Sri Lankan cassava mosaic virus (SLCMV) is a bipartite begomovirus infecting cassava in India and Sri Lanka. We have used Agrobacterium-mediated inoculation (agroinoculation) of cloned SLCMV DNA to inoculate additional hosts, Nicotiana tabacum and Arabidopsis. Although SLCMV infection in these hosts caused stunting, leaf deformation and developmental abnormalities, accumulation levels of viral DNA in the infected plants suggested that this virus was poorly adapted to them. In the natural host, cassava, agroinoculation produced infection at a low frequency. The monopartite nature of SLCMV, reported earlier in N. benthamiana, was maintained in the new hosts as well as in cassava.
