Fig. 4From: The majority of microorganisms in gas hydrate-bearing subseafloor sediments ferment macromoleculesAbundance and expression of metabolic marker genes in the deep subsurface sediments from the gas hydrate zone. a The abundance of each gene in metagenomes. b The abundance of each transcript in the metatranscriptomes. Gene and transcript abundances are represented in units of genes per million (GPM) and transcripts per million (TPM), respectivelyBack to article page
