Research Progress on Post-translational Modifications of Starch Biosynthesis-related Proteins in Rice Endosperm
摘要
Abstract
Protein post-translational modifications(PTMs)serve as a crucial regulatory mechanism of protein function and play a significant role in rice seed development and endosperm starch biosynthesis.With advancements in pro-teomics technologies,numerous starch synthesis-related proteins in rice endosperm have been identified to undergo various PTMs.This review summarizes the proteomic analyses,modification sites,pathways,and biological functions of six major types of PTMs in starch synthesis-related proteins in rice endosperm:phosphorylation,lysine acetylation,suc-cinylation,2-hydroxyisobutyrylation,malonylation,and ubiquitination.Among these,protein phosphorylation has been the most extensively studied and is recognized as a key regulator of plant growth,development,and starch metabolism.Ad-ditionally,we discuss the potential roles of PTMs in grain filling,rice starch quality,and appearance.This review provides insights into the regulatory mechanisms of PTMs in starch synthesis-related proteins in rice endosperm,offering a valu-able reference for breeding high-yield and high-quality rice varieties.关键词
