Cloning and alternative splicing analysis of Bombyx mori transformer-2 gene using silkworm EST database.

We have identified Bombyx mori transformer-2 gene (Bmtra-2) cDNA by blasting the EST database of B. mori. It was expressed in the whole life of the male and female silkworm and was observed as a band of 1.

Influence of form and quantity of chromium on the development and survival of two silkworm (Bombyx mori L.) races.

Growth inhibitory activity has proven important in Qiufeng x Baiyu and Qingsong x Haoyue silkworm larvae. The consumption of mulberry leaves was reduced in both silkworm races while Qiufeng x Baiyu larvae showed the higher reduction in leaf consumption. From the results obtained, it was revealed that even at low concentrations of 400 mg/L of either Cr(III) or Cr(VI) ions, growth of Qiufeng x Baiyu and Qingsong x Haoyue was significantly depressed.
