Plant development is a complex process influenced by exogenous and endogenous elements. A series of postembryonic developmental events is involved to form the final architecture and contend with the changing environment. MicroRNA (miRNA) is one of endogenous non-coding RNAs, which plays an important role in plant developmental regulation. In this review, we summarized 34 miRNA families that are closely associated with plant development. Among these families, nine are expressed only in specific organs, whereas 20 families are expressed in at least two different organs. It is known that some miRNAs are expressed across most processes of plant growth, while some appear only at particular developmental stages or under special environmental conditions such as drought, waterlogging and short-day time. These miRNAs execute their diverse functions by regulating developmental gene expression levels, interacting with phytohormone signaling response, participating in the biogenesis of ta-siRNAs and affecting the production of miRNAs.
植物发育是一个受到外源和内源因素影响的复杂过程。一系列胚胎后发育事件参与形成最终的结构，并与不断变化的环境相抗衡。MicroRNA（miRNA）是一种内源性非编码 RNA，在植物发育调控中发挥着重要作用。在这篇综述中，我们总结了 34 个与植物发育密切相关的 miRNA 家族。其中，有 9 个家族仅在特定器官中表达，而 20 个家族至少在两种不同的器官中表达。已知一些 miRNA 跨越植物生长的大多数过程表达，而另一些则仅在特定发育阶段或特殊环境条件下（如干旱、水涝和短日照时间）表达。这些 miRNA 通过调节发育基因表达水平、与植物激素信号响应相互作用、参与 ta-siRNA 的生物发生以及影响 miRNA 的产生来执行其多样化的功能。
