Phylogenetic analysis of the CYP genes identified in R. dominica. This analysis showed that all identified R. dominica CYPs could be classified into one of the known T. castaneum clans. Furthermore, the differentially expressed CYPs belong to Clan 3 (four unigenes) and Clan 4 (two unigenes). All R. dominica genes were classified into one of the four known CYP clans previously found in the beetle T. castaneum. Bootstrap values > 75% are represented as black dots, whereas nodes with bootstrap support between 50 and 75% are shown as grey dots. Nodes with bootstrap support < 50% are collapsed. The R. dominica-specific expansions in Clans 3 and 4 containing the up-regulated CYPs are highlighted in light orange and light green, respectively. CYPs whose log₂FC is > 2 are marked with a red asterisk, whereas those with a log₂FC between 1 and 2 are marked with a red triangle. The scale bar is in substitutions per site
