Specific soil factors drive the differed stochastic assembly of rhizosphere and root endosphere fungal communities in pear trees across different habitats

The assembly of root-associated fungal communities in <i>P. betulifolia</i> is not only driven by soil physicochemical properties but also influenced by root compartment niche and topography. Moreover, the impact intensity of the root compartment niche is greater than topography. Specifically, the assembly of the rhizosphere fungal community was primarily influenced by alkaline nitrogen (AN) and alkaline phosphatase (ALP), while the root endosphere fungal community was more strongly affected by pH and sucrase (SUC). These findings could provide valuable insights for the design of beneficial root-associated microbiomes to enhance fruit tree performance.
