A Novel Partitivirus That Confers Hypovirulence on Plant Pathogenic Fungi [PDF]
Journal of Virology, 2014 ABSTRACT Members of the family Partitiviridae have bisegmented double-stranded RNA (dsRNA) genomes and are not generally known to cause obvious symptoms in their natural hosts. An unusual partitivirus, Sclerotinia sclerotiorum partitivirus 1 (SsPV1/WF-1), conferred hypovirulence on ...

Natural Cross-Kingdom Spread of Apple Scar Skin Viroid from Apple Trees to Fungi
Cells, 2022 Viroids are the smallest known infectious agents that are thought to only infect plants. Here, we reveal that several species of plant pathogenic fungi that were isolated from apple trees infected with apple scar skin viroid (ASSVd) carried ASSVd ...

Hypovirulence and Double-Stranded RNA in Sclerotinia homoeocarpa [PDF]
Phytopathology®, 1997 One hundred and thirty-two isolates of Sclerotinia homoeocarpa, the causal agent of dollar spot of turfgrass, were evaluated for virulence on swards and detached leaves of creeping bentgrass and for the presence of double-stranded RNA (dsRNA). In at least four isolates, the hypovirulent phenotype was associated with the presence of specific segments ...

Mycovirus-induced hypovirulence in notorious fungi Sclerotinia: a comprehensive review
Brazilian Journal of Microbiology, 2023 Members of the genus Sclerotinia are notorious plant pathogens with a diverse host range that includes many important crops. A huge number of mycoviruses have been identified in this genus; some of these viruses are reported to have a hypovirulent effect on the fitness of their fungal hosts.
