A New Potyvirus sp. Infects Verbena Exhibiting Leaf Mottling Symptoms.

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.
