Cytoplasmic Polyhedrosis Virus of Bombyx mori
Two structurally different classes of oligonucleotides accumulate in vitro in cytoplasmic polyhedrosis virus (CPV) transcription mixtures in molar excess as compared to the completed RNA products. The first class consists of oligonucleotides which correspond to the 5’terminal sequence of the virus mRNAs (referred to as initiator oligonucleotides). The major species of initiator oligonucleotides...
متن کاملMolecular cloning and physical mapping of the genome of Bombyx mori nuclear polyhedrosis virus.
A restriction fragment library which covered the entire genome of Bombyx mori nuclear polyhedrosis virus (BmNPV) was constructed using plasmid vectors. By analysis of cloned and viral DNA by double digestion with endonucleases and by hybridization techniques, a complete physical map of BmNPV was constructed for BamHI, EcoRI, HindIII, KpnI, PstI and SmaI. Five regions of repeated sequences conta...
متن کاملDivergence and evolution of homologous regions of Bombyx mori nuclear polyhedrosis virus.
Homologous regions (hrs) (hr1,hr2-left,hr2-right,hr3,hr4-left,hr 4-right, and hr5) similar to those found in the Autographa californica nuclear polyhedrosis virus (AcNPV) genome were found in the Bombyx mori NPV (BmNPV) genome. The BmNPV hrs contained two to eight repeats of a homologous nucleotide sequence which were on average about 75 bp long. All of these homologous sequence repeats contain...
متن کاملBotanicals against Nuclear Polyhedrosis Virus infecting three breeds of mulberry silkworm, Bombyx mori L
Mulberry silkworm, Bombyx mori L, most valued for silk and other medicinal products is prone to various biotic stresses among which the disease caused by Nuclear Polyhedrosis Virus (BmNPV) is most serious as it occurs throughout the year causing losses to the tune of 30-40 per cent. Studies conducted on eco friendly management of the disease using botanicals revealed that 800 ppm hexane leaf ex...
متن کاملIdentification of an antiviral principle in Spirulina platensis against Bombyx mori Nuclear Polyhedrosis Virus (BmNPV)
Virus diseases in Bombyx mori, particularly the Nuclear Polyhedrosis Virus (NPV) account for 70-80% of the total loss and thus pose a major problem in sericulture. The NPV is characterized by having distinctive inclusion bodies either polyhedral or capsular in size, in which several virus particules are embedded. Spirulina has been found to inhibit the viral replication and strengthen both the ...
