Environmental associations identified on chromosome 20 of the Glycine max genome. (a) Significant association signals were identified for geography, soil and precipitation variables between 45864382–47884469 bp on chromosome 20. (b) Linkage disequilibrium and haplotype analysis using the four gamete algorithm within the range of significant SNP between 45864382–47884469 bp. (c) Zoomed-in view of a narrowed region around the significant markers. The Arabidopsis ortholog for the nearest gene, Glyma.20G225400, is annotated as Dehydration-Responsive Element Binding Protein2a (DREB2A). (d) Density plot of allele frequency distribution for annual mean precipitation. (e) Geographic location of individuals with the C allele (gray) or T allele (gold) with jitter added to show overlapping samples. Maps were created with the RgoogleMaps 54.
