چکیده
We describe here a double-stranded RNA mycovirus, termed Fusarium graminearum alternavirus 1 (FgAV1/AH11), from the isolate AH11 of the phytopathogenic fungus F. graminearum Phylogenetic analysis showed that FgAV1/AH11 belongs to a newly proposed family, Alternaviridae This is the first report of a mycovirus in the family Alternaviridae that infects F. graminearum.

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...
متن کاملMolecular Characterization of a Novel Positive-Sense, Single-Stranded RNA Mycovirus Infecting the Plant Pathogenic Fungus Sclerotinia sclerotiorum
Recent studies have demonstrated that a diverse array of mycoviruses infect the plant pathogenic fungus Sclerotinia sclerotiorum. Here, we report the molecular characterization of a newly identified mycovirus, Sclerotinia sclerotiorum fusarivirus 1 (SsFV1), which was isolated from a sclerotia-defective strain JMTJ14 of S. sclerotiorum. Excluding a poly (A) tail, the genome of SsFV1 comprises 77...
متن کاملTwo Novel Relative Double-Stranded RNA Mycoviruses Infecting Fusarium poae Strain SX63
Two novel double-stranded RNA (dsRNA) mycoviruses, termed Fusarium poae dsRNA virus 2 (FpV2) and Fusarium poae dsRNA virus 3 (FpV3), were isolated from the plant pathogenic fungus, Fusarium poae strain SX63, and molecularly characterized. FpV2 and FpV3, with respective genome sequences of 9518 and 9419 base pairs (bps), are both predicted to contain two discontinuous open reading frames (ORFs),...
متن کاملComplete Genome Sequence of a Novel Hypovirus from the Phytopathogenic Fungus Fusarium langsethiae
We describe a novel positive single-stranded RNA virus, termed Fusarium langsethiae hypovirus 1 (FlHV1), from the isolate AH32 of the phytopathogenic fungus Fusarium langsethiae The properties of FlHV1 permit assignment to the genus Alphahypovirus in the family Hypoviridae This is the first report of a mycovirus identified in F. langsethiae.
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...
