Chromosomal localization and duplication of HDAC genes in soybean. Each box refers to a chromosome, and chromosome numbers are shown beside each chromosome. The scale is in megabase. The approximate location of each soybean HDAC gene is indicated by a short orange line. Colored lines in the circle indicate the linkage group with segmentally duplicated HDAC gene pairs, and segmental duplication regions were determined using the Plant Genome Duplication Database
