Fig. 1From: Revealing the full biosphere structure and versatile metabolic functions in the deepest ocean sediment of the Challenger DeepComposition and phylogenetic diversity of the microbial community in the Challenger Deep sediment habitat. A The relative sequence abundance of dominant microbial groups (top 30). B Phylogenetic analysis of the 178 MAGs based on 43 conserved single-copy, protein-coding marker genes using the maximum likelihood algorithm. Bootstrap values based on 1000 replications are shown for each branch. The scale bar represents 0.1 amino acid substitution per positionBack to article page
