Depth differentiation of microbial communities and nutrient cycling functional genes in semi-arid riparian soil.

ABSTRACT:

Introduction

Microbial communities and their associated carbon, nitrogen, and phosphorus metabolic processes play a role in maintaining ecological functions and nutrient cycling in riparian zones. However, systematic research on the coupling mechanisms of carbon, nitrogen, and phosphorus biogeochemical processes in soil profiles of semi-arid riparian soil is still limited.

Methods

This study focused on the riparian zone of the Tuwei River, a typical semi-arid river. Metagenomic sequencing was used to analyze the composition of microbial communities and their carbon, nitrogen, and phosphorus metabolic functions across different soil depths along the river.

Results

The dominant taxa across all depths and river sections were Proteobacteria (average relative abunda
