Figure 4.

Venn diagram showing a comparison of three different Desulfotomaculum genomes, D. ruminis DSM 2154^T, D. acetoxidans DSM 771^T and D. nigrificans DSM 564^T. The number of overlapping protein genes is given inside the areas of the circles and the total number of derived protein sequences used for each strain is shown in parentheses. The figure was created using the program Venn diagram plotter available from the Pacific Northwest National Laboratory Software Distribution Center [51].
