Outline of Final Research Achievements

Oxidative stress is accompanied by various environmental stresses, thus signaling mechanism involved in the oxidative stress is an important subject to understand environmental stress response in plants. In this study, two possibilities of reception of oxidative stress signal were validated. As a result, involvement of interaction of HSFA1 and HSP70/90 in oxidative stress recognition was rejected. On the other hand, recognition of oxidative stress signal by GPCR-like receptor was supported by various positive data, therefore I published these results in two original papers.
