Potato virus Y (PVY) is one of the oldest known plant viruses, and yet in the past 20 years it
emerged in the United States as a relatively new and very serious problem in potato. The …

To establish a successful infection plant viruses have to overcome a defense system
composed of several layers. This review will overview the various strategies plants employ …

The phytoene desaturase (PDS) gene of Nicotiana benthamiana was silenced in plants
infected with potato virus X (PVX) vectors carrying PDS inserts, and a green fluorescent …

▪ Abstract Nineteen single dominant genes (R genes) for resistance to viruses, nematodes,
and fungi have been positioned on the molecular map of potato using DNA markers …

In the past decade, various methods have been developed for the identification and typing of
prokaryotic and eukaryotic organisms at the DNA level. These methods differ in their …

Amplified fragment length polymorphism (AFLP) is a novel molecular fingerprinting
technique that can be applied to DNAs of any source or complexity. Total genomic DNA is …

The isolation of the nematode‐resistance gene Gpa2 in potato is described, and it is
demonstrated that highly homologous resistance genes of a single resistance‐gene cluster …

Sequence-characterized amplified regions (SCARs) were developed, based on nucleotide
differences within resistance gene-like fragments isolated from a potato plant carrying the Ry …

Genomic positions of phenotypically defined disease resistance genes (R genes) and R
gene homologues were analyzed in three solanaceous crop genera, Lycopersicon (tomato) …

A novel locus for extreme resistance to Potato virus Y (PVY), Ry-f sto, was identified on
potato chromosome XII. The gene Ry-f sto has been introgressed from the wild potato …
