Toxicological evaluation of transgenic silkworms.

Safety of transgenic silkworms must be evaluated before their commercial application. We assessed subacute toxicity using a 28-day feeding study in rats. Eighty rats were evenly allocated into four groups, with each group containing 10 male and 10 female rats.

Heat shock protein 19.9 (Hsp19.9) from Bombyx mori is involved in host protection against viral infection.

Adverse environmental conditions cause serious economic losses in sericulture; Bombyx mori nucleopolyhedrovirus (BmNPV) is the primary biotic stress and high temperature is the major abiotic stress in this industry. B. mori heat shock protein 19.
