Fig 8. Illustrtion of how the O2/ZmMADS47 complex may regulate zein gene expression.

The upper illustration shows ZmMADS47 alone (square) binds the CATGT motif but does not induce transactivation. The middle illustration shows O2 binding is able to transactivate its targets. The bottom illustration shows ZmMADS47 (oval) and O2 bind their respective motifs and the O2/ZmMADS47 complex enhances transactivation of gene targets.
