Climate change significantly impacts crop production by inducing several abiotic and biotic stresses. The increasing world population, and their food and industrial demands require focused efforts to improve crop plants to ensure sustainable food production. Among various modern biotechnological tools, microRNAs (miRNAs) are one of the fascinating tools available for crop improvement. miRNAs belong to a class of small non-coding RNAs playing crucial roles in numerous biological processes. miRNAs regulate gene expression by post-transcriptional target mRNA degradation or by translation repression. Plant miRNAs have essential roles in plant development and various biotic and abiotic stress tolerance. In this review, we provide propelling evidence from previous studies conducted around miRNAs and provide a one-stop review of progress made for breeding stress-smart future crop plants. Specifically, we provide a summary of reported miRNAs and their target genes for improvement of plant growth and development, and abiotic and biotic stress tolerance. We also highlight miRNA-mediated engineering for crop improvement and sequence-based technologies available for the identification of miRNAs associated with stress tolerance and plant developmental events.
气候变化通过诱导多种非生物和生物胁迫显著影响作物生产。世界人口的不断增加以及他们对食物和工业的需求要求我们集中精力改进作物，以确保可持续的粮食生产。在各种现代生物技术工具中，microRNAs（miRNAs）是可用于作物改良的引人注目的工具之一。miRNAs 属于一类小的非编码 RNA，在许多生物过程中发挥着关键作用。miRNAs 通过转录后靶 mRNA 降解或翻译抑制来调节基因表达。植物 miRNAs 在植物发育和各种生物和非生物胁迫耐受中具有重要作用。在这篇综述中，我们提供了以前关于 miRNAs 的研究的推进证据，并对培育未来具有抗逆能力的作物植物方面的进展进行了综述。具体来说，我们总结了报道的 miRNAs 及其靶基因，以改善植物的生长和发育以及非生物和生物胁迫耐受性。我们还强调了 miRNA 介导的作物改良工程以及用于鉴定与胁迫耐受和植物发育事件相关的 miRNAs 的基于序列的技术。
