Figure 2. Ommochrome-binding protein gene (obp) phylogeny generated from a 516 nt consensus alignment from nucleotide positions 246 and 762 of the O. furnacalis diapause associated polypeptide (DAP; GenBank accession no. AF169311). Other OBP gene sequences include O. nubilalis obp1 alleles Onobp2-A1 and -A2, and obp2 alleles Onobp2-A1, -A2, and -A3 (See Fig. 1), M. sexta (M Sexta OBP; GenBank accession no. L00975), and Bombyx mori (Bm) expressed sequence tag sequences from fat body (fbVm022) and ovarian tissue (ovS318H0, and ovS10G0).
