Identification of an RNA silencing suppressor from a plant double-stranded RNA virus.
RNA silencing is a mechanism which higher plants and animals have evolved to defend against viral infection in addition to regulation of gene expression for growth and development. As a counterdefense, many plant and some animal viruses studied to date encode RNA silencing suppressors (RSS) that interfere with various steps of the silencing pathway. In this study, we report the first identifica...
متن کاملDouble-stranded RNA mycovirus from Fusarium graminearum.
Double-stranded RNA (dsRNA) viruses in some fungi are associated with hypovirulence and have been used or proposed as biological control agents. We isolated 7.5-kb dsRNAs from 13 of 286 field strains of Fusarium graminearum isolated from maize in Korea. One of these strains, DK21, was examined in more detail. This strain had pronounced morphological changes, including reduction in mycelial grow...
متن کاملDouble stranded RNA virus in South African Trichomonas vaginalis isolates.
AIMS To screen Trichomonas vaginalis isolates from South Africa for the presence of a small double stranded RNA virus designated T vaginalis virus (TVV). METHODS TVV was detected by simultaneous extraction of DNA and RNA, and its presence confirmed by electron microscopy and nuclease digestions. RESULTS TVV was detected in 59 of 72 (81.9%) isolates. CONCLUSIONS These results indicate a po...
متن کاملDisruption of Specific RNA-RNA Interactions in a Double-Stranded RNA Virus Inhibits Genome Packaging and Virus Infectivity
Bluetongue virus (BTV) causes hemorrhagic disease in economically important livestock. The BTV genome is organized into ten discrete double-stranded RNA molecules (S1-S10) which have been suggested to follow a sequential packaging pathway from smallest to largest segment during virus capsid assembly. To substantiate and extend these studies, we have investigated the RNA sorting and packaging me...
متن کاملComplete genome sequence of a double-stranded RNA virus from avocado.
A number of avocado (Persea americana) cultivars are known to contain high-molecular-weight double-stranded RNA (dsRNA) molecules for which a viral nature has been suggested, although sequence data are not available. Here we report the cloning and complete sequencing of a 13.5-kbp dsRNA virus isolated from avocado and show that it corresponds to the genome of a new species of the genus Endornav...
