Chromosomal locations, region duplication, and predicted cluster for soybean MYB genes. Chromosomal positions of the MYB genes in soybean are mapped on the basis of JGI soybean Genome version 7.0. The chromosome number is indicated above each chromosome. The scale is in megabases (Mb). The number below the chromosome name indicates the length. The phylogenetic category of each gene (Figure 2) is indicated by the subgroup number. Each pair of duplicated MYB genes is connected with a red line. Connecting lines mark the specific cases in which there is a strong correlation between duplicated genomic regions and the presence of MYB genes with closely related predicted amino acid sequences. Colored boxes indicate groups of gene clusters with paralogous and syntenic genes on the chromosomes. Yellow bars on the chromosomes and blue numbers beside the bars indicate the 24 predicted duplication regions. The green and white bars on the chromosomes indicate the centromeres and pericentromeres, respectively.
