Survey of methane cycling genes and transcripts. Left—relative global activity survey for 37 dominant lineages, arranged based on phylogenomic relatedness and color-coded at the phylum-level of taxonomy, in the A. aerophoba-associated microbiome. Relative activity is represented by circle size and depicts mean values per lineage from eight independent metatranscriptomes: four sponge specimens sampled twice, at noon 24 h apart (see Fig. S2 for individual results). Right—methane-relevant genes and gene transcripts detected in MAGs and in the metatranscriptomes are depicted by black and red “X” symbols, respectively
