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 کاملA new double-stranded RNA binding protein (DRBP-120) is associated with double-stranded RNA-activated protein kinase (PKR).
Double-stranded RNA-activated protein kinase (PKR) plays an important role in interferon-induced antiviral responses, and is also involved in intracellular signaling pathways, including the apoptosis, proliferation, and transcription pathways. In this study, a new 120-kDa PKR-associated protein designated double-stranded RNA binding protein (DRBP)-120 was identified using co-immunoprecipitation...
متن کاملThe core of bluetongue virus binds double-stranded RNA.
Double-stranded RNA (dsRNA) viruses conceal their genome from the host to avoid triggering unfavorable cellular responses. The crystal structure of the core of one such virus, bluetongue virus, reveals an outer surface festooned with dsRNA. This may represent a deliberate strategy to sequester dsRNA released from damaged particles to prevent host cell shutoff.
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...
