Trypanosoma brucei AAT loci. 11 Chromosomes are arranged circularly and labelled by number in clockwise fashion. Dark shaded bars across chromosomes represent AAT loci and are labelled with locus number, GeneDB identifier and copy number (also reflected in the band width). Grey shaded bars represent the genomic positions of AAT loci found in L. major or T. cruzi, but absent in T. brucei, and are labelled inside the circle. The status of each AAT locus in L. major and T. cruzi is represented by red and black circles respectively; shaded circles indicate the presence of a homoeologous gene, open circles indicate the absence of any AAT gene, but with typically conserved synteny around the location.
