Scientists of Far Eastern Branch of the Russian Academy of Sciences (FEB RAS), Far Eastern Federal University (FEFU) and National Taiwan University comprehended state of the art scientific knowledge about plants stress response activated by unfavorable environmental factors.
Researchers proposed ways to improve crop plants stress resistance by developing one's heritable stress response memory which will allow preserving the stability of the yield obtained worldwide.
International biotechnology teams have long been taking actions to boost plants resistance to major stressors provoking crop loss like heat, cold, lack of/ excess of light, drought/excess of moisture, as well as various combinations of these factors.
However, current methods are developed with no full consideration of the stress response mechanisms based on different variants of intercellular communication in plant organisms.
Biotechnologists from FEFU, FEB RAS, and the National Taiwan University have scrutinized how the main mechanisms through which plant cells learn about the stressful situation and react to it -- abscisic acid (ABA) signal subsystems and heat shock proteins -- interact with each other.
Scientists have pointed out that SWI/SNF proteins play an important role in the interaction between these subsystems., These proteins are responsible for remodeling of chromatin, i.e.
