| 摘要: |
| 在逆境胁迫下，植物中的miRNA能够迅速表达并作用于某些与逆境相关的基因，启动植物的某些抗逆信号系统，提高植物抵御不良环境危害的能力。文章就miRNA的合成、作用机制、进化特点及其在植物对高盐和干旱等胁迫中的抗逆作用机制进行了综述，并对植物miRNA的研究发展趋势进行了展望。 |

| Abstract: |
| The plants miRNA can express fast and play the role of some genes associated with stress,to start signal system to improve resilience against adverse environmental hazards of plant capacity under stressed conditions.This paper focused on the synthesis of plant miRNA,mechanism,characteristics and evolution in plants of high salt and drought stress in the role of resilience,and the plant miRNA research and development trends of the prospect. |
