First report of Wisteria vein mosaic virus infecting Chinese Wisteria in Jiangsu Province in China

Wisteria vein mosaic virus (WVMV) is a member of the Potyvirus genus, and it has become a worldwide disease. This virus has been only reported in Beijing and Zhejiang Province in China. In May 2018, virus-like symptoms such as chlorosis, mottling, mosaic and narrowing were observed in Chinese Wisteria in Yangzhou City in Jiangsu Province in China. This isolation can infect the Nicotiana benthamiana by mechanical inoculation. Serological and molecular identifications confirmed the isolation of WVMV. Phylogenetic tree analyses suggest that WVMV appeared most closely related to soybean mosaic virus (SMV) and watermelon mosaic virus. To our knowledge, this is the first report of WVMV in Chinese Wisteria in Jiangsu Province in China.
