An analysis of genetic variation and divergence in Indian tropical polyvoltine silkworm (Bombyx mori L.) genotypes
The genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. The results revealed that the single shell weight showed higher genetic variation such as PCV% (17.20%), GCV% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. The D2 (Mahalonobis? distance) statistics reveal...
متن کاملVertical transmission of nucleopolyhedrovirus in the silkworm, Bombyx mori L.
Nucleopolyhedrovirus (NPV) was tested for vertical transmission in the silkworm, Bombyx mori. Fifth instar larvae were exposed to four different dosages of BmNPV (830, 1300, 1800, and 2000OBs/larva) and a dosage of about 2000OBs/larva was found suitable for obtaining infected adults. Histopathological studies revealed the infection in susceptible tissues and organs initially, and at later stage...
متن کاملCharacterization of Klebsiella granulomatis pathogenic to silkworm, Bombyx mori L.
Bacterial disease of silkworm causes significant reduction of silk production leading to huge economic loss. This study aims to isolate bacteria from diseased silkworm and to determine its pathogenicity and antibiotic resistance. A strain of Klebsiella granulomatis has been isolated from silkworm haemolymph which was later identified on the basis of biochemical tests and 16S rRNA gene sequencin...
متن کاملBlastoderm formation in the silkworm egg (Bombyx mori L).
Embryogenesis in the egg of the silkworm. Bombyx mori, up to 24 h after oviposition was studied by light microscopy with special reference to nuclear migration and blastoderm formation. In Bombyx eggs blastoderm cells seem to form in a mechanism different from that usually seen in many other insect species; that is, in Bombyx eggs no typical cleavage furrows were seen. Cleavage nuclei which had...
متن کاملThe genome sequence of silkworm, Bombyx mori.
We performed threefold shotgun sequencing of the silkworm (Bombyx mori) genome to obtain a draft sequence and establish a basic resource for comprehensive genome analysis. By using the newly developed RAMEN assembler, the sequence data derived from whole-genome shotgun (WGS) sequencing were assembled into 49,345 scaffolds that span a total length of 514 Mb including gaps and 387 Mb without gaps...
