cDNA clones of the RSPaV viral strain and associated polypeptides and antibodies thereof

摘要

An isolated protein or polypeptide corresponding to a protein or polypeptide of a Rupestris stem pitting associated virus (RSPaV) is described. The encoding DNA molecule, either alone in isolated form, in an expression system, a host cell, or a transgenic grape plant, is also disclosed. Other aspects relate to a method of imparting Rupestris stem pitting associated virus resistance to grape plants by transforming them with the aforementioned DNA molecule, and a method of detecting the presence of a Rupestris stem pitting associated virus, such as RSPaV-1, in a sample.
