Research focus:
In my scientific research I investigate the issue of longevity of seeds of forest-forming species, which cosntitutes a global challenge in the sphere of retaining the biodiversity of ecosystems. I delve into the analysis of processes that shape seed stability ex situ, all the way to the molecular level, such as oxidative post-translation protein modifications and regulation of the redox status with the participation of nicotinamide adenine dinucleotide. I focus on differences between resistant (orthodox) seeds and (recalcitrant) seeds susceptible to desiccation to provide a multi-level characterisation of viability loss. I study mechanisms covering protection, repair and detoxification of seeds, shaped at the stages of maturing, drying, germination and seedling formation. I also attempt to explore new compounds, discover new interactions and biochemical processes allowing me to explain the heterogeneity of seed longevity in various tree species.

Keywords:
carbonylation, methionine sulfoxide, redox status, dehydrins, heat shock proteins, chloroplasts, photosynthesis
