Pepper leaf curl virus (PepLCV) is a DNA virus from the genus Begomovirus and the family Geminiviridae. PepLCV causes severe disease especially in pepper ( Capsicum spp. ). It can be found in tropical and subtropical regions such as Thailand and India , but has also been detected in countries such as the United States and Nigeria .
