摘要: MicroRNA(miRNA)为长度20~24 nt的非编码小分子RNA。生物通过调节体内miRNAs的表达水平,调控其靶标基因的稳定性及翻译,从而实现对自身生长发育的调节和环境胁迫的响应。miRNAs通过不同的调控通路在水稻的产量形成及对环境胁迫响应方面发挥巨大作用。通过对miRNA在水稻增产和胁迫响应方面的相关研究进行综述,以期为水稻种质资源挖掘和品种改良提供新的研究思路。

Abstract: MicroRNA (miRNA) is a non-coding small RNA with a length of 20~24 nt. Organisms regulate autologous development and response to environmental stress through regulatory of miRNAs expression level in vivo, which affect the stability and translation of their target genes. MiRNAs play a significant role in rice yield andresponse to environmental stress through different regulatory pathways. The relevant researches on miRNA in rice yield increase and stress responsewas reviewed,in order to provide new research ideas for the exploitation of rice germplasm resources and the improvement of rice varieties.

Key words: microRNA (miRNA), rice yield, environmental tolerance, biotic responses
