Fig. 2

Relative abundance of CAZymes found in gut metagenomes of termites. The heatmap shows the 50 most abundant CAZymes. The color scale represents the logarithm of transcripts per million (TPM). The tree represents a simplified time-calibrated phylogenetic tree reconstructed using host termite mitochondrial genomes. Genes showing significant phylogenetic autocorrelation with the host phylogeny at a 5% false discovery rate (FDR) are indicated with asterisks (*p < 0.05; **p < 0.01)
