16S rRNA gene amplicon sequencing of rhizosphere soil from Suaeda salsa under biochar and AMF treatments
Soil salinization is a major environmental stressor limiting plant growth and ecosystem productivity. This study investigates the synergistic effects of biochar (BC) and arbuscular mycorrhizal fungi (AMF) on the salt tolerance of the halophyte Suaeda salsa. We performed 16S rRNA gene amplicon sequencing (V3-V4 region) of rhizosphere soil samples from four key treatment groups: unamended control (A0B0), BC alone (A0B3), AMF alone (A3B0), and combined BC+AMF (A3B3). The aim was to characterize shifts in bacterial community composition and identify taxa enriched under different amendment strategies. The raw sequence data support the analysis of microbial community structure presented in the associated manuscript, contributing to a mechanistic understanding of how BC and AMF jointly improve plant health under saline conditions.
