From: Diverse hydrogen production and consumption pathways influence methane production in ruminants
Hydrogenase content in the metagenomes and metatranscriptomes of the microbial communities within rumen contents of high and low methane yield sheep. Hydrogenase content is shown based on hydrogenase subgroup a, b and predicted taxonomic affiliation c, d for metagenome data sets a, c and metatranscriptome data sets b, d. Hydrogenase-encoding sequences were retrieved from 20 paired shotgun metagenomes and metatranscriptomes randomly subsampled at five million reads. Reads were classified into hydrogenase subgroups and taxonomically assigned at the order level based on their closest match to the hydrogenases within the genomes screened (Fig. 1). L01 to L10 are data sets for sheep that were low methane yield at time of sampling, H01 to H10 are data sets from sheep that were high methane yield at time of sampling (see Table S3 for full details)
