First report of Tobacco mosaic virus infecting Geranium thunbergii in Korea.

Abstract

Geranium thunbergii (Family Geraniaceae) forms a component of several popular folk medicines in Asia, including a traditional antidiarrheal drug. During a survey in July 2018, viral infection-like symptoms, including mosaic, mottling, and foliage discoloration were observed on the leaves of G. thunbergii in a farm located in Naju, Korea. Based on the results of DAS-ELISA, RT-PCR, sequence analysis and virulence testing, the causal agent was identified as tobacco mosaic virus (TMV). This is thought to be the first report of TMV infection affecting quality of G. thunbergii in Korea.
