Abstract
Verbena 'Taylortown Red' plants showed virus-like mottling symptoms. Virus purifications disclosed the presence of elongated and spherical particles, evidence of mixed virus infections, whereas double-stranded RNA analysis revealed the presence of several bands absent in healthy plants. After shotgun cloning, three viruses were identified in 'Taylortown Red': Broad bean wilt virus-1, Coleus vein necrosis virus, and a previously undescribed potyvirus. Given the importance of verbena to the ornamental industry, we studied the viruses found in 'Taylortown Red' and, in this article, we present our findings on the new potyvirus, provisionally named Verbena virus Y (VVY). VVY belongs to the Potato virus Y subgroup in the genus Potyvirus, has solanaceous plants, including potato, as alternative hosts, and can be transmitted by a ubiquitous pest in the ornamental industry, the green peach aphid.
