Abstract

This study investigated the rhizosphere bacterial communities of Zanthoxylum nitidum(Roxb.) DC.
Using an integrated approach combining 16S rRNA sequencing, redundancy analysis (RDA), and grey relational analysis (GRA) to unravel the correlation among soil environmental factors, microbial diversity, functional potential, and key medicinal compounds.
This study revealed for the first time the effects of environmental factors such as soil pH, organic matter content (ORM), altitude(HT), soil sand(SP) and soil silt (SSG) on the diversity of soil bacterial community, annotated and analyzed the functions of differential flora, and established the correlation between 15 main differential flora (such as Rudaea, Bradyrhizobium, Gemmatimonas) and nitidine chloride, which is the main medicinal active component of Zanthoxylum nitidum(Roxb.) DC.
This study provides theoretical basis and important reference for soil adaptability optimization of Zanthoxylum nitidum (Roxb.) DC cultivation from bacterial community regulation, and highlights the supporting value of the study for the sustainable development of medicinal plant resources.
