随着全球气候不断变化,重塑地球的生物多样性和生态系统结构已成为共识,植物与叶际微生物之间的复杂关系日益受到关注.本研究综述了最新的科研成果,探讨了气候变暖、氮沉降、降水格局变化以及二氧化碳浓度增加等关键全球变化因子如何影响植物叶际微生物群落的多样性、结构和功能特性.研究表明,这些全球环境变化因子通过影响植物的生理机能、叶片特性及其分泌物,间接地改变了叶际微生物群落的结构和功能;指出当前研究的不足之处在于对植物-微生物-环境三者间相互作用机制的探索深度尚需加强.本研究不仅为理解全球环境变化对生态系统造成的广泛影响提供了新视角,也为制定有效的生态保护政策和农业管理措施提供科技支撑.
As global changes reshape earth's biodiversity and ecosystem structure,the complex interactions between plants and phyllosphere microorganisms have garnered increasing attention.This review synthesized re-cent research and examined how key drivers of global change-such as climate warming,nitrogen deposition,al-tered precipitation patterns,and elevated atmospheric carbon dioxide-impact the diversity,structure,and func-tional traits of phyllosphere microbial communities.These global change factors indirectly modified microbial community composition and function by affecting plant physiology,leaf traits,and secretions.Furthermore,the study identified a gap in understanding the mechanisms underlying plant-microbe-environment interactions.By providing new insights into the ecological consequences of global change,this review also offered critical guid-ance for developing effective conservation policies and agricultural management strategies.
