Double-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...

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 under force and torque: similarities to and striking differences from double-stranded DNA.

RNA plays myriad roles in the transmission and regulation of genetic information that are fundamentally constrained by its mechanical properties, including the elasticity and conformational transitions of the double-stranded (dsRNA) form. Although double-stranded DNA (dsDNA) mechanics have been dissected with exquisite precision, much less is known about dsRNA. Here we present a comprehensive c...
