Fig 7. Locations and lengths of the exons and introns of peach bHLH superfamily genes.

Exons and introns are presented as filled yellow sticks and thin gray single lines, respectively. UTRs are represented by dark blue bars at the ends. The red dotted line separates each subfamily and clearly presents the member conservation of each subfamily. The phylogenetic tree on the right was constructed using only the sequences of bHLH proteins in peach.
