Locus map and duplication event coordinates of paralogous Gm Hsp 20 gene candidates. The identity of each linkage group is indicated at the top of each bar. Only the chromosomes where GmHsp 20 genes were mapped are shown. Possible duplicated genes are connected by lines, and the percentage of identity is annotated in the same stroke color. Gray rectangles indicate segmental duplications. The bar located on the left side indicates chromosome sizes in megabases.
