Figure 1From: Tandem gene arrays in Trypanosoma brucei: Comparative phylogenomic analysis of duplicate sequence variationMixed patterns of variation within array Tb109c (hypothetical protein, Tb10.389.0740). A. GENECONV output after analysis of an alignment of gene copies 1–3. Similarity was inferred from the non-random distribution of shared polymorphisms among any two sequences; the likelihood of each phylogenetic grouping is represented by coloured rectangles: copies 1 and 2 as closest relatives (green); 1 and 3 (red); 2 and 3 (blue). B. Diagram of the chromosomal position of Tb109c. DNA strands are shown in grey, scale is in base-pairs. The tandem array is coloured red, other annotated genes are green and hypothetical genes are coloured blue. The identity of UTRs around each gene duplicate is denoted by geometric symbols; identical UTRs possess the same symbol. C. Phylogenetic tree for Tb109c homologs from four species; orthology is retained by the divergent fourth duplicate, producing a distinct clade (shaded). Values are bootstrap proportions out of 500.Back to article page
