Intertidal mangrove wetlands are of great economic and ecological importance. The regular influence of tides has led to the microbial communities in these wetlands differing significantly from those in other habitats. In this study, we investigated the microbiomes of the two largest mangrove wetlands in Hainan Island, China, which have different levels of anthropogenic protection. Soil samples were collected from the root zone of 13 mangrove species. The microbial composition, including key functional groups, was assessed using Illumina sequencing. Bioinformatics analysis showed that there was a significant difference in the microbiomes between the protected Bamen Bay and the unprotected Dongzhai Bay. The overall microbiome was assigned into 78 phyla and Proteobacteria was the most abundant phylum at both sites. In the protected wetland, there were fewer marine-related microbial communities, such as sulfate-reducing bacteria, and more terrestrial-related communities, such as Verrucomicrobia methanotrophs. We also observed distinct microbial compositions among the different mangrove species at the protected site. Our data suggest that the different microbiomes of the two mangrove wetlands are the result of a complex interaction of the different environmental variables at the two sites.
潮间带红树林湿地具有重要的经济和生态意义。潮汐的定期影响导致这些湿地中的微生物群落与其他栖息地的微生物群落存在显著差异。在本研究中，我们调查了中国海南岛两个最大的红树林湿地的微生物群落，这两个湿地受到的人为保护程度不同。从13种红树植物的根区采集土壤样本。使用Illumina测序评估微生物组成，包括关键功能组。生物信息学分析表明，受保护的八门湾和未受保护的东寨港之间的微生物群落存在显著差异。整体微生物群落被分为78个门，变形菌门是两个地点最丰富的门。在受保护的湿地中，与海洋相关的微生物群落较少，如硫酸盐还原菌，而与陆地相关的群落较多，如疣微菌甲烷营养菌。我们还在受保护地点的不同红树植物物种中观察到了不同的微生物组成。我们的数据表明，两个红树林湿地不同的微生物群落是两个地点不同环境变量复杂相互作用的结果。
