Comparative analysis between the species-level representative genomes (SRGs) from the MEER dataset and the species-level genomes in the Ocean Microbiomics Database (OMD), the typical deep-sea and hadal sediment. The OMD included isolated reference genome (ISO) of Global Ocean Reference Genomes (GORG), single-cell amplified genome (SAG) of MAR Database (MARD), as well as seawater metagenomes of abyssopelagic layer (ABY, 4,500-6,000 m), bathypelagic layer (BAT, 1,000-4,500 m), mesopelagic layer (MES, 200-1,000 m), and epipelagic layer (EPI, 0-200 m). Doughnut charts illustrate the sample habitat distribution in each habitat. Bar plots depict the distribution of MEER SRGs detected in reference habitats.
