Double-Stranded RNA Injection Produces Null Phenotypes in Zebrafish

double-stranded rna viral infection in tehran trichomonas vaginalis isolates.

background : trichomonas vaginalis is a pathogenic protozoon and may be contaminated with dsrna virus called trichomonas vaginalis virus (tvv). the viral infection is an important factor for its patho-genesis and sensitivity to metronidazole. the presence of tvv is associated with qualitative and quantitative expression of cysteine proteinases and surface immunogenic; p270. the purpose of this ...

Double-stranded RNA poses puzzle.

Microglia Recognize Double-Stranded RNA

Inheritance of killer phenotypes and double-stranded RNA in Ustilago maydis.

Three different killer specificities in U. maydis are inherited cytoplasmically and transmitted by cell fusion. Each killer generates low frequencies of specifically immune forms in crosses with sensitive strains. The properties of immunity to each killer are also inherited cytoplasmically and transmitted by cell fusion. Killer strains carry virus-like particles about 41 nm in diameter. Each ki...

Expression of yeast L-A double-stranded RNA virus proteins produces derepressed replication: a ski- phenocopy.

The plus strand of the L-A double-stranded RNA virus of Saccharomyces cerevisiae has two large open reading frames, ORF1, which encodes the major coat protein, and ORF2, which encodes a single-stranded RNA-binding protein having a sequence diagnostic of viral RNA-dependent RNA polymerases. ORF2 is expressed only as a Gag-Pol-type fusion protein with ORF1. We have constructed a plasmid which exp...
