摘要
The phyllosphere is a fluctuant micro-environment habitat that harbors diverse microbial communities that have the potential to influence plant growth through their effect on host fitness. However, we know little about the driving factors of phyllosphere microbial functional traits, e.g., genes related to nutrient cycling and microbial community structure under anthropic disturbance. Here, we characterized phyllosphere microbial communities and the abundance of genes related to nutrient cycling from diverse plant species between urban and natural habitats. We measured leaf functional traits to investigate the potential drivers of the phyllosphere microbial profile. Results indicated that phyllosphere microbial communities differed significantly between urban and natural habitats, and that this variation was dependent upon plant species. Host plant species had a greater influence on the abundance of genes involved in nutrient cycling in the phyllosphere than habitat. In addition, phyllosphere microbial diversity and functional gene abundance were significantly correlated. Furthermore, host leaf functional traits (e.g., specific leaf area and nutrient content) were potential driving factors of both phyllosphere microbial community structure and the abundance of genes involved in nutrient cycling. These findings contribute to a better understanding of the phyllosphere microbiome and its biotic and abiotic controlling factors, which improves our understanding of plant-microbe interactions and their ecosystem functions under anthropic disturbance.
