Genomic regions with strong selective signals in populations of S. japonica

A: Distribution of log₂(θ_π ratios) and F_ST values calculated in 40 kb sliding windows with 20 kb increments between RS/ZS populations (ZS as control group). Data points in red (corresponding to top 5% of empirical log₂[θ_π ratio] distributions with values of >0.1204 and top 5% of F_ST distributions with values of >0.0904) are genomic regions under selection in RS population. B: Overlapping candidate genes in RS/ZS and RS/ST pairs based on Venn diagram. C: Overlapping candidate genes in ZS/RS and Japan/RS pairs based on Venn diagram. D: Allele frequency of one SNP within cold-temperature adaptation gene Picalm across five S. japonica populations, red and blue represent two types of bases at this locus. E: Allele frequencies of one SNP within warm-temperature adaptation gene SORCS3 across five S. japonica populations, red and blue represent two types of bases at this locus.
