Figure 10.

Divergence of the various GLO duplicate pairs within the Solanaceae. The protein sequence identity was given between each paralogous pair. In the column of the protein dimerization and regulation, a black line indicates heterodimerization, and a dot near the proteins indicates homodimerization. The curved line with arrows in light green or dark green indicates activation or autoregulation, respectively. The blocked line in red indicates gene repression. The dashed arrow indicated a proposed role needing verification. A dashed box indicates that the two duplicates function as a unit. The functional evolutionary fate and the genetic interaction of each paralogous pair are given. A complete B function is defined as the mutation(s) that could lead to a complete homeotic transformation of the petal and stamen. A slash indicates “no” for this item. Calyx and corolla are homologous to sepals and petals, respectively. For details, please see text. Se, Sepal; Pe, petal; St, stamen; Ca, carpel.
