Mutation of a Nicotiana tabacum L. eukaryotic translation-initiation factor gene reduces susceptibility to a resistance-breaking strain of Potato virus Y.

Abstract excerpt

Eukaryotic translation-initiation factors eIF4E and eIF(iso)4E in plants play key roles in infection by potyviruses and other plant RNA viruses. Mutations in the genes encoding these factors reduce susceptibility to the viruses, and are the basis of several recessive virus resistance genes widely used in plant breeding. Because virus variants occasionally break such resistance, the molecular basis for this...
