Hemolin, an immunoglobulin-like protein, is involved in the immunity and development of Lepidoptera, but its exact functions are still unclear. In this work, the quantitative PCR and Western blot analysis were used to study the effects of exogenous substances on hemolin transcription and translation in the silkworm midgut. Also, RNA interference was used to examine the effects of hemolin on win...
The aim of this research was to estimate the variance components and genetic parameters for silkworm cocoon traits using univariate and multivariate models, and comparison of average productivity and resistance traits among three different selection strategies in two commercial silkworm lines of 153 and 154. Genetic parameters of cocoon weight, cocoon shell weight and cocoon shell percenta...
We report a draft sequence for the genome of the domesticated silkworm (Bombyx mori), covering 90.9% of all known silkworm genes. Our estimated gene count is 18,510, which exceeds the 13,379 genes reported for Drosophila melanogaster. Comparative analyses to fruitfly, mosquito, spider, and butterfly reveal both similarities and differences in gene content.
The infection of Bombyx mori nucleopolyhedrovirus (BmNPV) in silkworms is often lethal. It is difficult to prevent, and its lethality is correlated with both viral particle characteristics and silkworm strains. Low doses of titanium dioxide nanoparticles (TiO2 NPs) can promote silkworm growth and improve its resistance to organophosphate pesticides. In this study, TiO2 NPs' effect on BmNPV resi...
mulberry (morus spp.) is a perennial tree cultivated for its foliage to rear the domesticated silkworm, bombyx mori l. mulberry has improved through conventional breeding in general aims to improve the quantity and quality of leaf yield, which have direct bearing on silk productivity. leaf senescence is one of the major constraints, which restricts the quantity of quality leaf availability for ...
Oral supplementation with potassium bromide (10, 20 and 40 μg/ml) to fifth instar larvae of CSR2, CSR4 and CSR2xCSR4 crossbreed races of the silkworm, Bombyx mori resulted in a significant increase in the fat body glycogen in all the treated groups and in all the three races of the silkworm, B. mori. The fat body protein content was increased with 20 and 40 μg/ml treated groups in CSR2 and CSR4...
Human growth hormone (hGH) is a peptide hormone secreted by eosinophils of the human anterior pituitary, and a regulatory factor for a variety of metabolic pathways. A 30-kD protein from the pupa stage of silkworm was detected by Western blotting and confirmed by immunoprecipitation based on its ability to bind to anti-hGH antibody. This protein, named BmhGH-like protein, was purified from fres...
Silkworm pupae (Bombyx mori) are a high-protein nutrition source consumed in China since more than 2 thousand years ago. Recent studies revealed that silkworm pupae have therapeutic benefits to treat many diseases. However, the ability of the compounds of silkworm pupae to inhibit tumourigenesis remains to be elucidated. Here, we separated the protein of silkworm pupae and performed alcalase hy...
