Species-specific frequency of LCRs for multiple complexity thresholds in Apicomplexa. a Maximum likelihood phylogenetic tree of Apicomplexa species used for the phylogenetic contrast analysis. Pyo was excluded from this analysis because it lacked chromosome assignments for its proteins, which was necessary for the phylogenetic contrast analysis. The phylogeny was obtained using 30 orthologous genes randomly selected from Kuo et al. (2008). Bootstrap values are shown at each node. Species belonging to the same taxonomic group are shown (Hsp: Haemosporidia, Ppl: Piroplasmida, Ccd: Coccidia). b LCRs profiles with complexity thresholds = 0–3 (color coding refers to individual species and taxonomic groups: blue/purple: HSP; green: Ppl; Orange/brown: Ccd). c Linear regression on the logits of LCR frequencies. Values at K = 3 were excluded because virtually indistinguishable from the background composition
