An ingenious strategy for plant survival : Degradation of chloroplast proteins via autophagy and RCB vesicles

我们研究了作为植物生存策略的自噬降解叶绿体蛋白的机制和生理功能。结果表明：(1)含有叶绿体基质蛋白的RCB的产生依赖于自噬；(2)RCB的产生与叶片的碳状况密切相关；(3)自噬通过控制水杨酸信号和活性氧的产生来负向调节叶片的衰老。

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.
