Symptomless grape plants (Vitis vinifera) cultivated in Jind, Punjab, have been found to carry a Grapevine red blotch virus (GRBV). Evaluation of full length DNA sequence (3204 bp) of the virus (KU522121) has revealed similarity with mastrevirus, begomovirus, and other Grapevine red blotch viruses reported in the US and Canada. Similar to naturally growing plants, agroinfiltrated model plants with infectious clone of GRBV do not show any visible disease warning sign. To the best of our knowledge, this is the first report of a symptomless host Vitis vinifera from Indian vineyards harbouring a Grapevine geminivirus.
