Organization of the genomic DNA of the PA98-1-1 (black) and PA10-3 (gray) isolates of ToLDeV cloned from plants with symptoms of tomato leaf curl disease collected in Peru in 1998 and 2010, respectively. The IR and viral genes, including V1, C1, C2, and C3, predicted to express the CP, Rep, transactivator (TrAP), and replication enhancer (REn) proteins, respectively, are shown. Chimeras generated between the genomic DNAs of these isolates by exchanging an approximately 1.5-kb EcoRV/KpnI fragment with the IR and C4 and C1 genes are shown beneath the line.
