From: Unresolved orthology and peculiar coding sequence properties of lamprey genes: the KCNA gene family as test case

Figure 6

Comparison of codon usage for KCNA and other genes. (A) Plot of ENc against GC3 of sea lamprey genes. The curve indicates expected ENc-GC3 pattern under the assumption that there is no selection acting on codon usage. KCNA genes are shown as black dots and the remaining gene are represented by grey dots. (B) Factor map for synonymous codon usage of sea lamprey genes by crossing the first and second axes of WCA. KCNA genes are shown as black dots and the remaining gene are represented by grey dots. (C) Plot of the first factor of the WCA of codon usage in the sea lamprey against GC3 values of sea lamprey gene. KCNA genes are shown as black dots and the remaining gene are represented by grey dots. (D) Plot of genome-wide ENc against GC3 of 15 vertebrate species. (E) Factor map for synonymous codon usage of 15 vertebrate species at genome-wide level. (F) Plot of the first factor of the WCA of genome-wide synonymous codon usage against genome-wide GC3. Species names are abbreviated as in Figure 5.
