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...

ns1 gene of Bombyx mori bidensovirus (BmBDV) consisted of 951 nucleotides encoding a deduced 316-amino aicd protein. In this study, the gene was cloned and fused in frame with a N-terminal 6×His tag under control of the polyhedrin promoter, which was transposed into the mini-attTn7 locus of a modified baculovirus vector. Transfection of Sf-9 cells with the resulting recombinant DNA was performe...

Abstract The structural and thermal properties of chitin chitosan isolated from different sources ( Artemia sp.cysts (from the Aral Sea) Silkworm pupae (Bombyx mori) ) were studied by using FTIR, XRD, DSC. It is shown, that samples have a similar structure, however, depending on differ in ratio phase composition. Two types crystalline modification structure α -and β-modifications are observed f...

A simplified methodology was developed to study the geometric form of multiple Bombyx mori Nucleopolyhedrovirus by scanning electron microscopy. The virus belongs to Baculoviridae family and was isolated from the silkworm Bombyx mori (L.) (Lepidoptera: Bombycidae). The polyhedra of Nucleopolyhedrovirus were obtained from the filtrate, inoculum and hemolymph of the silkworm experimentally infect...

Purpose: To investigate the potential activity of Bombyx mori and its formulations against isoproterenol (ISO) induced cardiotoxicity. Methods: Wistar rats were orally pretreated with the ethanol extract of Bombyx mori cocoons in two doses (250 and 500 mg/kg) for 30 days; rats were similarly pretreated with its polyherbal formulations incorporating Khamira Abresham sada (KAS) and Khamira Abresh...

O sm undalin, a glucoside of osm undalactone, isolated from the royal fern, Osmunda japonica, stim ulated the deterren t cell (“R recep tor” cells, associated with deter­ rency) in the medial sensilla styloconica of Bombyx mori. From the dose-response curve, the lower limit of detection was 3 .6 x l0 ~ 53 .6 x l0 “4 m. This is the first re­ port tha t glucoside lactone elicits the impulses from...

Silk from the Bombyx mori silkworm is a protein-based fiber. Bombyx mori silk fibroin (SF) is one of the most important candidates for biomedical porous material based on its superior machinability, biocompatibility, biodegradation, bioresorbability, and so on. In this paper, we have reviewed the key features of SF. Moreover we have focused on the morphous, technical processing, and biocompatib...

Formation of yellow-red color cocoons in the silkworm, Bombyx mori, occurs as the result of the selective delivery of carotenoids from the midgut to the silk gland via the hemolymph. This process of pigment transport is thought to be mediated by specific cellular carotenoids carrier proteins. Previous studies indicated that two proteins, Cameo2 and CBP, are associated with the selective transpo...

Small ubiquitin-like modifier (SUMO) modification (SUMOylation) is an important and widely used reversible modification system in eukaryotic cells. It regulates various cell processes, including protein targeting, transcriptional regulation, signal transduction, and cell division. To understand its role in the model lepidoptera insect Bombyx mori, a recombinant baculovirus was constructed to ex...

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 cocoon...
