Characterization of Rehmannia mosaic virus isolated from chili pepper ( Capsicum annuum ) in Japan

In 2010, severe necrotic mosaic disease and fruit distortion were observed on greenhouse-grown chili pepper (Capsicum annuum cv. Fushimi-amanaga) plants in Kyoto Prefecture, Japan. Electron microscopic imaging and genomic RNA sequencing indicated that the virus responsible was a new isolate of Rehmannia mosaic virus (ReMV), which had not been previously reported in Japan. Although ReMV systemically infected many Solanaceae species, including chili pepper and tomato (Solanum lycopersicum), tobamovirus-resistance genes from species of Capsicum (L 1a , L 2 , L 3 , and L 4 ) and tomato (Tm-1, Tm-2, and Tm-2 a ) conferred resistance against ReMV.
