Figure 4. Differentiation of slc26a10 in pairwise comparisons between anadromous Dolly Varden charr and the Lake Kronotskoe species flock.

Figure 4.

(A) The slc26a10 locus shows high differentiation (Fst). The gene locus contains one highly differentiating non-coding and one coding variant. Dolly Varden slc26a10 is homologous to human pendrin (SLC26A4), a known thyroid regulator. The broader locus has low nucleotide diversity as illustrated by sliding window plots of Tajima’s Pi. Horizontal dotted gray line represents Fst = 0.9. Plots are included for 10kb sliding windows along LG17, the coding elements within the broader locus, the number of variants per sliding window, Fst, and Tajima’s Pi per sliding window in pairwise comparisons between riverine Dolly Varden charr and the Lake Kronotskoe species flock. (B) Slc26a10 contains a fixed amino acid substitution in a conserved proline that differentiates Dolly Varden charr from each of the major clades of the lacustrine morphs.
