Figure 5

(a) Putative sweep regions (yellow) around PHYC and FRS10 were obtained by accumulating and filtering composite likelihood ratio (CLR) statistics (red). Gene models are shown for each gene (purple), with the corresponding mRNA region highlighted in gray (or blue for genes under selection). (b) PCA plot based on SNPs 2 kb upstream and downstream of the sweep related to PHYC. (Sampling locations are color-coded as in Fig. 2). (c) RDA plot of the PHYC SNP region. Axis RDA1 is the direction that best correlates with principal components of maximum temperature (Tmax). In this case, Tmax explains 26.3% of the variation in the SNP data; the remaining variation is explained by PCA, where PC1 explains 50.5% (y axis). Inset, differences in yearly Tmax between Yakutsk and Krasnoyarsk, the locations most separated along RDA1.
