During a survey of viruses of groundnut in South Africa, tobacco streak virus (TSV) was detected in two groundnut plants at two different localities during different seasons in the North-West Province. Symptoms of the original field-collected samples included reduced young leaves with malformation and chlorotic patches. Older leaves had very mild chlorotic ringspots. The virus was isolated from the first accession by two local lesion transfers to Chenopodium quinoa. The isolate was inoculated onto groundnuts where the original symptoms were reproduced. Serology and sequencing of partial clones of the isolate confirmed it as tobacco streak virus. This is the first report of TSV on groundnuts in South Africa.
