First report of a begomovirus associated with betasatellites infecting spinach (Spinacia oleracea) in India

Abstract

Spinach (Spinacia oleracea) leaves with vein yellowing and reduced leaf size were observed in Rasidpura, Rajasthan Province, India. The complete DNA-A and betasatellite sequences of the virus isolated from infected spinach leaves were determined and comprised 2,753 and 1,367 nucleotides, respectively. The sequence had the highest level of nucleotide sequence identity (88 %) with an isolate of Papaya leaf curl virus and likely represents a new species, for which we propose the name Spinach yellow vein Sikar virus. This is the first report of a Begomovirus associated with satellite molecules infecting the host S. oleracea in India.
