叶际微生物群落的研究进展
Research advances on the phyllosphere microbial community
摘要
Abstract
The phyllosphere,as a unique microbial habitat,harbors highly diverse and abundant microbial communities.This review systematically examines the development of research on phyllosphere microbiota,with a particular focus on the compositional characteristics and assembly mechanisms of phyllosphere microbial communities.Based on the latest theoretical framework of evolutionary community ecology,the paper explores in-depth four key ecological processes that influence the assembly of phyllosphere microbial communities:selection,dispersal,diversification and drift.In terms of dispersal,phyllosphere microbes are primarily transmitted through vertical and horizontal pathways.The vertical pathway involves microbial transfer from soil to plant seeds and subsequently to the phyllosphere,while horizontal dispersal mainly relies on air as a medium,facilitating microbial colonization and community formation on plant leaf surfaces.Regarding diversity,the composition of phyllosphere microbial communities is influenced by multiple factors,including abiotic stressors and horizontal gene transfer,which collectively drive the generation and maintenance of microbial diversity.Additionally,drift,as a stochastic ecological process,primarily regulates the overall microbial community structure by affecting the abundance of rare species.A thorough understanding of the ecological functions,mechanisms of action,and host-microbe interactions of phyllosphere microbes is of significant theoretical importance for elucidating plant health maintenance mechanisms and ecosystem functions.Future research directions should focus on deciphering the ecological functions of phyllosphere microbes and strengthening the development of model systems to comprehensively reveal the crucial roles of phyllosphere microbiota in plant ecosystems.关键词
