Nucleotide sequence of the polyhedrin gene region of Helicoverpa zea single nucleocapsid nuclear polyhedrosis virus: placement of the virus in lepidopteran nuclear polyhedrosis virus group II.
The polyhedrin gene (polh) of Helicoverpa zea single nucleocapsid nuclear polyhedrosis virus (HzSNPV) was identified and shown by sequence analysis of the EcoRI I genomic fragment to encode a 246 amino acid polypeptide that has greater than 80% sequence identity to known polyhedrins. It is preceded by an AT-rich region containing the conserved late promoter motif TAAG, which was identified as a...
متن کاملThe Anticarsia gemmatalis nuclear polyhedrosis virus polyhedrin gene region: sequence analysis, gene product and structural comparisons.
The genomic region of the Anticarsia gemmatalis multiple nucleocapsid nuclear polyhedrosis virus (AgMNPV) strain 2D encoding the polyhedrin gene was cloned and mapped, and a 2085 bp SphI-PstI fragment containing the gene was sequenced. The polyhedrin polypeptide of the parental isolate AgMNPV was manually sequenced, and the amino acid sequence obtained agreed with that deduced from the DNA codi...
متن کاملCharacterization of nuclear polyhedrosis virus DNAs.
The nuclear polyhedrosis virus DNAs characterized and compared in this study consist of the singly-enveloped nucleocapsids (SNPV) of Trichoplusia ni and the bundles of nucleocapsids common to a single envelope (MNPV) from Spodoptera frugiperda and Rachiplusia ou. The SNPV and MNPV DNAs are very similar in hydrodynamic properties and molecular weights. In addition, the NPV DNAs are similar in si...
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 کاملVirus envelope acquisition of nuclear polyhedrosis virus in vitro.
There have been several reports concerned with the replication and morphogenesis of insect baculoviruses during the past decade [1--7]. While there is general agreement as to the assembly of the virus on the basis of electron microscopic studies, there are still questions regarding the details of the replicative mechanisms, such as the acquisition of the virus envelope. Three possible ways have...
