Abstract:

The Tomato leaf curl New Delhi virus is an emerging disease of pumpkin associated with mosaic disease in central, India. Symptomatic pumpkin leaf samples from different locations in the Bhopal district were collected and confirmed for begomovirus disease by PCR using a begomovirus coat-protein gene-specific primer. All five samples were amplified, expecting ~800 bp of amplicons of associated begomovirus; these amplicons were purified and sequenced for identification of begomovirus species associated with mosaic disease on the pumpkin. The consensus nucleotide sequence data were submitted to the NCBI database under the accession numbers OQ320768, OQ320770, OQ320774, OQ116977, and OQ116978. The understudy begomovirus isolates showed the highest 95–97% nucleotide sequence identities and close phylogenetic relationships with several isolates of Tomato leaf curl New Delhi virus. To our knowledge, this was the first record of the Tomato leaf curl New Delhi virus associated with the mosaic disease of pumpkin in Central India.
