Abstract
Codiaeum variegatum (common name, garden croton) is an ornamental plant grown for its bright yellow variegated leaf morphology. Two C. variegatum plants with upward leaf curling and vein swelling symptoms were collected in Faisalabad, Pakistan. Sequencing of clones obtained by PCR amplification with specific primers showed one plant infected with the monopartite begomoviruses pedilanthus leaf curl virus (PeLCV) and papaya leaf curl virus (PaLCuV) and the other to be infected with only PeLCV. Both plants also harboured a betasatellite that was distinct from all previously identified betasatellites, for which the name “codiaeum leaf curl betasatellite” (CoLCuB) is proposed. This is the first identification of a begomovirus and an associated betasatellite infecting C. variegatum in Pakistan. Both PeLCV and PaLCuV cause problems in a number of crop plants, and C. variegatum may act as a reservoir for these agriculturally important viruses. The precise impact and geographical distribution of the newly identified CoLCuB will be investigated.
