Figure 1

Genome Display Tool. The figure demonstrates some of the features of Genome Display Tool, described earlier. The green coloured cells represent the horizontal gene transfer events identified by Ochman et al [11] whereas the blue coloured cells represent the horizontal gene transfer events identified by Garcia and colleagues [12]. The red coloured cells are the genes which are predicted to have been horizontally transferred by both groups. The figure shows the genes on the forward strand with a '+' across them. It also shows the choice of five shapes available to the user to colour each cell. The user can choose to view information in the upstream or downstream region of the gene, if required.
