In the present study, fresh Silkmoths were used for DNA extraction. The wings, legs and antennae of moths were cut with sterile scissors, crushed under liquid nitrogen to fine powdered content which yielded high resolution DNA bands using modified phenol chloroform extraction method. The genomic DNA from twelve different silkmoth genotypes was further checked for its suitability in DNA fingerpr...

so production of silkworm from silkworm egg rapidly increasing. Success of sericulture as a cash crop depends on the vitality and disease freeness of the silkworm seed applied to farmer. Production of silkworm seed is not only free from diseases but having high heterosis. It is necessary to count silkworm egg accurately to avoid loss to silkworm egg production industry and farmers or grainges. ...

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...

The silkworm, Bombyx mori, is one of the major insect model organisms, and its draft and fine genome sequences became available in 2004 and 2008, respectively. Transposable elements (TEs) constitute ~40% of the silkworm genome. To better understand the roles of TEs in organization, structure and evolution of the silkworm genome, we used a combination of de novo, structure-based and homology-bas...

Sericulture is one of the great inventions of the ancient Chinese. Besides the mulberry silkworm (Bombyx mori), Chinese farmers developed rearing of the Chinese oak silkworm (Antheraea pernyi) about 400 years ago. In this paper, the historic records of the origins and dispersal of the domesticated Chinese oak silkworm in China are summarized. The first document with clearly recorded oak silkwor...

A tropical climate prevails in most of the sericultural areas in India, where temperature increases during the summer lead to adverse effects on temperate bivoltine silkworm rearing and cause crop losses. Screening for thermotolerance in the silkworm, Bombyxmori L. (Lepidoptera: Bombycidae) is an essential prerequisite for the development of thermotolerant breeds/hybrids. In the current study, ...

BACKGROUND Coat protein complex I (COPI) vesicles, coated by seven coatomer subunits, are mainly responsible for Golgi-to-ER transport. Silkworm posterior silkgland (PSG), a highly differentiated secretory tissue, secretes fibroin for silk production, but many physiological processes in the PSG cells await further investigation. METHODOLOGY/PRINCIPAL FINDINGS Here, to investigate the role of ...
