Replication of baculovirus DNA.
The Baculoviridae is a diverse family of pathogens that are infectious for arthropods and are characterized by a complex replication cycle that culminates in the occlusion of virions in a crystalline protein matrix (Blissard & Rohrmann, 1990). Over 400 lepidopteran species serve as hosts for these viruses, with a single virus isolate usually restricted to one or a few related species. In additi...
متن کاملBaculovirus replication factor LEF-1 is a DNA primase.
The baculovirus replication factors LEF-1 and LEF-2 of the Autographa californica multinucleocapsid nucleopolyhedrovirus were overexpressed as fusions containing a hemagglutinin (HA) epitope and a HIS(6) tag using recombinant baculoviruses. LEF-1 was purified to near homogeneity and found to have primase activity in an indirect assay employing Escherichia coli DNA polymerase I (Klenow enzyme) a...
متن کاملP34.8 (GP37) is not essential for baculovirus replication.
Previous reports have indicated that p34.8 (gp37) may be essential for the replication of Autographa californica nucleopolyhedrovirus (AcMNPV) because no virus with inactivated p34.8 was isolated. We have ascertained the requirement for this gene by attempting to inactivate it with a large insertion [the gene encoding GFP (green fluorescent protein)] or by deleting all the conserved domains fro...
متن کاملBaculovirus lef-12 is not required for viral replication.
The baculovirus lef-12 (orf41) gene is required for transient expression of baculovirus late genes. To analyze the role of LEF-12 in the context of infected cells, two mutant viruses were constructed. Both mutants were viable in Trichoplusia ni High 5 and Spodoptera frugiperda Sf9 cells. Single-step growth curves, however, indicated that virus yields were reduced approximately fivefold in the a...
متن کاملBaculovirus replication in a mosquito (dipteran) cell line.
The baculovirus from the lepidopteran host Autographa californica (alfalfa looper) was shown to replicate in a dipteran cell line without the production of characteristic polyhedral inclusion bodies. The low level of replication could not be detected by 50% tissue culture infective dose titrations, but was apparent by [3H]thymidine labeling of the viral genome. Immunoprecipitation of the radioa...
