超氧化物歧化酶在植物响应干旱、盐碱和冷害中的作用OA北大核心CSTPCD
Roles of Superoxide Dismutase in Plant Response to Drought,Salinity and Cold Stress
超氧化物歧化酶(SOD)在植物细胞中广泛存在,主要分为Mn-SOD,Fe-SOD以及Cu/Zn-SOD 3大类,它们可以在细胞中发挥不同的防御作用,增强植物的耐受力.此外在蓝细胞和海洋生物中存在的Ni-SOD有待探究.该研究根据SOD所包含金属离子的不同对其理化性质和作用机制进行分析;阐述了在干旱、盐碱、冷害等胁迫下SOD在植物中发挥的作用,并对该酶在未来植物生长发育进程中的作用进行展望,为有关逆境环境下植物生长发育机制的研究提供参考.
Superoxide dismutase(SOD)widely presents in plants and can be mainly classified into three categories:Mn-SOD,Fe-SOD and Cu/Zn-SOD.They play different defense roles in cells and enhance plant tolerance.Additionally,Ni-SOD in blue cells and marine organisms remains to be explored.In this paper,the physicochemical properties and mechanisms of action of SOD were analyzed according to the different metal ions contained in SOD,and the role of SOD in plants under stress conditions such as drought,salinity and cold were elucidated,and the role of SOD in plant growth and development in future was prospected,and a reference for studying the mechanisms of plant growth and development under adverse environments was provided.
