硒在植物抵御胁迫中作用的研究进展

Research Advances on the Role of Selenium in Plants Resistance to Stress

硒是有益于植物生长的微量元素之一,在植物抵御生物胁迫与非生物胁迫中发挥重要作用。从硒在植物中的代谢途径出发,介绍了硒在不同环境胁迫下使植物抗逆性提升的作用机理,综述了硒在植物抵抗生物胁迫与非生物胁迫中的作用,以及硒与其他元素的交互作用,以期为未来硒在农业生态安全领域的研究及应用提供参考。

Selenium is one of the trace elements beneficial to plant growth,and plays an important role in plant resistance to biotic and abiotic stresses.Based on the metabolic pathway of selenium in plants,this paper introduced the mechanism of selenium on stress resistance in different environmental stresses,and reviewed the role of selenium in plant resistance to biotic and abiotic stress,as well as the interaction between selenium and other elements,so as to provide reference for the future research and application of selenium in the field of agro-ecological security.
