Trx 系统作为redox调节因子在植物生长发育过程和氧化还原调节和抗氧化防御中起重要作用。本项目针对加工番茄生产中两个关键问题即光合效率和抗逆性/适应性,通过研究盐胁迫条件下不同抗性基因型番茄Trx系统的响应和ROS、redox信号元件的动态变化；探讨Trx系统对细胞redox状态的平衡机制及与光合碳同化和抗性的关系；研究Trx系统外源调控因子（Se、ABA和NO）活化RCA等光合作用限制因子和提高抗性基因表达的作用机制，揭示Trx系统对番茄光合碳同化和抗盐性/盐适应性的调控机制。研究可为提高番茄抗性及产量建立一条新途径和提供可行性措施，以实现番茄的高产稳产。

Trx system as redox regulation factor play an important role in plant growth and development, redox regulation and antioxidant defense. This project , aiming at two key problems in processing tomato production namely photosynthetic efficiency and resistance/adaptability, focus on the study on Trx system response and the dynamic change of ROS, redox signaling components of two genotype tomato with different salt torlerance under salt stress, the Investigation of regulation mechanism of Trx system on cellular redox statuas and the relationship between Trx system with the photosynthetic carbon assimilation and salt resistance, the Study on the mechanism of exogenous regulatory factors of Trx system ,such as Se, ABA and NO, activating photosynthesis restriction factor of RCA and improving of resistance gene expression, in order to reveal the regulatory mechanism of Trx system on photosynthetic carbon assimilation and salt resistance/salt adaptability of processing tomato. These research results will help to set up a new way and to provide feasible measures in future to improve stress tolerance and realize high and stable yield of processing tomato.
