Figure 4.

Scenarios of terminus diversity in duplicated gene pairs of the SET gene family in Populus. This figure shows potential mechanisms and their possible consequences leading to the four scenarios of terminus diversity observed in duplicated gene pairs. Exons, green filled boxes; introns, black single lines. Untranslated regions (UTRs) are indicated by thick blue lines.
