Regulatory Mechanisms of Small Peptides in Plant Meristem Development and Its Research Advances in Crop Improvement
摘要
Abstract
Throughout the growth and development of higher plants,the shoot apical meristem(SAM)and root apical meristem(RAM)continually differentiate to generate roots,stems,leaves and flowers,then forming above-ground and below-ground organs,respectively.As one of important intercellular signal transduction molecule,small peptides are involved in regulation of many physiological processes in plant development and resistance to biotic and abiotic stress.Particularly,they play crucial role in regulating the activity of SAM and RAM,which ultimately affect the origin and development of plant organs.In recent years,emerging evidences reveal the importance roles of small peptides in maintaining meristems homeostasis and regulating crop agronomic traits.This review highlights the biological functions and molecular mechanisms of small peptides and their receptors in maintaining the homeostasis of meristems in Arabidopsis and crop species.It also discusses the role of small peptides in regulating crop yield traits and their application in crop improvement.Additionally,the review proposes and prospects the potential interesting research direction of small peptides.关键词
