) regeneration. Each step requires specific conditions and is affected by several factors. The submitted proposal intends to study the individual steps of SE, mostly the effect of primary explant developmental stage, plant growth regulators influence as well as osmotic potential of the culture medium. Species as Abies alba, Pinus sylvestris and Pinus nigra will be included as experimental material.

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.

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.
