Discussion paper: The naming of Potato virus Y strains infecting potato
This discussion paper proposes that any newly found isolates of PVY should be described within the context of the original strain groups based on the original methods of distinguishing strains, and sequence characterization of the complete genomes of isolates is highly recommended.
Organization of genes controlling disease resistance in the potato genome.
It is proposed that some QTL for resistance have a molecular basis similar to single R genes, and genes having structural similarity with cloned R genes and genes involved in the defense response are proposed.
Cassava Brown Streak Virus (Potyviridae) Encodes a Putative Maf/HAM1 Pyrophosphatase Implicated in Reduction of Mutations and a P1 Proteinase That Suppresses RNA Silencing but Contains No HC-Pro
Homology of CBSV HAM1 with cellular Maf/HAM1 pyrophosphatases suggests that it may intercept noncanonical nucleoside triphosphates to reduce mutagenesis of viral RNA.
Development of SCAR markers to the PVY resistance gene Ryadg based on a common feature of plant disease resistance genes.
Sequence-characterized amplified regions (SCARs) were developed, based on nucleotide differences within resistance gene-like fragments isolated from a potato plant carrying the Ryadg gene, which
Genetically distinct strains of Cassava brown streak virus in the Lake Victoria basin and the Indian Ocean coastal area of East Africa
Two genetically different and geographically separated populations of Cassava brown streak virus exist in East Africa.
Synergistic interactions of a potyvirus and a phloem-limited crinivirus in sweet potato plants.
It is hypothesized that SPCSV is able to enhance the multiplication of SPFMV in tissues other than where it occurs itself, perhaps by interfering with systemic phloem-dependent signaling required in a resistance mechanism directed against SP FMV.
Incidence of Viruses and Virus like Diseases of Sweetpotato in Uganda.
Logistic regression analysis revealed that co-infections of SPCSV with SPFMV and/or SPMMV were associated with more severe and persistent symptoms than infections with each of the viruses alone, suggesting that more viruses or viruslike agents are infecting sweetpotatoes in Uganda.
Complete Genome Sequence and Analyses of the Subgenomic RNAs of Sweet Potato Chlorotic Stunt Virus Reveal Several New Features for the Genus Crinivirus
The complete nucleotide sequences of genomic RNA1 and RNA2 of Sweet potato chlorotic stunt virus were determined, revealing that SPCSV possesses the second largest identified positive-strand single-stranded RNA genome among plant viruses after Citrus tristeza virus.
