Complete genome sequence of a novel mitovirus from the wheat stripe rust fungus Puccinia striiformis
Archives of Virology 164 (3), 897-901
Abstract: The complete genome of a novel mycovirus, Puccinia striiformis mitovirus 1 (PsMV1), derived from the wheat stripe rust fungus Puccinia striiformis strain SCSN-10, was sequenced and analyzed. The full-length cDNA sequence is 2496 bp in length with a predicted AU content of 57.65% in the genomic RNA. Sequence analysis indicated that a single large open reading frame (ORF) is present on the positive strand when the fungal mitochondrial genetic code is used. The single ORF encodes a putative RNA-dependent RNA polymerase of 743 amino acids with a molecular mass of 84.9 kDa that shares the closest similarity with the corresponding proteins of Cronartium ribicola mitovirus 5 and Helicobasidium mompa mitovirus 1-18 (34% and 35% aa sequence identity, respectively). Phylogenetic analysis further indicated that PsMV1 is a new member of the genus Mitovirus within the family Narnaviridae. This is the first report of the full-length nucleotide sequence of a novel mitovirus, PsMV1, from the causal agent of wheat stripe rust.
