Abstract
Plant growth regulators jasmonates, including jasmonic acid, are important regulators of plant growth and development. In the present project we study the relation between morphological and histological changes, caused by exogenously applied jasmonic acid, and some metabolic processes such as metabolism of plant hormones, photosyntehic pigments and proteins.
Recently the involvement of jasmonates in the plant defense to pathogens was indicated. The aim of present research is to investigate the role of jasmonic acid in interaction between virus and host plant. We study some physiological processes that occure as responses of potato plants to the infection with a very aggressive strain of potato virus Y (PVYNTNSLO), which causes a sever potato tuber necrotic disease (PTNRD). We already reported that the virus infection affects the metabolism of plant growth regulators cytokinins and jasmonic acid, and the metabolism of photosynthetic pigments. The changes of endogenous cytokinins and jasmonic acid might contribute to the increased tolerance in sensitive potato variety when they are grown in vitro.
