چکیده
Purified cytoplasmic-polyhedrosis virus has been found to have associated with it a polymerase activity capable of catalyzing the synthesis of virus-specific, single-stranded ribonucleic acid (RNA) from the double-stranded RNA genome.

Purification and characterization of antiviral protein from silkworm fecal matter
Antiviral proteins (AVP), present in silkworm fecal matter, show activity against nuclear polyhedrosis virus (NPV) in vitro and in vivo. The extract of silkworm fecal matter prepared in phosphate buffer solution of pH 7.5 was subjected to 50% solid ammonium sulfate precipitation to enrich AVP, then which was dialyzed. The dialysate was applied to the column containing silica gel-G, the column e...
متن کاملSpecial Section: Recent Advances in Silkworm Biology
The silkworm, Bombyx mori is infected by a number of viruses: Bombyx mori nuclear polyhedrosis virus (BmNPV), cytoplasmic polyhedrosis virus (CPV), infectious flacherie virus (IFV) and densonucleosis virus (DNV). Except DNV, resistance of silkworms to the virus is controlled by polygenes. Serologically, two DNV types, DNV-1 and DNV-2 are identified. The non-susceptibility to DNV types is confer...
متن کاملMolecular cloning of a phosphotriesterase-related protein gene of silkworm and its expression analysis in the silkworm infected with Bombyx mori cytoplasmic polyhedrosis virus
Bombyx mori cytoplasmic polyhedrosis virus is one of the major viral pathogens for the silkworm. The immune response of silkworm to the virus infection is obscure. A phosphotriesterase-related protein gene of silkworm, Bombyx mori (BmPTERP) was found in our previous microarry analysis of the midgut infected with the virus. In the present study, we cloned and analyzed the full-length cDNA of BmP...
متن کاملCharacterization of 3'----5' exonuclease associated with DNA polymerase of silkworm nuclear polyhedrosis virus.
3'----5' Exonuclease specific for single-stranded DNA copurified with DNA polymerase of nuclear polyhedrosis virus of silkworm Bombyx mori (BmNPV Pol). BmNPV Pol has no detectable 5'----3' exonuclease activity on single-stranded or duplex DNA. Analysis of the products of 3'----5' exonucleolytic reaction showed that deoxynucleoside monophosphates were released during the hydrolysis of single-str...
متن کاملEffect of Salicylic Acid on Commercial Traits of the Bivoltine Crossbreed Races of the Silkworm, Bombyx mori L.
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 cocoo...
