First report of a begomovirus and associated betasatellite in Rosa indica and in India

Abstract

The complete genome sequences of a begomovirus and associated betasatellite was obtained by the rolling circle amplification from rose (Rosa indica) exhibiting dwarfing, leaf distortion and leaf curling symptoms from Rajasthan, India. The sequence of the begomovirus was determined to be 2,741 bp and showed the typical genome arrangement of an monopartite Old World begomovirus. The sequence showed the highest nucleotide sequence identity (98 %) to an isolate of Rose leaf curl virus (RoLCuV), confirming it as an isolate of RoLCuV. The sequence of the rose begomovirus associated betasatellite (1,349 bp) displayed greater than 97 % nucleotide sequence identity to Digera leaf curl betasatellite. Our analysis also demonstrated that recombination events shaped the evolutionary history of RoLCuV. To our knowledge, this is the first report of RoLCuV associated with betasatellite infecting rose in India.
