Soil <i>nifH</i>-harboring community assemblage varies across pecan cultivars.

ABSTRACT:

Introduction

This study focused on three pecan (Carya illinoinensis) cultivars ('Pawnee', 'Mahan', and 'Jinhua'), systematically assessing variations in soil nitrogenase activity, characteristics traits of nifH-harboring microbial communities across these cultivars.

Methods

Using high-throughput sequencing technology, differences in the diversity, community composition, and network structure of nifH-harboring communities in the rhizosphere and bulk soils of pecan were examined across cultivars.

Results

Both cultivar type and soil compartment had significant effects on nitrogenase activity (p < 0.01). Among the three cultivars, 'Mahan' exhibited the highest soil nitrogenase activity in both its rhizosphere and bulk soils relative to the othe
