DA1 peptidase is a key plant protease that and plays crucial roles in plant growth, development, and environmental adaptation. In recent years, with the improvement of gene editing technology, the function mechanism of DA1 peptidase have gradually been elucidated. All studies show that DA1 peptidase is regulated at the transcriptional and post-translational levels. Although there are plenty of studies on specific biological functions of DA1 peptidase, there still lacks systematic and comprehensive summaries of the research progress on DA1. This review briefly describes the molecular structure of DA1 peptidase, summarizes the regulatory mechanisms of DA1 peptidase, and focuses on its biological functions in regulating organ size, responding to salt and drought stresses, and activating immune responses to biological stresses. 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 provide a comprehensive understanding of the complex functions and regulatory networks of DA1 peptidase.
