| 摘 要： | microRNA（miRNA）是一类20~24bp的内源性小分子非编码RNA,广泛存在于真核生物中。成熟的miRNA通过与靶基因较保守的互补位点配对结合,在转录后水平负调控靶基因的表达,参与植物的生长发育、信号转导和逆境响应等过程。本文综述了植物在生物胁迫和非生物胁迫（重金属、干旱、低温、盐、热）响应中miRNA的作用及其调节机理研究进展,指出存在问题并进行展望。

| Abstract: | MicroRNA (miRNA) is a class of endogenous small molecule non-coding RNA with length about 20-24bp, which widely exists in eukaryotes. The mature miRNA is bound to complementary loci of target genes, regulates negatively the expression of target gene, and involves in plant growth and development, signal transduction and stress response. In this paper, the advanced progress about the effects and regulationary mechanisms of miRNA were reviewed under biotic stresses and abiotic stresses (including heavy metals, drought, low temperature, salt, and heat), and the problems and the research in the future are suggested. |
