Novel polymycoviruses are encapsidated in filamentous virions.

ABSTRACT: Polymycoviridae is a relatively new viral family that was established nearly 5 years ago, but their viral morphologies (naked or encapsidated) remain controversial since only one member namely, Colletotrichum camelliae filamentous virus 1 (CcFV1), was identified as being encapsidated in filamentous virions. Here, three novel double-stranded RNA (dsRNA) viruses belonging to the family Polymycoviridae were identified in three phytopathogenic fungal strains and tentatively named Pseudopestalotiopsis camelliae-sinensis polymycovirus 1 (PcsPmV1), and Phyllosticta capitalensis polymycovirus 1 and 2 (PhcPmV1 and 2), respectively. PcsPmV1 and PhcPmVs have five or six genomic dsRNAs, ranging from 1,055 to 2,405 bp, encoding five or seven putative open reading fram
