Phylogenetic tree of chordate chitinases/chitolectins. The figure shows the minimum evolution tree from a phylogenetic analysis conducted as described in the legend for Figure 1. Besides mammals, the species are X. tropicalis (Xtr), D. rerio (Dre), G. gallus (Gga), M. domestica (Mdo) and C. intestinalis (Cin). Gene or protein symbols are used for mammals; Gene ID numbers for X. tropicalis, D. rerio and G. gallus; Genscan Gene Prediction symbols for M. domestica; and the JGI Model protein ID number for C. intestinalis. Groups A-E and their correspondence to subgroups I-IV in Fig. 1 are described in the text. Scale, rooting and bootstrapping are as described for Figure 1. Bootstrap values ≥ 50% are shown.
