Genomic distributions of GmCYP genes on soybean chromosomes . Chromosomal locations of GmCYPs are indicated based on the location of the genes, length of chromosomes and positions of centromeres. The chromosomes are drawn to scale and chromosome numbers are shown under each chromosome. The GmCYPs that are clustered together and speculated to have undergone segmental duplication are indicated by shaded boxes of the same color and connected to each other by a line. Centromeres are indicated by blue ovals.
