The β-1,3-glucanase related proteins (βGRPs) of H. armigera. (A) Schematic representations of the domain structure of H. armigera βGRPs. Lengths of the amino acid sequences are indicated. (B) Phylogenetic relationships of the βGRPs. Sequences of the βGRP family members from 5 H. armigera (Ha), 3 T. castaneum (Tc), 3 D. melanogaster (Dm), 4 B. mori (Bm), 2 A. mellifera (Am) PGRPs, 4 A. aegypti (Aa), and 2 M. sexta (Ms) are aligned to build the tree. Scale bar, 0.1 substitutions per site. Bacillus circulans (Bc) β-1,3-glucanase is included as an out-group.
