Abstract

Abstract: Microbial communities in wetland soils play vital roles in biogeochemical cycling of nutrients. In this study, the soil samples were collected from Suaeda, reed and Suaeda -reed hybrid zones in Shuangtaizi River Estuary, Northeast China, and the rhizosphere bacterial communities were compared using Illumina MiSeq sequencing. The microbial richness, diversity and structure of bacterial communities varied greatly in reed and Suaeda . Canonical correspondence analysis and Mantel test indicated that pH was the most significant factor ( P < 0.05) in bacterial community assembly. Proteobacteria was the most dominant phylum, accounting for 45.7–58.0% of the total sequences. Thioprofundum, Thiohalomonas and Exiguobacterium were the predominant genera in Suaeda, while Exiguobacterium, Gillisia, Desulfomonile, Citrobacter, Thioprofundum and Acinetobacter were the core species in reed. PICRUSt analysis revealed similar functional profiles of rhizosphere microbiota in reed and Suaeda . Nitrate reduction related genes were abundant for nitrogen metabolism, whereas assimilatory sulfate reduction was the major process for sulfur metabolism. Graphical abstract: Unlabelled Image Highlights: Rhizosphere microbiota of reed and Suaeda was sequenced and compared. The pH of water and soil could greatly affect bacterial community assembly. Proteobacteria dominated the rhizosphere microbial assemblages. PICRUSt analysis predicted the functional profiles of rhizosphere microbiota.
