Research progress on the impact of global environmental change on phyllosphere microorganisms
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.
