Heatmaps of log2 normalized abundances of different features. (A) Lignocellulolytic enzymes annotated to CAZy families, (B) lignocellulolytic enzymes annotated to KEGG Orthology entries, (C) bacterial phyla and (D) nitrogen metabolism-related enzymes annotated to KEGG Orthology (KO) entries. Samples are clustered according to phylogenetic relationship reported in Tsang et al. [60]. Sample names are colored according to the dietary groups and symbols correspond to the family. Features are arranged according to enzyme categories in A, B and D; and by alphabetical order in C. Differentially abundant features detected in pairwise comparisons with the consensus in at least two of the differential abundance testing tools (ALDEx2, ANCOM-BC and DESeq2) among dietary groups are denoted by asterisks in the table below the heatmap
