Coordinate regulation of replication and virion sense gene expression in wheat dwarf virus.

Cloning and Expression of the Coat Protein Gene of Barley Yellow Dwarf Virus-PAV in Escherichia coli

Barley yellow dwarf virus: Luteoviridae or Tombusviridae?

UNLABELLED Summary Barley yellow dwarf virus (BYDV), the most economically important virus of small grains, features highly specialised relationships with its aphid vectors, a plethora of novel translation mechanisms mediated by long-distance RNA interactions, and an ambiguous taxonomic status. The structural and movement proteins of BYDV that confer aphid transmission and phloem-limitation pro...

The Effect of Herpes Simplex Virus Virion Host Shutoff Gene- a New Suicide Gene- on Tumor Cells

Background: The herpes simplex virus (HSV) UL41 gene product, virion host shutoff (Vhs) protein, mediates the rapid degradation of both viral and cellular mRNA. This ability suggests that Vhs protein can be used as a suicide gene in cancer gene therapy applications. The recent reports have shown that the degradation of cellular mRNA during herpes simplex infection is selective. RNA containing A...

Varicella Zoster Virus (VZV) Origin-Dependent Plasmid Replication in the Presence of the Four Overlapping Cosmids Comprising the Complete Genome of VZV

The Varicella-Zoster Virus (VZV) genome contains both cis-acting and trans-acting elements, which are important in viral DNA replication. The cis-acting elements consist of two copies of oriS, and the trans-acting elements are those genes whose products are required for virus DNA replication. It has been shown that each of the seven genes required for ori-dependent DNA synthesis of Herpes Simpl...

Wheat dwarf virus vectors replicate and express foreign genes in cells of monocotyledonous plants.

Wheat dwarf virus (WDV) is a geminivirus that infects monocotyledonous plants. To exploit the potential of WDV as a replicative gene vector, we developed a transient replication and expression system based on the transfection of protoplasts derived from Triticum monococcum suspension culture cells. Cloned genomic copies of various WDV isolates as well as mutants constructed in vitro were introd...
