Coordinate regulation of replication and virion sense gene expression in wheat dwarf virus.
We have investigated the relationship between viral DNA replication and virion sense gene expression in wheat dwarf virus (WDV), a member of the geminivirus group, by testing a series of deletion mutants in transfected Triticum monococcum (einkorn) protoplasts. Mutants contained a transcription fusion of the chloramphenicol acetyltransferase coding sequence to the virion sense promoter that rep...
متن کاملA sensitive method for the quantification of virion-sense and complementary-sense DNA strands of circular single-stranded DNA viruses
Circular single-stranded DNA (ssDNA) viruses are the smallest viruses known to infect eukaryotes. High recombination and mutation rates have conferred these viruses with an evolutionary potential that has facilitated their emergence. Their damaging effects on livestock (circoviruses) and crops (geminiviruses and nanoviruses), and the ubiquity of anelloviruses in human populations and other mamm...
متن کاملSpinach curly top virus: A Newly Described Curtovirus Species from Southwest Texas with Incongruent Gene Phylogenies.
ABSTRACT A curtovirus associated with a disease of spinach was isolated in southwest Texas during 1996. Disease symptoms included severe stunting and chlorosis, with younger leaves curled, distorted, and dwarfed. Viral DNA was purified and an infectious clone obtained. Agroinoculation using a construct bearing full-length tandem repeats of the cloned viral genome resulted in systemic infection ...
متن کاملSpecific Inhibition of the Expression of the Promyelocytic Leukemia (PML) Protein by Anti-Sense Oligonucleotides
In the present study, using anti-sense oligonucleotides the inhibition of expression of the PML protein hasbeen investigated. The anti-sense oligonucleotides were designed against the translation initiation site ofthe PML gene, and their effects were investigated on cellular growth and DNA synthesis. Incubation of normalhuman fibroblast cells with the anti-sense oligonucleotid...
متن کاملMutational analysis of the promoter required for influenza virus virion RNA synthesis.
An in vitro RNA synthesis system was established in which the influenza virus virion (minus-sense) RNA was made from the synthetic plus-sense RNA (cRNA) template by the purified viral polymerase complex. The cRNA promoter was studied by mutational analysis using the in vitro system, and on the basis of these experiments, the first 11 nucleotides of the 3' noncoding sequence were found to contai...
