Figure 4

Evolution of the genomic architecture of tubulin loci in Kinetoplastida. (a) A Maximum likelihood phylogram of relationships among kinetoplastids, estimated from small subunit ribosomal RNA sequences (maximum of 2065 bp), with a GTR+I+Γ substitution model. Scale bar in substitutions per site. Values at nodes refer to non-parametric bootstrap values, out of 100. Terminal nodes are shaded according to their character state: alternating arrays (black) or monotypic arrays (white). The tree is rooted with bodonid sequences. (b) Cartoons of tubulin tandem arrays identified in kinetoplastids. Intergenic sequences are indicated with horizontal lines and include symbols referring to particular non-coding sequence motifs: polypurine tract (blue hexagon), polypyrimidine tracts (green circle), microsatellites (yellow triangle) and recognised cleavage signal (red star).
