油菜素甾醇类化合物对水稻抗逆的作用及其机制研究进展

Research Progress on Effect of Brassinosteroids Applied on Rice Stress Tolerance and Its Mechanisms

油菜素甾醇类化合物(BRs)是一类新型植物激素,对缓解水稻生产中的多种胁迫有重要作用。综述了BRs在水稻生物胁迫与非生物胁迫中作用的研究状况;从内源激素、抗氧化系统、光合作用等方面分析了其缓解各种胁迫的生理机制,以为BRs在水稻抗逆方面的进一步研究及应用提供参考。

Brassinosterols(BRs)are a class of new plant hormones and play an important role in alleviating various stresses in rice production.In order to provide reference for further research on BRs in rice stress resistance and better application in rice production in the future,the role of BRs in biological and abiotic stresses of rice was reviewed,and the possible mechanisms involved multiple perspectives,such as endogenous hormones,antioxidant system,photosynthesis,were demonstrated.
