| 蛋白质S-亚硝基化是NO与蛋白质的半胱氨酸残基共价连接形成S-亚硝基硫醇的过程.叶绿体内快速变化的氧化还原环境容易导致蛋白质S-亚硝基化修饰发生.综述了植物逆境应答过程中叶绿体蛋白质S-亚硝基化参与调节的光合电子传递、卡尔文循环、抗氧化系统、蛋白质合成、蛋白质加工与周转、Ca2+介导的信号转导、氮同化、硫同化，以及四吡咯化合物合成等途径，为全面理解植物逆境应答过程的NO调控网络机制提供了线索. |

| Abstract: |
| Protein S-nitrosylation is a NO signal transduction pathway,in which NO is covalently linked to a protein cysteine residue to form an S-nitrosothiol.The rapidly changing redox environment in the chloroplasts easily leads to protein S-nitrosylation.In this study,we reviewed that the photosynthetic electron transport,Calvin cycle,antioxidant system,protein synthesis,protein processing and turnover,Ca2+-mediated signaling,nitrogen and sulfur assimilation,as well as tetrapyrrole biosynthesis which were modulated by protein S-nitrosylation.These studies provide important clues for a comprehensive understanding of the NO signaling regulatory network in plants. |
