1) Identify additional molecular markers linked with Ren4; 2) Genotype additional ARS-Parlier progeny segregating for Ren4 resistance to identify new recombinants; 3) Screen and sequence BAC library from Ren4 source vine to identify chromosome inserts containing or flanking Ren4; 4) Isolate candidate Ren4 resistance genes; 5) Test gene function in transient and stable expression systems to detect improved resistance.
