The complete genome of a novel fungal virus, Puccinia striiformis narnavirus 1 (PsNV1), was sequenced and analyzed. The full-length cDNA sequence is 2340 bp in length with a GC content of 50.04%. PsNV1 contains a single open reading frame (ORF), which encodes a putative RNA-dependent RNA polymerase (RdRp) of 741 amino acids with a molecular mass of 81.8 kDa. RdRp phylogeny showed that PsNV1 grouped together with Fusarium poae narnavirus 1 (FpNV1) as a sister branch of narnaviruses, forming a… 


Complete genome sequence of a novel mitovirus from the wheat stripe rust fungus Puccinia striiformis
Phylogenetic analysis indicated that PsMV1 is a new member of the genus Mitovirus within the family Narnaviridae and the first report of the full-length nucleotide sequence of a novel mitovirus from the causal agent of wheat stripe rust.
Molecular Characterization of Novel Totivirus-Like Double-Stranded RNAs from Puccinia striiformis f. sp. tritici, the Causal Agent of Wheat Stripe Rust
The results demonstrate the presence of diverse, novel totiviruses in the P. striiformis field populations, and suggested that these novel viruses belong to the genus Totivirus in the family Totiviridae.
Multiple virus infection in a single strain of Fusarium poae shown by deep sequencing
Many bands were detected on an electrophoretic profile of double-stranded (ds) RNA preparation from a single strain of Fusarium poae isolated from wheat, finding the RNA virome of the strain was found to be highly diverse.
High genome heterozygosity and endemic genetic recombination in the wheat stripe rust fungus
The results show the effectiveness of the ‘ fosmid-to-fosmid’ strategy for sequencing dikaryotic genomes and the feasibility of genome analysis to understand race evolution in Pst and other obligate pathogens.
The family narnaviridae: simplest of RNA viruses.
Evidence for increased aggressiveness in a recent widespread strain of Puccinia striiformis f. sp. tritici causing stripe rust of wheat.
This research quantifies differences in aggressiveness among isolates representative of the pre-2000 and post-2000 populations to demonstrate that wheat rust fungi can adapt to warmer temperatures and cause severe disease in previously unfavorable environments.
Variation for isozymes and double‐stranded RNA among isolates of Puccinia striiformis and two other cereal rusts
Consistent differences in isozyme and dsRNA phenotype between the WYR and BYR isolates of P. striiformis indicate that these are two discrete populations, supporting the view that they should be recognized as f.
Global status of stripe rust: a review of historical and current threats
It was evident that Pst remains a significant threat in the majority of wheat growing regions of the world with potential to inflict regular regional crop losses ranging from 0.1 to 5%, with rare events giving losses of 5–25%.
