First report of natural infection of Capsicum annuum by Tobacco streak virus in India.

Abstract

In February 2004, chilli (Capsicum annuum) samples exhibiting necrosis of leaves and buds were collected from farmers' fields around Faizabad, Uttar Pradesh, India, and were subjected to immunoassay. Comparative amino acid sequence analysis revealed that the virus infecting chilli shared very high levels of similarity at both nucleotide (98-99%) and amino acid (98%) levels, with the corresponding region of tobacco streak virus (TSV) isolated originating from multiple hosts and locations, suggesting that the virus infecting chilli is a strain of TSV and should be designated as TSV-CH. This is thought to be the first report of natural infection of chilli by TSV in northern India.
