合成微生物群落增强植物抗旱性的研究进展
Research Progress in the Enhancement of Plant Resistance to Drought by Synthetic Microbial Communities
摘要
Abstract
Global climate warming has led to more extensive,severe,and frequent droughts,which in turn have reduced plant productivity and posed a serious threat to agricultural production.Plants respond to drought stress through their own physiological regulation.As an important intermediate signal transmitter,rhizosphere microorganisms secrete signal molecules that can regulate plant phenotypes and enhance the ability of plants to resist drought.However,the natural rhizosphere microbial community in natural environment has high species diversity and functional complexity,which brings great challenges to the in-depth study of rhizosphere signaling mechanisms.In contrast to its clear functional structure,synthetic microbial communities(SynComs)show significant potential and unique advantages in accurately regulating rhizosphere signaling and systematically enhancing plant drought resistance.This paper reviews the design of SynComs to strengthen the positive effect signal flow in the rhizosphere from the perspective of strengthening plant-microbe and microbe-microbe interactions,and deeply analyzes the transmission mechanism from the perspectives of quorum sensing and cross-feeding,so as to provide a theoretical basis and practical strategies for establishing a predictable and efficient new path of agricultural microecological regulation.关键词
