Abstract The tree microbiome is a critical determinant of and ecosystem functioning, but human disturbances can disrupt natural microbe-tree relationships. Here, we show that urban trees exhibit microbial dysbiosis along model urbanization gradient, with declines in mutualistic root leaf symbionts, increases decomposers pathogens, including those relevant to plant, animal, health. These shifts correlate stressors such as heat, drought, atmospheric deposition. Urban microbiomes also altered biogeochemical cycling capabilities, high potential for nitrogen loss through greenhouse gas (N2O) production reduced capacity methane consumption relative rural trees. Additionally, reduces overall diversity, particularly among non-pathogenic microbes, potentially diminishing the ecological health benefits diverse environmental cities. findings underscore need consider forestry management practices maximize city greening forest conservation efforts.
