Study of the dynamics of potato plant response to infection with Potato virus Y (PVY). We analysed the expression of genes, connected to response to infection with real-time PCR. We analysed expression of genes related to photosynthesis, carbohydrates metabolism and defence response. We also measured the amount of the virus in inoculated and noninoculated leaves. The results showed, that the plants respond differently to the infection and that we can expect a time shift in the response on the level of gene expression. We also showed the salicylic acid plays a crucial role in plant response to infection and that the depletion in the salicylic acid leads to the development of severe disease.

Fungi can be found in all aerobic environments, where they can colonise various surfaces or habitats performing different functions, which are not completely understood. Lot of fungi are generalists, meaning they can be found in all habits, while other fungi are specialists present in restricted habitats. Unusual habitats for fungi are habitats with extreme conditions, which are expected to prevent development of mycobiota. Nevertheless, in extreme habitats, e.g. Antarctic dry valleys, high Arctic glaciers, salt flats and salterns, hypersaline microbial mats and plant trichomes, very reach mycobiota was found and described. In plant trichomes we found several new, not previously described, fungi groups. With the use of new generation sequencing methods we can reveal the composition of the mycobiota in various habitats, however the role of the fungi in the extreme habitats remains unclear.
