About Krystyna Oracz

Actually, I am an Associate Professor in the Department of Plant Physiology, WULS-SGGW (Poland), leading the SeedExplorerGroup and managing my projects funded by grants of the National Science Centre and the Foundation for Polish Science.

For the period of my scientific career I am fully aware about the important recent advances in seed biology. In my work I elucidate the molecular mechanisms of regulation of seed germination and dormancy, with a focus on the role of Reactive Oxygen Species (ROS) and phytohormones. My results provided a novel ROS-mediated mechanism for seed dormancy alleviation and thereby opened a new field in seed biology research. This mechanism involves a change in proteome oxidation, resulting from an accumulation of ROS during after-ripening. Hence, ROS accumulation appears to be a key signal governing cell activity during after-ripening.
