摘要
miRNA是一类长度为18~24 nt的内源性非编码小RNA。在逆境胁迫下,miRNA通过与目标基因碱基互补配对,对目标基因mRNA进行剪切或翻译抑制,从而使果树响应各种逆境胁迫。本文介绍了植物miRNA的合成和作用机制,对果树miRNA在响应生物和非生物胁迫(干旱、冷害、盐胁迫、营养元素缺失)的研究进展进行了综述,并对miRNA在果树抗逆方面的研究前景进行了分析。
miRNA is a class of endogenous noncoding small RNA with the length of about 18-24 nt.Under stress conditions,miRNAs can cut or suppress the translation of target gene mRNA by regulating complementary pairing with target genes,so that the fruit trees respond to various adversity stresses.This article introduced the synthesis and mechanism of plant miRNA,and summarized the research progress of fruit tress miRNA in response to biotic and abiotic stresses(such as drought,cold damage,salt stress and nutrient deficiency).Also,the research prospect of miRNA in fruit tree resistance to stress was analyzed.
