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 کاملPlaque assay of nuclear polyhedrosis viruses in cell culture.
The nuclear polyhedrosis virus of Autographa californica has been titrated in Spodoptera frugiperda cells by the plaque method, using a solid overlay which does not require either the use of modified culture medium or expensive purified agarose or the addition of culture medium as a liquid layer above the solid agarose. This assay is more sensitive than that using a viscous methyl cellulose ove...
متن کاملExtensive nuclear DNA sequence diversity among chimpanzees.
Although data on nucleotide sequence variation in the human nuclear genome have begun to accumulate, little is known about genomic diversity in chimpanzees (Pan troglodytes) and bonobos (Pan paniscus). A 10,154-base pair sequence on the chimpanzee X chromosome is reported, representing all major subspecies and bonobos. Comparison to humans shows the diversity of the chimpanzee sequences to be a...
متن کاملCharacterization of the nucleotide sequence of the Lymantria dispar nuclear polyhedrosis virus DNA polymerase gene region.
The DNA polymerase gene of the Lymantria dispar multinucleocapsid nuclear polyhedrosis virus (LdMNPV) was cloned and sequenced. The predicted DNA polymerase protein (1113 amino acids, 115.9K) was found to have an amino acid identity of 48% with the corresponding gene of the Autographa californica MNPV (AcMNPV). It contains five domains associated with substrate binding, primase interaction, and...
متن کاملNuclear entry of DNA viruses
DNA viruses undertake their replication within the cell nucleus, and therefore they must first deliver their genome into the nucleus of their host cells. Thus, trafficking across the nuclear envelope is at the basis of DNA virus infections. Nuclear transport of molecules with diameters up to 39 nm is a tightly regulated process that occurs through the nuclear pore complex (NPC). Due to the enor...
