Figure 3

Schematic representation of the organisation of vkr genes. Coding sequences of genes selected in the different groups of organisms are represented. Boxes indicate respectively the positions of VFT, TM or TK domains. For each gene, arrows indicate the presence of introns at conserved positions either in several phyla (red arrows) or inside of a given phylum (black arrows). Grey arrows indicate the presence of introns at non conserved positions.
