Fig. 5: Abundance, transcription and taxonomic information of the CAZyme gene families with the highest proportional transcription across samples.

a The abundance and transcription of carbohydrate-active enzyme (CAZyme) genes was normalised by the number of microbial genomes per sample and then converted to relative proportions. The selected CAZyme gene families visualised are those that reached the highest proportions of transcription across samples. b The genera that contributed the most to transcription of each gene family in each metatranscriptome. Taxonomic classification of CAZyme genes was derived from the classification of the read from which it was derived.
