Diversity and Structure of Vegetation Rhizosphere Bacterial Community in Various Habitats of Liaohekou Coastal Wetlands

Coastal wetlands are a type of unique ecosystem, in which rhizosphere microorganisms vegetation play significant role the overall ecology. Rhizosphere soil samples from Liaohekou Wetlands, Northeast China (40°54?44? N, 121°47?51? E), were collected seven habitats (Suaeda and Phragmites community different coverage, aquaculture ponds farmland biotopes) to evaluate diversity structure bacterial using high throughput sequencing. Soil physicochemical characteristics communities found be affected by coverage ANOVA tests. As Ni main heavy metal variables affecting as demonstrated RDA tests, while NO3?-N important nutrient factors. Proteobacteria was predominant phylum all soils. Gillisia Woeseia two most dominant genera peculiarly Suaeda community. Meanwhile SparCC showed that wetland communities. The Chemoheterotrophic function with FAPROTAX results, cycle Sulfur Nitrogen significantly coverage. In conclusion, this study revealed structural composition under types This research could help deepen our understanding microbial ecology on provide information various habitats.
