Soil Type Influences Rhizosphere Bacterial Community Assemblies of Pecan Plantations, a Case Study of Eastern China

The rhizosphere microbiome is closely related to forest health and productivity. However, whether soil type affects pecan (Carya illinoinensis) microbiomes unclear. We aimed explore the diversity structural characteristics of bacteria associated with plantations grown in three types (Luvisols, Cambisols, Solonchaks) Eastern China analyze their potential functions through high-throughput sequencing. results showed that community structure were significantly affected by pH, available phosphorus content, electrical conductivity, moisture, ammonium nitrogen contents main factors. At phylum level, bacterial composition was consistent, mainly included Actinobacteria, Proteobacteria, Acidobacteria, Chloroflexi. family formed different enriched biomarkers due influence type, functional such as plant growth promotion nutrient cycling. In addition, there existed low abundance core species Haliangiaceae, Bryobacteraceae, Steroidobacteraceae. They played important roles environments linkages. Overall, this study provides a basis for plantations, plays an role sustainable management soil.
