Distinguishable microbial functional profiles between rumen metagenome and metatranscriptome datasets. a PCA for eggNOG functional categories, which was calculated based on auto-scaled abundances (cpm) of functional categories. b Correlation between metagenome and T-metatranscriptome. c Correlation between metagenome and M-metatranscriptome. Each scatterplot in b and c illustrates log10-transformed mean abundances (cpm) of each functional category at DNA and RNA levels
