| Abstract | Phyllosphere and numerous phyllospheric microbiomes present a huge potential for air pollution mitigation. Despite research investigating the microbial compositions in the phyllosphere, the successions and interactions of the phyllospheric microbiome under ammonia gas (NH3) stress remain poorly understood. Herein, we performed 16S rDNA, the internal transcribed spacer (ITS) profiling and a quantitative microbial element cycling (QMEC) method to reveal successions, co-occurrence, and N-cycling functions changes of phyllospheric bacteria and fungi during NH3 exposure. The NH3 input mainly elevated ammonium (NH4+-N) and total nitrogen (TN) levels on the leaf surface. The exposure in the phyllosphere decreased fungal concentration with a homogeneity increase while enhanced bacterial concentration with a noticeable richness drop. Both short-term (2-week) and long-term (6-week) exposure induced significant changes in microbial compositions. Bacterial genera (Nocardioides, Pseudonocardia) and fungal genera (Alternaria, Acremonium) dominated throughout the exposure. Intensive microbial interactions compared to that in the natural phyllosphere were observed via network analysis. Our results showed that N-cycling functional genes were largely stimulated by the exposure and might, in turn contribute to NH3 pollution buffer and alleviation via microbial metabolism. This study extended the knowledge on microbial responses to NH3 exposure in the phyllosphere and enlightened phylloremediation on NH3 through the microbial role. |
