Extreme genome diversity in the hyper-prevalent parasitic eukaryote Blastocystis
Cumulative ortholog frequency is plotted on the y-axis while the x-axis represents the amino acid identity between orthologs. The more similar species pairs are to each other, the steeper the curve and further to the right. Note that the order of the pairs in the legend matches the order in the figure. Comparisons for Blastocystis STs were based on aligned regions of reciprocal best Basic Local Alignment Search Tool (BLAST) hits, while non-Blastocystis data were obtained from the authors of a comparative study of Giardia intestinalis . Data for this figure can be found in S12 Data.
