Research Abstract

We studied mechanisms and physiological functions of a degradation of chloroplast proteins by autophagy as a strategy of plant survival. It was revealed that (i) tye production of RCBs which contain stromal proteins of chloroplasts is dependent on autophagy; (ii) the RCB production is closely related to leaf carbon status; (iii) autophagy negatively regulates leaf senescence by controlling salicylic acid signaling and the production of reactive oxygen species.
