First report of Pepino mosaic potexvirus in weeds
So far, only pepino (Solanum muricatum) and tomato (Lycospersicon esculentum) were reported as host plants of Pepino mosaic potexvirus (EPPO Alert List). Studies were done in Spain on possible other hosts which could act as reservoirs for the virus. 70 samples of plants were collected in Murcia and Canary Islands, and then tested: Amaranthus sp., A. viridis, Chenopodium murale, Convolvulus arvensis, Malva parviflora, Nicotiana glauca, Polypogon monspeliensis, Senecio vulgaris, Sisymbrium sp., Solanum nigrum and Sonchus oleraceus. The virus was detected in Amaranthus sp., M. parviflora, N. glauca, Solanum nigrum and Sonchus oleraceus. All weeds were asymptomatic, but symptoms could be reproduced by mechanically inoculating tomato plants with sap from these naturally infected plants. This is the first report of natural infections of Pepino mosaic potexvirus in weeds
