A novel partitivirus that confers hypovirulence on plant pathogenic fungi.
UNLABELLED 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 its natural plant-pathogenic fungal host, Sclerotinia sclerotiorum strain WF-1. Cellular organelles, including m...
متن کاملHypovirulence of the phytopathogenic fungus Botryosphaeria dothidea: association with a coinfecting chrysovirus and a partitivirus.
UNLABELLED Botryosphaeria dothidea is an important pathogenic fungus causing fruit rot, leaf and stem ring spots and dieback, stem canker, stem death or stool mortality, and decline of pear trees. Seven double-stranded RNAs (dsRNAs; dsRNAs 1 to 7 with sizes of 3,654, 2,773, 2,597, 2,574, 1,823, 1,623, and 511 bp, respectively) were identified in an isolate of B. dothidea exhibiting attenuated g...
متن کاملA geminivirus-related DNA mycovirus that confers hypovirulence to a plant pathogenic fungus.
Mycoviruses are viruses that infect fungi and have the potential to control fungal diseases of crops when associated with hypovirulence. Typically, mycoviruses have double-stranded (ds) or single-stranded (ss) RNA genomes. No mycoviruses with DNA genomes have previously been reported. Here, we describe a hypovirulence-associated circular ssDNA mycovirus from the plant pathogenic fungus Scleroti...
متن کاملMolecular Characterization of a Novel Putative Partitivirus Infecting Cytospora sacchari, a Plant Pathogenic Fungus
Three double-stranded RNAs (dsRNAs), approximately 1.85, 1.65 and 1.27 kb in size, were detected in an isolate of Cytospora sacchari from Iran. Partial nucleotide sequence revealed a 1,284 bp segment containing one ORF that potentially encodes a 405 aa protein. This protein contains conserved motifs related to RNA dependent RNA polymerases (RdRp) that showed similarity to RdRps of partitiviruse...
متن کاملMycoviruses and their role in biological control of plant diseases
Mycoviruses are the viruses that infect fungi and prevalent in all major groups of plant pathogenic and edible fungi. The first mycovirus was reported in 1962 from the cultivated mushroom (Agaricus bisporus); the infected mushrooms developed malformed fruiting bodies, grow slowly, mature early and resulting in serious yield losses. Although the majority of known mycoviruses have dsRNA genomes t...
