Nongenetic reactivation of frog virus 3 DNA

Virology, 1979
Abstract Fathead minnow cells co-infected with purified frog virus 3 DNA and either ultraviolet light-irradiated virus or a temperature-sensitive mutant at a nonpermissive temperature produced infectious progeny with the genotype of the purified DNA.

Localization of some frog virus 3 structural polypeptides

Virology, 1982
Abstract The localization of several frog virus 3 structural polypeptides has been established by stripping the different layers of the virion with controlled degradations using Brij, NP 40, and Pronase. The degradation products were further separated on sucrose gradients and characterized by electron microscopy and SDS-gel electrophoresis.

Amphibian ocular malformation associated with frog virus 3

The Veterinary Journal, 2008
During an on-going amphibian ecology study, a free-ranging American bullfrog (Rana catesbeiana) metamorph was captured in a pitfall trap adjacent to a constructed farm pond at the Plateau Research and Education Center (PREC) on the Cumberland Plateau near Crossville, Tennessee, USA.

A low resolution structure of frog virus 3

Virology, 1979
Abstract The structure of frog virus 3, a lipid containing deoxyribovirus, has been investigated with neutron scattering. A diameter of 1580 A is found, larger than previous estimation based on electron microscopy. The lipids are concentrated in a 40-A-thick layer at 85 A inside the virion. The virion is highly hydrated, mostly the large central core

Transcription of Frog Virus 3

1990
Frog virus 3 (FV3) genes are expressed in infected cells in an orderly stepwise fashion that resembles the pattern of temporal gene activation that occurs during cellular development. To carry out this sequential and quantitative regulation of transcription, FV3 produces a cascade of trans-acting regulatory proteins that (i) cause a switch-off of host ...

Arginine requirement for frog virus 3 development

Virology, 1975
Abstract Arginine-depleted BHK cells did not support the multiplication of Frog Virus 3 but allowed the replication of viral DNA. The recovery of the DNA in the nuclear fraction of the infected cells as well as its sensitivity to DNase led to the conclusion that a defect of the encapsidation process took place.

Restriction endonuclease mapping of the frog virus 3 genome

Virology, 1983
A physical map for the frog virus 3 (FV 3) genome was constructed after digestion with the following restriction endonucleases: EcoRI, HindIII, KpnI, and XbaI. Mapping of the DNA was accomplished by partial digestion and recutting, double-digestion, and Southern blot hybridization with deduction of overlaps. Although the virion DNA is physically linear,

Translation Regulation of Frog Virus 3

1989
Frog virus 3 (FV 3), the amphibian virus the most extensively analyzed belongs to the family Iridoviridae. The study of the multiplication cycle of this virus, isolated by Granoff et al (1966), has revealed several original features such as i) the replication occurs in the nucleus and the cytoplasm of the host cell, ii) the RNA polymerase II is ...

Transcriptional Regulation of Frog Virus 3

1989
Transcriptional regulation of eukaryotic promoters is now thought to be mediated by the interaction of specific trans— acting factors with cis-regulatory DNA sequences and RNA poly-merase II (Kingston et al., 1985). Large DNA viruses such as the iridovirus frog virus 3 (FV3) provide an excellent model system for the study of such regulatory processes ...

Interaction of Frog Virus 3 with the Cytoskeleton

1985
The eukaryotic cell contains a detergent-insoluble structural framework termed the cytoskeleton (Brown etal. 1976; Lenk etal. 1977; Osborn and Weber 1977; Webster et al. 1978). The principal components of the cytoskeleton are three chemically and morphologically distinct filaments: the microtubules, the intermediate filaments, and the microfilaments ...
