Fig. 1From: Phytoplankton-derived polysaccharides and microbial peptidoglycans are key nutrients for deep-sea microbes in the Mariana TrenchTaxonomic profiling of the microbial community composition throughout the water column. Microbial community profiling at the class level based on the metagenomic (A) and metatranscriptomic (B) data. Dominant microbial groups at genus level based on the metagenomic (C) and metatranscriptomic (D) data. E Correlation between DNA-based and RNA-based relative abundance at the genus level. Sample names are defined by sampling depth. Dot size in the panel C and D is proportional to the relative abundance of microbial groups. The genera shadowed in colorful boxes are from the same class groupBack to article page
