Additional file 13: of Metatranscriptomic analysis of diverse microbial communities reveals core metabolic pathways and microbiome-specific functionality

Taxonomic contributions to select hydrogenase modules as defined through protein-interaction networks for the four well sampled datasets. Each network indicates the taxonomic representation of components of hydrogenases as defined through protein-interaction networks for four metatranscriptome datasets: mouse, kimchi, cow and deep sea. Pie charts indicate genes, with coloured sectors indicating the relative contribution to gene expression for each taxon, size of pie chart indicates relative expression (see key). (PDF 190 kb)
