The complete nucleotide sequences of a monopartite begomovirus and an associated alphasatellite and betasatellite isolated from naturally infected okra (Abelmoschus esculentus) plants originating from Jordan were determined. The sequences of the begomovirus, alphasatellite, and betasatellites were determined to be 2,764, 1,307, and 1,354 nucleotides in length, respectively. Sequence Demarcation Tool (SDT) and phylogenetic analysis revealed that the begomovirus isolate shared the highest (99.5-99.8%) nt sequence identity with isolates of cotton leaf curl Gezira virus (CLCuGeV), a begomovirus found to exclusively infect cotton in Africa, and recently, in Asia and the Middle East. The DNA sequences of the alphasatellite and betasatellite exhibited the highest nt sequence identity (98.7-98.9% and 92.2-95.3%, respectively) to cotton leaf curl Gezira alphasatellite and cotton leaf curl Gezira betasatellite, respectively. This is the first identification of an African begomovirus, associated with DNA satellites, infecting okra in Jordan.
