MicroRNA在植物抵御盐胁迫过程中的作用

Role of MicroRNA in Plant Resistance to Salt Stress

盐胁迫是植物生长发育过程中的重要限制因子,可影响植物器官发育、形态建成、信号转导等各个环节,严重时会导致植物死亡。MicroRNA(miRNA)是一类长约19-25 nt的非编码单链RNA分子,越来越多的研究发现,在植物抵御盐胁迫过程中,miRNA可通过参与调控植物种子萌发、器官发育、形态建成、活性氧清除等过程发挥重要作用。对在植物抵御盐胁迫过程中发生响应的miRNA进行综述,旨在为植物耐盐机制研究和植物耐盐分子育种提供参考。

Salt stress is a major limiting factor in the process of plant growth and development,which can affect the process of plant organ development,morphogenesis,signal transduction,and so on. MicroRNA（miRNA）is a class of non-coding single stranded RNA about 19-25 nt long,and more and more studies have found that plant miRNAs play an important roles in salt resistance by participating in the regulation of plant seed germination,organ development,morphogenesis and active oxygen scavenging. In this paper,plant miRNAs,which respond to salt stress,are reviewed in order to provide references for the study of salt tolerance mechanism and molecular breeding of plant salt tolerance.
