摘要
植物micro RNAs(mi RNA)是一类长度20~24 nt的内源非编码小RNA,通过互补配对原则降解或抑制m RNA,从而调控植物生命过程的相关生理活动。植物在生物胁迫和非生物胁迫下可以应激表达一些mi RNA,并作用于逆境相关靶基因,使植物在生理反映上产生对胁迫的适应性。本综述扼要阐述植物mi RNA的合成途径和作用机制,对mi RNA与植物的逆境包括非生物胁迫和非生物胁迫响应的机理及作用机制等领域进行综述,并对其在果树抗逆研究中的利用前景进行分析。
t Plant microRNA （miRNA） is a class of endogenous noncoding small RNA with the length of 20 nt-24 nt, which can degrade or inhibit mRNA through complementary pairing principle, thus regulating the related physiological activities in plant life processes. Alarge amountofplant miRNAs are induced under biotic stress and abiotic stress, which can target the stress related genes to respondto these different stresses inphysiologicaland biochemicalreaction. In this paper, the synthesis route and mechanism of action of plant miRNA were briefly described, and the mechanism of miRNA in plant stress resistanceincluding biotic stress and abiotic stress were reviewed. Also, the prospect of utilization in fruit tree resistance to stress was analyzed.
