Molecular size of the diapause hormone of the silkworm Bombyx mori.

The silk proteins, sericin and fibroin in silkworm, Bombyx mori Linn., - a review

The domesticated silkworm, Bombyx mori Linn., a lepidopteran molecular model and an important economic insect that are emerging as an ideal molecular genetic resource for solving a broad range of biological problems. The silkworm, B. mori produces massive amount of silk proteins during the final stage of larval development. These proteins are stored in the middle silk gland and they are dischar...

Studies on the Mode of Action of the Diapause Hormone in the Silkworm, Bombyx Mori L. Vi. the Target Organ of the Diapause Hormone

Embryonic thermosensitive TRPA1 determines transgenerational diapause phenotype of the silkworm, Bombyx mori.

In the bivoltine strain of the silkworm, Bombyx mori, embryonic diapause is induced transgenerationally as a maternal effect. Progeny diapause is determined by the environmental temperature during embryonic development of the mother; however, its molecular mechanisms are largely unknown. Here, we show that the Bombyx TRPA1 ortholog (BmTrpA1) acts as a thermosensitive transient receptor potentia...

Linkage Map Construction for Silkworm (Bombyx mori L.) Based on Amplified Fragment Length Polymorphism Markers

The domesticated silkworm, Bombyx mori, is of high commercial importance as a silk producer and is also widely used for implementation of basic and applied research. It is important to understand its genome organization using molecular markers for genetic studies and for breeding purposes. In this study, a genetic linkage map using 204 amplified fragment length polymorphism (AFLP) markers was d...

Effect of Salicylic Acid on Commercial Traits of the Bivoltine Crossbreed Races of the Silkworm, Bombyx mori L.

Topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine CSR2, CSR4 and CSR2XCSR4 crossbreed races of the silkworm, Bombyx mori L. The results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoo...
