An endornavirus from a hypovirulent strain of the violet root rot fungus, Helicobasidium mompa.
The complete nucleotide sequence of a large double-stranded RNA (referred to as L1 dsRNA), previously identified as the hypovirulence factor from strain V670 of the violet root rot fungus, Helicobasidium mompa, is determined, marking the first report of a fungal endornavirus whose completeucleotide sequence has been determined.

Phylogenetic Analysis of Sugarcane Rusts Based on Sequences of ITS, 5.8 S rDNA and D1/D2 Regions of LSU rDNA
Phylogenetic analysis of sugarcane rusts based on sequences of ITS and the 5.8 S rDNA revealed two highly divergent ITS groups among isolates of Puccinia sp. sensu Muta, 1987 and P. kuehniiExpand
Diversity and vertical transmission of double-stranded RNA elements in root rot pathogens of trees, Helicobasidium mompa and Rosellinia necatrix.
Sexual reproduction functioned to remove dsRNA in both fungi since ds RNA was not detected from single sexual spore cultures, and possible explanations for the difference in the detection frequency are discussed in terms of the differences in their sexual reproduction and other factors. Expand
Hematologic characteristics and plasma chemistry values of juvenile loggerhead turtles from the ages of 1 mo to 3 yr were obtained and will aid in their medical management. Expand
Presence and distribution of double-stranded RNA elements in the white root rot fungus Rosellinia necatrix
Abstract Double-stranded (ds)RNA of various types was detected in 65 (21.8%) of 298 isolates from vegetative hyphae of Rosellinia necatrix by electrophoresis, but dsRNA was not detected from 39Expand
Nucleotide sequence of a mitochondrial RNA virus from the plant pathogenic fungus, Helicobasidium mompa Tanaka.
BLAST analysis indicates that the RDRP encoded by HmMV1-18 is more closely related to those encoded by mitochondrial viruses of some ascomycetes than to that of the unassigned RsM2-1A1 dsRNA in the basidiomycetous Rhizoctonia solani. Expand
Comparison between Rosellinia necatrix isolates from soil and diseased roots in terms of hypovirulence.
Results suggest that isolation of R. necatrix from soil is an effective method to obtain isolates with dsRNAs, including the hypovirulence factor, from Japan. Expand
Artificial Infection of Rosellinia necatrix with Purified Viral Particles of a Member of the Genus Mycoreovirus Reveals Its Uneven Distribution in Single Colonies.
RnMYRV-3 was transmissible from transfected strains to their respective, virus-free counterparts via hyphal anastomosis, and the level of virus accumulation varied among virus-transfected subcultures and within its single colonies, which may be ascribed to uneven viral distribution in single colonies and the difficulty in viral transmission to virus- free hyphae.

Appearance of mycovirus-like double-stranded RNAs in the white root rot fungus, Rosellinia necatrix, in an apple orchard.
Findings indicated that novel mycoviruses, from an unknown source, were infecting strains W563 and NW10 of R. necatrix in the soil, and that N10 dsRNA was being transmitted between incompatible strains, NW10 to W563. Expand
Evaluation of primer pairs for the reliable diagnosis of Paulownia witches'-broom disease using a polymerase chain reaction.
To establish a reliable method for detection of paulownia witches'-broom (PWB) phytoplasma by a polymerase chain reaction (PCR), several oligonucleotide primers that amplify ribosomal protein (rp) orExpand
