植物磷酸盐转运蛋白在胁迫响应中的研究进展
Research Progress of Plant Phosphate Transporters in the Response to Stress
摘要
Abstract
Phosphorus(P)is an essential element for plant growth,development and many physiological functions.Phosphate transporters are responsible for the uptake and transport of phosphorus from the soil to plant organelles and play a significant role in plant growth and development as well as in responses to abiotic and biotic stresses.This article reviews the classification,structural characteristics,subcellular localization of plant phosphate transporters and their important roles in plant responses to abiotic and biotic stresses.Plant phosphate transporters can be divided into three major classes,with the first class further divided into five subfamilies.These proteins perform functions in different parts of the plant.Plant phosphate transporters not only participate in the absorption and transport of phosphate but also play a crucial role in stress responses.Under abiotic stress,plant phosphate transporters are induced to express,which can enhance the plant´s tolerance to abiotic stress by increasing its antioxidant capacity.In addition,plant phosphate transporters interact with other proteins to regulate plant responses to abiotic stress.Under biotic stress,plant phosphate transporters regulate the transcriptional levels of defense-related genes in plants,thereby positively or negatively regulating plant resistance to pathogens.Existing studies have demonstrated the important role of plant phosphate transporters in stress responses,but their specific molecular mechanisms and regulatory networks still need further exploration.Future research directions will focus on screening and identifying upstream regulatory factors and downstream interacting target genes of plant phosphate transporters,and deeply elucidating the molecular mechanisms by which plant phosphate transporters regulate biotic and abiotic stress responses,with the aim of providing references for the efficient utilization of phosphorus in crops and high-yield and high-resistance molecular breeding.关键词
