Abstract

In recent years, the importance of the endogenous plant tripeptide glutathione (GSH) has been increasingly recognized in plant-pathogen interactions due to its contribution to various signaling and defense mechanisms. In this paper the recent developments in the research for possible roles of GSH in infected plants are summarized. GSH participates not only in antioxidative and detoxification reactions but also in redox regulation of the expression of protective genes in infected cells. Several lines of evidence suggest that glutathione S-transferase (GST) isoenzymes also have an important role in plant disease resistance, but their exact functions have remained elusive.
