Auxin, primarily indole-3-acetic acid (IAA), is a versatile signal molecule that regulates many aspects of plant growth, development, and stress response. Recently, microRNAs (miRNAs), a type of short non-coding RNA, have emerged as master regulators of the auxin response pathways by affecting auxin homeostasis and perception in plants. The combination of these miRNAs and the autoregulation of the auxin signaling pathways, as well as the interaction with other hormones, creates a regulatory network that controls the level of auxin perception and signal transduction to maintain signaling homeostasis. In this review, we will detail the miRNAs involved in auxin signaling to illustrate its in planta complex regulation.

植物激素生长素（Auxin），主要是吲哚-3-乙酸（IAA），是一种多功能的信号分子，调节植物生长、发育和应激反应的许多方面。最近，microRNAs（miRNAs）作为短链非编码 RNA 的一种类型，通过影响植物中生长素的稳态和感知，成为生长素反应途径的主要调控因子。这些 miRNA 与生长素信号通路的自我调节以及与其他激素的相互作用，共同构成了一个调控网络，控制生长素感知和信号转导的水平，以维持信号稳态。在这篇综述中，我们将详细介绍参与生长素信号转导的 miRNAs，以阐明其在植物体内的复杂调控。
