Genetic evidence for an essential role for potyvirus CI protein in cell-to-cell movement

Autor: Patricia E. Jensen, James C. Carrington, Mary C. Schaad

Publikováno v: The Plant Journal. 14:393-400

The potyvirus cylindrical inclusion (CI) protein, an RNA helicase required for genome replication, was analyzed genetically using alanine-scanning mutagenesis. Thirty-one mutations were introduced into the CI protein coding region of modified tobacco

VPg of tobacco etch potyvirus is a host genotype-specific determinant for long-distance movement

Autor: Andrew D. Lellis, Mary C. Schaad, James C. Carrington

Publikováno v: Journal of Virology. 71:8624-8631

The V20 cultivar of Nicotiana tabacum was shown previously to exhibit a strain-specific restriction of long-distance movement of tobacco etch potyvirus (TEV). In V20, both TEV-HAT and TEV-Oxnard strains are capable of genome amplification and cell-to

Suppression of long-distance movement of tobacco etch virus in a nonsusceptible host

Autor: James C. Carrington, Mary C. Schaad

Publikováno v: Journal of Virology. 70:2556-2561

To investigate host functions involved in the tobacco etch potyvirus (TEV) infection process, a tobacco line (V20) with a strain-specific defect in supporting systemic infection was analyzed. Using a modified TEV encoding a reporter protein, beta-glu

Genetics of mouse hepatitis virus transcription: evidence that subgenomic negative strands are functional templates

Autor: Mary C. Schaad, Ralph S. Baric

Publikováno v: Journal of Virology. 68:8169-8179

Mouse hepatitis virus (MHV) A59 temperature-sensitive (ts) mutants belonging to complementation group C were characterized and mapped by standard genetic recombination techniques. Temperature shift experiments early in infection suggested that the gr

Evidence for New Transcriptional Units Encoded at the 3′ End of the Mouse Hepatitis Virus Genome

Autor: Mary C. Schaad, Ralph S. Baric

Publikováno v: Virology. 196:190-198

Prior studies have demonstrated that the mouse hepatitis virus (MHV) genome is divided into at least seven coding regions each transcribed into a distinct mRNA. The majority of these mRNAs are synthesized from a highly conserved intergenic start site

Establishing a genetic recombination map for murine coronavirus strain A59 complementation groups

Autor: Stephen A. Stohlman, Kaisong Fu, Ralph S. Baric, Mary C. Schaad

Publikováno v: Virology

MHV-A59 temperature-sensitive mutants, representing one RNA+ and five RNA− complementation groups, were isolated and characterized by genetic recombination techniques. Maximum recombination frequencies occurred under multiplicities of infection gre

Functional Analysis of the Interaction between VPg-Proteinase (NIa) and RNA Polymerase (NIb) of Tobacco Etch Potyvirus, Using Conditional and Suppressor Mutants

Autor: James C. Carrington, Mary C. Schaad, José-Antonio Daròs

The tobacco etch potyvirus (TEV) RNA-dependent RNA polymerase (NIb) has been shown to interact with the proteinase domain of the VPg-proteinase (NIa). To investigate the significance of this interaction, a Saccharomyces cerevisiae two-hybrid assay wa

Long-distance movement factor: a transport function of the potyvirus helper component proteinase

Autor: James C. Carrington, Jeanmarie Verchot, Mary C. Schaad, Stephen Cronin, Ruth Haldeman-Cahill

Transport of viruses from cell to cell in plants typically involves one or more viral proteins that supply dedicated movement functions. Transport from leaf to leaf through phloem, or long-distance transport, is a poorly understood process with requi

Evidence that MHV Subgenomic Negative Strands are Functional Templates

Autor: Mary C. Schaad, Ralph S. Baric

Publikováno v: Advances in Experimental Medicine and Biology ISBN: 9781461357759

The genome of mouse hepatitis virus (MHV) is transcribed into a full length (~32 kb) and 6–8 subgenomic length mRNAs upon entry into susceptible cells1. Several discontinuous transcription models have been proposed to explain the presence of leader
