Complete genome sequence and phylogenetic relationships of tobacco streak virus causing groundnut stem necrosis disease in India.

ABSTRACT: Tobacco streak virus (TSV, genus Ilarvirus family Bromoviridae) is known to cause stem necrosis disease (SND) in groundnut (Arachis hypogaea) since 2000 in Southern India. The TSV isolate infecting groundnut so far has not been characterized based on the complete genome sequence. In this study, TSV was isolated from a naturally infecting groundnut plant in Kadiri, the hot-spot of the SND in southern India. During the Kharif season of 2014, groundnut plants in an experimental field were affected with chlorosis and necrosis in leaf, stem and buds. The cent percent of the 48 samples with these symptoms collected from the field tested positive for TSV in ELISA samples in this context. One isolate, GN-Kad was established from a single lesion on cowpea cv. C-152 throu
