The category and abundance of the genes involved in the polymer degradation and utilization at each depth. A, B, and C The category, DNA-based and RNA-based abundance (represented by TPM value) of the genes that contained/transcribed CAZymes (A), peptidases (B), and transporters (C) genes. A CAZyme families: GH: glycoside hydrolase; PL: polysaccharide lyase; CE: carbohydrate esterase; AA: auxiliary activity. B Peptidase families: cysteine (C), metallo (M), and serine (S) peptidases. C Transporters: sugars (monosaccharides, disaccharides, and oligosaccharides), amino acids, branch-chain amino acids (BCAAs), peptides, and TonB transporters
