Plant acclimation to changing environmental conditions involves the interaction of different signalling molecules, including reactive oxygen species and hormones. Redox regulation exerted by thioredoxin (TRX) and glutaredoxin (GRX), two oxidoreductases, is emerging as a specific point of control mediating signal transduction pathways associated with plant growth and stress response. Phytohormones are messengers that coordinate plant cell activities to regulate growth, defence, and productivity, although their cross-talk with components of the redox system is less known. The present review focuses on our current knowledge of the interplay that occurs between TRX and GRX systems and phytohormonal signalling pathways in connection with the control of plant development and stress responses. Here, we consider the regulation that phytohormones exert on TRX and GRX systems, as well as the involvement of these redox proteins in the control of phytohormone-mediated signalling pathways.
植物对不断变化的环境条件的适应涉及不同信号分子的相互作用，包括活性氧和激素。由硫氧还蛋白（TRX）和谷氧还蛋白（GRX）这两种氧化还原酶施加的氧化还原调节，正成为介导与植物生长和应激反应相关的信号转导途径的一个特定控制点。植物激素是协调植物细胞活动以调节生长、防御和生产力的信使，尽管它们与氧化还原系统成分的相互作用鲜为人知。本综述聚焦于我们目前对TRX和GRX系统与植物激素信号通路之间在植物发育和应激反应控制方面相互作用的认识。在这里，我们考虑植物激素对TRX和GRX系统的调节作用，以及这些氧化还原蛋白在植物激素介导的信号通路控制中的作用。
