First report of Tobacco mild green mosaic virus infecting Capsicum annuum in Tunisia.
During the springs of 2007 and 2008, leaf deformations as well as symptoms of mild green and chlorotic mosaic were observed on pepper (Capsicum annuum) plants grown in Monastir (northwest Tunisia) and Kebili (southeast Tunisia). Symptomatic leaf samples were analysed by transmission electron microscopy, and isolates were also subjected to ELISA and RT-PCR. The causal agent was identified as Tobacco mild green mosaic virus (TMGMV). Although C. annuum has been shown as a natural host of TMGMV, this is thought to be the first report of TMGMV in Tunisia.
