Figure 4.

Heterodimers of type I MADS domain proteins in the embryo sac and developing seed. The different dimeric complexes that potentially can occur in the antipodal cells, central cell, embryo, and (chalazal) endosperm in planta are shown in color code in the schematic drawings of the embryo sac and developing seed. The legend on the right shows the different combinations of paralogous proteins that can probably act redundantly in the same complexes. The numbers indicate the different AGLs (e.g. 80 = AGL80; De Folter et al., 2005). Complexes that are probably more abundant are shown more often.
