Minor Alleles of the CaS Gene Are Enriched in Coastal Populations of A. thaliana.

(A) Geographic distribution of the top CaS SNP alleles in European accessions of the RegMap panel. CaS major alleles at the chromosome 5 position 7738620 (T) are depicted as blue symbols, whereas minor (A) alleles are depicted as red symbols.

(B) Box plot of the distances from collection sites of accessions containing minor (red) or major (blue) alleles to the nearest coast. x axis, genotype; y axis, approximate distance to nearest coast (km); whiskers, ± 1.5 times the interquartile range.
