Phylogenetic dendrograms based upon alignments of the complete nucleotide sequences of the ChiLCV (a) or ToLCB (b) clones obtained from tobacco in Oman with selected begomovirus and betasatellite sequences obtained from the databases. Vertical branches are arbitrary, horizontal branches are proportional to calculated mutation distance. Values at nodes indicate percentage boot strap values (1000 replicates). Begomovirus acronyms used are Chilli leaf curl virus (ChLCV), Cotton leaf curl Gezira virus (CLCuGeV), Pepper leaf curl virus (PepLCV), Tomato leaf curl Liwa virus (ToLCLwV), Tomato leaf curl Sudan virus (ToLCSDV) and Tomato yellow leaf curl virus (TYLCV). The betasatellite acronyms used are Chilli leaf curl betasatellite (ChiLCB), Cotton leaf curl Multan betasatellite (CLCuMuB), Tomato leaf curl Bangladesh betasatellite (ToLCBDB), Tomato leaf curl betasatellite (ToLCB) and Tomato leaf curl Karnataka betasatellite (ToLCKB). The trees were arbitrarily rooted on the sequence Tomato pseudo-curly top virus (TPCTV; X84735), for the virus tree, and Ageratum yellow vein Singapore alphasatellite (AYVSGA; FJ956707), for the betasatellite tree, as outgroup. The database accession numbers are indicated in each case. The sequences originating from tobacco are indicated by bold text in each case. The geographical origins of ChiLCV and ToLCB sequences are indicated on the right in each case
