| contents | Trophic strategy drives the diversity and community composition of arsenic methylating prokaryotes in intestines of coral reef fish. Chen, Lizhao Deng, Nanling Lin, Haoye Zhong, Jiarui Zhang, Li Animals Coral Reefs Arsenic Fishes Gastrointestinal Microbiome Water Pollutants, Chemical Bacteria Archaea Biodiversity Food Chain Methylation Intestines Arsenic methylation by gut microbiota is the primary detoxification pathway for arsenic in marine fish. Furthermore, the composition and function of the gut microbiome are closely linked to host diet, which differs considerably among the diverse trophic guilds of coral reef fish. However, it remains unexplored whether and how the trophic strategy of the host fish fundamentally shapes the diversity and community composition of arsenic methylating prokaryotes within this complex intestinal environment. In this study, taxonomic databases based on arsenite methylating gene (arsM) for arsenic methylating archaea (AMA) and bacteria (AMB) with respective 143 and 105 non-redundant sequences were established and used for analyzing the diversity and community composition of AMA and AMB in the intestines of coral reef fish. The diversity of AMA and AMB was the highest in the intestines of omnivorous fish, while the highest abundances of AMA and AMB were detected in carnivorous fish. Haloarculaceae and Streptomycetaceae were the most abundant families of AMA and AMB, respectively. A significant difference in community composition was found only in the intestinal AMA of coral reef fish across different trophic strategies. This study demonstrates that trophic strategy is a key driver shaping the gut arsenic methylating prokaryotes in coral reef fish, offering novel insights into the mechanistic links between host ecology, gut microbiome assembly, and arsenic detoxification capacity in coral reef ecosystem. |
