A multipartite DNA virus was isolated from a plant pathogenic fungus, which is infectious as cloned and purified virions.
Abstract Mycovirus‐mediated hypovirulence has the potential to control fungal diseases. However, availability of hypovirulence‐conferring mycoviruses for plant disease is limited as most viruses are asymptomatic. In this study, virus‐induced gene silencing (VIGS) vector p26‐D4 Fusarium graminearum gemytripvirus 1 (FgGMTV1), a tripartite circular single‐stranded DNA mycovirus, successfully constructed convert causal fungus cereal head blight (FHB) into hypovirulent strain. p26‐D4, with an...
ABSTRACT The intricate interplay between mycoviruses and their fungal hosts frequently culminates in asymptomatic infections, but the virus-derived factors underlying these infections remain poorly understood. Our study introduces p18, a novel protein encoded by DNA-C segment of genomovirus FgGMTV1, which facilitates transition from virus-induced hypovirulence to infection within Fusarium graminearum upon its expression. We have confirmed expression p18 during FgGMTV1 observed presence both...
Abstract A novel negative-stranded RNA mycovirus was isolated from the phytopathogenic fungus Fusarium sibiricum strain AH32. This virus, tentatively named coguvirus 1 (FsCV1), has a bipartite genome consisting of two segments (RNA1 and RNA2). The negative-sense RNA1 is 6737 nt in length, encoding RNA-dependent polymerase (RdRp, p251) viral complementary (vc) strand. ambisense RNA2 (1232 long) encodes overlapping proteins: nucleocapsid protein (NP, p38) vc strand an unknown function (UFP,...
Abstract Nematodes are abundant, yet little is known about their viruses. In this study, we report a novel partitivirus isolated from Entomopathogenic nematode specie “ Steinernema ceratophorum , named as Partiti-like Virus 1 (ScPV1). The complete genome of ScPV1 comprised two dsRNA segments, dsRNA1 (2352 bp) and dsRNA2 (2196 in length. Both dsRNAs contained single open reading frame (ORF), encoding putative RNA-dependent RNA polymerase (RdRp) coat protein (CP), respectively. sequences the...
