First outbreak of Pepper vein yellows virus infecting sweet pepper in Italy.
In October 2015, severe symptoms not previously reported by growers in the horticultural area of the province of Trapani (Sicily, Italy) were observed on sweet pepper plants in 8 different greenhouses. Symptoms included upward leaf curling, internodal shortening and interveinal yellowing. Symptoms were more evident in the upper part of the plants. These symptoms were reminiscent of those caused by poleroviruses. In the greenhouse, symptoms were evident in approximately 35% of the plants. Three samples per greenhouse (24 in total) were collected for analysis. The causal pathogen was identified as Pepper vein yellows virus (PeVYV) based on various molecular analyses. This is thought to be the first report of PeVYV infecting sweet pepper in Italy.
