| Outline of Final Research Achievements |
Signaling networks coordinate chloroplast and nuclear gene expression in plant cells. The plastid-nuclear communication is very likely to play important roles in not only plastid differentiation, but also biotic and abiotic stress responses. In this study, we aimed to reveal the role of the plastid-nuclear communications in plant immunity and Ca2+ signaling. We demonstrated that the immune defense response is largely dependent on photosynthetic electron transfer chain activities in plant cells and that chloroplast Ca2+-binding protein CAS is involved in the regulation of plastid-encoded gene expression in plant immune responses. We also examined Ca2+ transients in plastids in response to biotic and abiotic stresses. Furthermore, we studied mechanical stimuli-induced immune defense gene expression, evolution of small GTPases in plastids and mitochondria, and evolution of psbD light-responsive promoter in plastids.
