Neighbor-joining phylogenetic analysis. Using MEGA 4.0 of the complete genome of isolates of the West African tomato-infecting begomoviruses (WATIBs) and other begomovirus isolates from the NCBI GenBank. Arrows indicate other begomoviruses identified in West and Central Africa other than the WATIBs. Horizontal lines are in proportion to the number of nucleotide substitutions per site. Numbers represent percent bootstrap values out of 2,000 replicates. The GenBank accession numbers of the nucleotide sequences are indicated. The abbreviations are according to Brown et al. .
