植物DA1肽酶是一种关键的蛋白酶, 在植物的生长发育和环境适应中扮演着至关重要的角色。近年来, 随着基因编辑技术的不断进步, DA1肽酶的作用机制和功能逐渐被阐释。研究表明, DA1基因的表达受到转录水平的调控, 而其蛋白活性则受到翻译后修饰的调控。尽管对DA1肽酶生物学功能的研究有很多, 但是缺少对DA1肽酶不同功能系统而全面的总结。因此, 本综述主要介绍了DA1肽酶的分子结构, 重点阐述了其在调控器官大小、参与盐胁迫、干旱适应以及免疫反应激活等胁迫响应中的生物学功能。此外, 我们还对DA1肽酶在维管形成层活性调节和生长素信号转导中的作用进行了总结。本文旨在加深人们对DA1肽酶复杂功能和调控网络的理解。

DA1 peptidase is a key plant protease that is widely present in various plants and plays crucial roles in plant growth, development, and environmental adaptation. In recent years, with the improvement of gene editing technology, the mechanism of function of DA1 peptidase have gradually been elucidated. Considerable effort has been devoted to showing that DA1 peptidase is regulated at the transcriptional and post-translational modification levels. Although there are plenty of studies on specific biological functions of DA1 peptidase, there still lacks systematic and comprehensive summaries of the progress of DA1. This review briefly introduces the molecular structure of DA1 peptidase, summarizes the regulatory mechanisms of DA1 peptidase, and focuses on its biological functions in regulating organ size, participating in salt stress, drought adaptation, and activating immune responses in stress responses. In addition, we have summarized the role of DA1 peptidase in the regulation of vascular cambium activity and auxin signal transduction. This review aims to deepen the understanding of the complex functions and regulatory networks of DA1 peptidase.
