Schema chart of relationships between RegionA and 45S rDNA from divergence to domestication and improvement. Two possible scenarios for the RegionA origin were shown: a RegionA originated from the common ancestor of Tripsacum and Zea, and their sequence conservation resisted the reshuffling through the long term of evolution; b the introgression occurred during the process of Zea speciation, and at that moment Tripsacum could possibly be compatible to cross with. For Zea genus (blue chromosomes), RegionA fragments (red) were always protected by rDNA (green); for Tripsacum (yellow chromosomes) and common ancestor (gray chromosomes), RegionA fragment (red) and rDNA (green) were located in different chromosomes
