*4.7. Chromosomal Localization*

According to the chromosomal positions of genes, we drew a map of the distribution of *Dof* genes throughout the physic nut genome using MapInspect software (Available online: http://mapinspect. software.informer.com/) [51]. The *Dof* gene pairs resulting from segmental or tandem duplication were linked by lines and marked in blue rectangle, respectively.
