Figure 3

Gene order structure of the trw locus of Bartonella species. The trw genes of Bartonella species are collinear with the respective genes of plasmid R388, except for the multiple tandem gene duplications of trwL and trwJ-I-H, which are present in variable copy numbers in the different species. The copy number of amplified genes or segments of the trw locus of five Bartonella species is indicated within the boxes. The copy number trwJ and trwL displays a large degree of sequence variation.
