Polymorophic Analysis of Silkworm Vitellogenins
We cloned and sequenced cDNA of Bombyx mandarina vitellogenin (BmaVg) inhabiting Japan. The complete sequence of BmaVg cDNA without a poly A tail is 5733bp long and encodes 1780 amino acid residues among which are typical highly conserved sequences and common features found in most insects. Multiple alignment of vitellogenin sequences of Japanese Bombyx mandarina, the Chinese one, and Bombyx mori (Bmo) showed that BmaVg (JPN) is more similar to BmaVg (CHN) than to BmoVg. The phylogenetic tree of Vgs demonstrates that BmaVgs of individuals collected from eighteen prefectures in Japan primarily cluster in a group with BmaVg (CHN) and without BmoVg, suggesting that the sequence variation between the two BmaVgs arose after divergence of B. mori from B. mandarina. The Antheraea yamamai vitellogenin gene (AyVg gene) is composed of seven exons separated by six introns, the organization of which is similar to that of Bombyx mori.
