摘要: The bacterial communities played important roles in the high productivity mangrove ecosystem. In this study, we investigated vertical distributions of rhizosphere bacteria from three species (Bruguiera gymnorrhiza, Kandelia candel and Aegiceras corniculatum) Beilun Estuary, China using throughput DNA pyrosequencing 16S rRNA gene. Phylogenetic analysis showed that sediments were dominated by Proteobacteria (mostly Deltaproteobacteria Gammaproteobacteria), followed Chloroflexi, Bacteroidetes, Planctomycetes Acidobacteria. However, ANOVA on Shannon Chao1 indices indicated among varied more strongly than sampling depths. addition, PCA result demonstrated could be separated into groups according to species. Moreover, orders Rhodospirillales, GCA004 envOPS12 significantly different results study provided valuable information about distribution feature Chinese plants shed insights biogeochemical transformations driven sediments.
