Population growth, limited arable land and climate change threaten the foundations of our civilisation. The aim of the project is to identify key regulators enabling the integration of signal pathways for environmental factors, hormones and stress-induced factors with epigenetic regulations and to determine their role as potential targets in stress-resistant plant production. The information obtained will serve to improve the crust and potatoes targeted with the ultimate goal of obtaining crops with higher yields under stressful conditions. a.
