Characterisation of Sri Lankan Cassava Mosaic Virus and Indian Cassava Mosaic Virus: Evidence for Acquisition of a DNA B Component by a Monopartite Begomovirus

Virology, 2002
Two bipartite begomoviruses, Indian cassava mosaic virus (ICMV) and Sri Lankan cassava mosaic virus (SLCMV), have been isolated from mosaic-diseased cassava originating from central India and Sri Lanka, respectively. ICMV was transmitted with low efficiency from cassava to Nicotiana benthamiana by sap inoculation to give leaf curl symptoms.

Sri Lankan cassava mosaic virusreplication associated protein (Rep) triggers transposition of IS426inAgrobacterium [PDF]

FEMS Microbiology Letters, 2014
We report a high rate of IS426 transposition in Agrobacterium tumefaciens in the presence of the Sri Lankan cassava mosaic virus (SLCMV) replication associated protein gene (Rep). Upon conjugal transfer of the binary plasmid pCam-SLCMV-Rep with the SLCMV Rep gene in the sense orientation under the transcriptional control of the Cauliflower mosaic virus
