植物小分子信号肽参与非生物逆境胁迫应答的研究进展
Research Progress in Plant Small Signaling Peptides Involved in Abiotic Stress Response
摘要
Abstract
Plant small signaling peptides(SSPs)are a class of small peptides with a protein length of less than 120 amino acids.They play an important role as novel signaling molecules in plant responses to abiotic stresses.There are over thousand kinds of SSPs in plants.Their diverse structural features,modification processes,and the binding of different receptors exert their specific functions to participate in the interactions between plants and their environment.The identification of functional genes of plant SSPs and the analysis of their regulatory mechanisms in response to abiotic stresses are of great theoretical and practical importance for enhancing plant resistance and improving plant growth.Plant SSPs mainly include four major categories:extracellular non-secretory small peptides,intracellular non-secretory small peptides,extracellular post-translational modified secretory small peptides,and extracellular cysteine-rich secretory small peptides.We briefly describe four types of plant SSPs'structure and characteristics in this review.We also elucidate their regulatory mechanisms in which SSP ligands bind to LRR-RLK receptor kinases to complete the signal transduction process and activate the expressions of downstream resistance genes.We mainly elaborate on their biological functions and their function mechanisms in response to abiotic stresses such as drought,high temperature,salinity,and nutrient deficiency.Finally,we discuss the future research directions and unresolved issues of plant SSPs.We also look forward to the development of corresponding SSPs-based growth regulators,aiming to provide new ideas for improving plant responses to environmental stress and achieving sustainable agricultural development.关键词
