MicroRNAs (miRNAs) are post-transcriptional regulators of growth and development in both plants and animals. Flowering is critical for the reproduction of angiosperms. Flower development entails the transition from vegetative growth to reproductive growth, floral organ initiation, and the development of floral organs. These developmental processes are genetically regulated by miRNAs, which participate in complex genetic networks of flower development. A survey of the literature shows that miRNAs, their specific targets, and the regulatory programs in which they participate are conserved throughout the plant kingdom. This review summarizes the role of miRNAs and their targets in the regulation of gene expression during the floral developmental phase, which includes the floral transition stage, followed by floral patterning, and then the development of floral organs. The conservation patterns observed in each component of the miRNA regulatory system suggest that these miRNAs play important roles in the evolution of flower development.
微小 RNA（miRNAs）是动植物生长和发育的转录后调控因子。开花对被子植物的繁殖至关重要。花的发育需要从营养生长到生殖生长、花器官的起始和花器官的发育的转变。这些发育过程受 miRNA 的遗传调控，它们参与花发育的复杂遗传网络。文献综述表明，miRNAs 及其特定靶标以及它们参与的调控程序在整个植物界都是保守的。本综述总结了 miRNAs 及其靶标在花发育阶段基因表达调控中的作用，包括花转变阶段、花模式形成阶段，然后是花器官的发育。在 miRNA 调控系统的每个组成部分中观察到的保守模式表明，这些 miRNAs 在花发育进化中起着重要作用。
