Geographic Variation Characteristics of Endophytic Bacterial Communities in Roots of Hippophae rhamnoides subsp. Sinensis Rousi in the Arid Region of Northwest China
In this study, root samples of H. rhamnoides were collected from 12 provenances across the arid region of Northwest China. High-throughput amplicon sequencing was employed to examine bacterial composition, alpha and beta diversity, molecular co-occurrence networks, and PICRUSt-based functional prediction. Mantel tests and redundancy analysis (RDA) were further applied to identify the key drivers shaping bacterial community structure.
