It is imperative that molecular diversity studies be completed for the major viruses in the PNW region to improve our understanding of the spectrum of their variability for the development of improved diagnostic tools in order to be able to detect all the strains of a given virus and prevent their spread in PNW vineyards. Towards this goal, we will initially focus molecular diversity studies on GLRaV-2, GVA, GVB, GRSPaV, GFLV and ToRSV. We will extend these studies to other GLRaVs during the course of this project, if there is an indication of molecular variability among these viruses.
