First report of Pepper vein yellow virus infecting hot pepper in Sudan.
In 2 successive winters (2009 and 2010), 14 hot pepper (Capsicum annuum) samples showing unusual symptoms were surveyed in permanently irrigated seasonal vegetable gardens along the Blue Nile in central Sudan (specifically in Gezira State). Symptoms included leaf curling, leaf deformation, reduced leaf size, leaf puckering, interveinal yellowing, vein clearing or yellow patches. The causal pathogen was identified as Pepper vein yellows virus (PeVYV) based on genetic (RT-PCR) analysis. This is thought to be the fFirst report of PeVYV infecting hot pepper in Sudan.
