CAZyme families, and their taxonomic origin, for enzymes derived from contigs longer than 5000 bps and present in 10% of gut metagenomes. The color scale represents the log-transformed transcripts per million (TPM). The tree represents a simplified time-calibrated phylogenetic tree reconstructed using host termite mitochondrial genomes. Asterisks indicate significant differences among the four termite groups at 5% false discovery rate (FDR, *p < 0.05; **p < 0.01; ***p < 0.001)
