Association of Cotton leaf curl Multan virus and its associated betasatellite with leaf curl disease of Hibiscus rosa-sinensis in India.
In September 2011, symptoms of severe leaf curling, vein thickening and enation were observed on 31% (13/42) hibiscus (Hibiscus rosa-sinensis) plants grown in a garden at Lucknow, Uttar Pradesh, India. The symptoms and whitefly infestation suggested a begomovirus infection. Leaf samples from 13 diseased and 4 healthy hibiscus plants were collected. The causal pathogen was identified as Cotton leaf curl Multan virus (CLCuMV) and its associated betasatellite, Cotton leaf curl Multan betasatellite (CLCuMB), based on various molecular analyses. This is thought to be the first report of CLCuMV and CLCuMB on hibiscus in India.
