MicroRNAs (miRNAs) are a class of endogenous, non-coding small RNA that cleavage mRNA targets in sequence-specific manner or the inhibition of translation, which regulates gene expression at the post-transcriptional level. miRNAs are involved in the regulation of plant growth, metabolism and stress response. miR167 family is one of the highly conserved miRNA families in plants. It functions mainly by regulating the () and () genes, and participates in regulating the development of roots, stems, leaves and flowers, flowering time, embryonic development, seed development and stress response. Here, we reviewed the biological functions of miR167 family and its target genes in plant growth and development and stress response, and further discussed the application prospect of miR167 in agricultural production. Furthermore, this review provides references for the further study of miR167 family in plants.
微小 RNA（miRNAs）是一类内源性、非编码的小 RNA，通过序列特异性方式切割 mRNA 靶标或抑制翻译，从而在转录后水平调节基因表达。miRNAs 参与植物生长、代谢和应激反应的调节。miR167 家族是植物中高度保守的 miRNA 家族之一。它主要通过调节（）和（）基因的功能，参与调节根、茎、叶和花的发育、开花时间、胚胎发育、种子发育和应激反应。在这里，我们综述了 miR167 家族及其在植物生长发育和应激反应中的靶基因的生物学功能，并进一步讨论了 miR167 在农业生产中的应用前景。此外，本综述为植物中 miR167 家族的进一步研究提供了参考。
