Phylogenetic analysis of all chitin-binding domains (CBDs) of chitinases from eleven different insect species: Acromyrmex echinatior (Ae), Anopheles gambiae (Ag), Brugia malayi (Bma), Caenorhabditis elegans (Ce), Camponotus floridanus (Cf), Danaus plexippus (Dpl), Daphnia pulex (Dp), Drosophila melanogaster (Dm), Harpegnathos saltator (Hs), Manduca sexta (Ms) and Tribolium castaneum (Tc). The accession numbers of all the proteins used are listed in Supplementary Table 1. CHTs containing a CBD are grouped into 6 different groups out of the 10 described for CHTs (Tetreau et al., 2015): group I (light purple), group II (green; °), group III (light blue; ~), group IV (brown; *), group VI (dark blue) or group X (orange). As CHT7 chitinases from C. elegans and B. malayi (indicated by a ~) have a divergent domain organization from other group III chitinases (Tetreau et al., 2015), they are highlighted by a hatched light blue area. CHTs from M. sexta are indicated in bold. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
