Fig. 4

The chromosomal or scaffold distributions of the GmGRAS genes in the soybean genome. The red lines connected the tandem duplicated GmGRAS gene pairs. The chromosome or scaffold names were set at the left of the chromosomes or scaffold. The gene density of each chromosome or scaffold was evaluated by setting the genetic interval as 300-kb and was depicted by gradient colors from blue (low gene density) to red (high gene density). The blank regions on chromosomes or scaffold indicated that the genetic regions lacked gene distribution information
