Protein post-translational modifications(PTMs)play a crucial role in plant growth and development.They significantly impact plant growth,development,and the ability to adapt to environmental stresses by fine-tuning the structure,stability,and activity of proteins.While the lignin biosynthetic pathway and its upstream transcriptional regulation have been extensively inves-tigated,research on PTMs in this context remains relatively limited.This review summarized the latest advancements in under-standing the regulation of lignin biosynthesis by PTMs,particularly focusing on four significant types:phosphorylation,ubiqui-tination,glycosylation,and S-nitrosylation.It highlighted the regulatory mechanisms of these PTMs on key enzymes and tran-scription factors involved in lignin biosynthesis,aiming to enhance our comprehension of the regulatory networks governing lignin biosynthesis and provide valuable insights and references for the precise spatiotemporal modulation of this crucial process in plants.
