Plant-microbe interactions derive the rhizosphere microbial assembly and nitrogen cycling in a subtropical forest

1. Interactions between plants and soil microorganisms in the rhizosphere are vital for maintaining the nutrient cycle and stability of terrestrial ecosystems. Nitrogen, closely related to carbon (C) cycling and ecosystem productivity, undergoes transformation by soil microorganisms into forms that can be assimilated by plants. However, the mechanism by which plants impact nitrogen (N) cycling in acid subtropical forest soil by governing the rhizosphere microbial community remains unclear. 2. This study examined the impact of host phylogeny, root traits, and soil properties on microbial communities and N cycles in the rhizospheres of Fagaceae and Lauraceae, the two dominant families in the subtropical forest of Heishiding Natural Reserve in southern China. 3. Our findings revealed that host phylogeny dominates the variation in the richness and composition of the rhizosphere microbial community. Furthermore, antibacterial exudates from Lauraceae might reduce the stability of microbial ne..., , , # Plant-microbe interactions derive the rhizosphere microbial assembly and nitrogen cycling in a subtropical forest

## Description of the data and file structure

Rhizosphere soil samples of Lauraceae and Fagaceae were collected from typical subtropical forests in Heishingting Nature Reserve, South China. DNA of soil samples was extracted and 16S rRNA gene amplicon sequencing was performed.
