Abstract

Non-cucurbitaceous weed species shown to be natural hosts of Cucumber vein yellowing virus in south-eastern Spain.

Abstract

In the spring of 2001, leaf symptoms ranging from vein clearing to general leaf chlorosis were observed on weed species (Convolvulus arvensis, Malva parviflora, Sonchus oleraceus, S. asper and S. tenerrimus) commonly growing within or near commercial horticultural greenhouses in Spain. RT-PCR tests identified the causal organism as cucumber vein yellowing virus. Whitefly transmission technique confirmed that S. oleraceus is the natural host of the virus.
