"Long" SSRs are the 10,10.12 repeats. "Short" SSRs are the 8,8,9 repeats with the 10,10,12 repeats excluded. These are shown for the 24 taxa in Table 7. (middle) The relationship between total SSR number and genome size (in nucleotides) for the 24 taxa. (bottom) The relationship of A+T-richness (the overall A+T percentage of the genome) and the frequency of A and T mononucleotide repeats for the 10 taxa involved in the more detailed comparison. No other SSR category showed a relationship to any aspect of nucleotide composition

The height of the blue histogram topped by the horizontal black lines indicates the degree of similarity; similarity histograms are blue except where we have re-colored yellow the regions equivalent to (top) and (bottom) to highlight those regions. [The black horizontal lines without blue bars subtending them indicate short regions of similarity, basically SDRs. Red bars above the histogram indicate evolutionary conserved regions as determined in Mulan.] In interpreting the diagram, essentially the more blue (or yellow) in a region, the more similar are the two sequences. (Top) Comparisons, relevant to the conservation of , of six IGS regions from were made to (A), (B), (C), (D), (E), (F), (G), (H), (I), (J), (K), (L), (M), and (N). (Bottom) Comparisons, relevant to the conservation of , of introns from were made to those of (A), (B), (C), (D), (E), (F), (G), (H), (I), (J), (K), (L), (M), and (N)
