MicroRNAs (miRNAs) are a class of non-coding single-stranded RNA molecules composed of approximately 20-24 nucleotides in plants. They play an important regulatory role in plant growth and development and as a signal in abiotic tolerance. Some abiotic stresses include drought, salt, cold, high temperature, heavy metals and nutritional elements. miRNAs affect gene expression by manipulating the cleavage, translational expression or DNA methylation of target messenger RNAs (mRNAs). This review describes the current progress in the field considering two aspects: (i) the way miRNAs are produced and regulated and (ii) the way miRNA/target genes are used in plant responses to various abiotic stresses. Studying the molecular mechanism of action of miRNAs' downstream target genes could optimize the genetic manipulation of crop growth and development conditions to provide a more theoretically optimized basis for improving crop production. MicroRNA is a novel signalling mechanism in interplant communication relating to abiotic tolerance.
微小 RNA（miRNAs）是一类非编码单链 RNA 分子，由大约 20-24 个核苷酸组成，存在于植物中。它们在植物生长发育和作为非生物胁迫信号中发挥重要的调节作用。一些非生物胁迫包括干旱、盐、冷、高温、重金属和营养元素。miRNAs 通过操纵靶信使 RNA（mRNA）的切割、翻译表达或 DNA 甲基化来影响基因表达。本综述从两个方面描述了 miRNA 领域的研究进展：（i）miRNA 的产生和调控方式；（ii）miRNA/靶基因在植物应对各种非生物胁迫中的作用方式。研究 miRNA 下游靶基因的作用分子机制，可以优化作物生长发育条件的遗传操作，为提高作物产量提供更具理论优化的基础。miRNA 是一种与非生物耐受性有关的植物间通讯的新型信号机制。
