Comparison of the prokaryotic metatranscriptomic profiles for luminal fluid (LF) and whole termite guts (WG) RNA preparations. a Prokaryotic gene transcripts annotated to Clusters of Orthologous Group (COG) categories. b Distribution of prokaryotic transcripts to CAZy families (only contigs with e-value <1e−18 and coverage >0.35 are shown). Different families within the same class are distinguished by the colour gradient. Numbers on the top of each bar pair represent the calculated Spearman correlation coefficient between pairs of samples. All levels of significance are <0.001
