Occurrence of Grapevine leafroll-associated virus 1 in two ornamental grapevine cultivars in Washington State.

摘要

Samples of potted grapevines of Roger's Red, an interspecific hybrid between wild grape (Vitis californica, native to northern California) and the V. vinifera cv. Alicante Bouschet, and Claret Vine (V. vinifera cv. Purpurea Nana) showing dull green-to-scarlet bred leaves from 2 different nurseries in the Richland-Kennewick area and Prosser, WA, respectively. All samples tested positive only for Grapevine leafroll-associated virus 1. Results were further confirmed by nucleotide sequences comparison with isolates deposited in GenBank and by double antibody sandwich-ELISA. This is thought to be the first report of GLRaV-1 in 2 Vitis species distributed as ornamental grapes in Washington, USA.Digital Object Identifier http://dx.doi.org/10.1094/PDIS-01-11-0002
