Marker-assisted selection in breeding silkworm strains with high silk production and resistance to the densonucleosis virus.
In the silkworm (Bombyx mori), resistance to the Zhenjiang (China) strain of the densonucleosis virus (DNV-Z) is controlled by the recessive gene nsd-Z (non-susceptible to DNV-Z), which is linked to 7 simple-sequence repeat markers. Marker-assisted evaluation and selection of DNV-Z-resistant silkworms were used for predicting DNV-resistance in backcrossed animals. A silkworm race was bred using...
متن کاملSusceptibility of three Eco-races of tropical Tasar silkworm to Antheraea mylitta cytoplasmic polyhedrosis virus (AmCPV)
Pathogenic infection in tasar silkworm, Antheraea mylitta Drury. is common and there is a breed specific response regarding tolerance. Observations reveal the possibility of differential response by haemocytes to microbial infection in different breeds. Hence, the susceptibility of three eco-races of tasar silkworm viz. Daba, Sarihan and Raily to Antheraea mylitta Cytoplasmic Polyhedrosis Virus...
متن کاملEngineering silkworms for resistance to baculovirus through multigene RNA interference.
Bombyx mori nucleopolyhedrovirus (BmNPV) that infects the silkworm, B. mori, accounts for >50% of silk cocoon crop losses globally. We speculated that simultaneous targeting of several BmNPV essential genes in transgenic silkworm would elicit a stable defense against the virus. We introduced into the silkworm germline the vectors carrying short sequences of four essential BmNPV genes in tandem,...
متن کاملApplication of Biometrical Genetics in Mulberry Silkworm Breeding: A Review
The silkworm, Bombyx mori is a lepidopteron insect by virtue of its economic importance for over a century has been used in many genetical experiments in several countries, especially China, India, Japan, Soviet Russia, Korea and many Southeast Asian and European countries. Many of the economic traits of this insect are known to be controlled by large number of polygenes. The silkworm varieties...
متن کاملFrom genome to proteome: great progress in the domesticated silkworm (Bombyx mori L.).
As the only truly domesticated insect, the silkworm not only has great economic value, but it also has value as a model for genetics and molecular biology research. Genomics and proteomics have recently shown vast potential to be essential tools in domesticated silkworm research, especially after the completion of the Bombyx mori genome sequence. This paper reviews the progress of the domestica...
