Abstract

First report of Plantago asiatica mosaic virus in Rehmannia glutinosa in Korea.

Abstract

In 2010, three R. glutinosa plants showing virus-like symptoms, namely chlorotic and necrotic local spots, vein necrosis and mosaic on the leaves, and stunting, were collected from a greenhouse in the Hwasun area of Korea. Electron microscopy and RT-PCR indicated that these plants were infected with three different viruses, Broad bean wilt virus 2 (BBWV2), Ribgrass mosaic virus (RMV), and an unknown filamentous rod virus (∼400 to 500 nm in length). In the present study, the filamentous rod virus was preliminarily confirmed to be a potexvirus by RT-PCR, using universal primers, and then characterized as Plantago asiatica mosaic virus (PlAMV) by sequence analysis of the amplified PCR products. PlAMV has a wide host range, and has been isolated from various plants such as Plantago asiatica, Primula sieboldii, Nandina domestica and Viola grypoceras, as well as from lily. This is thought to be the first report of PlAMV in R. glutinosa.
