Biological and Genetic Characterization of Potato Virus Y Isolates Affecting the U.S. Seed Potato Crop
Grant
Overview
abstract
State seed certification agencies are responsible for the collection of tubers and the initial serological testing to determine PVY and PVYN infection. Further characterization of up to 1000 isolates representing isolates from all seed producing states will include bioassays on tobacco and potato to determine if the virus causes necrosis, additional serological characterization and sequencing of genes known to be diagnostic for genetic and taxonomic classification.
