Overview of all MADS Box Complexes Involved in Floral Transition in Arabidopsis.

(A) Post-PIN network. Green lines denote all interactions that originated through γ, and red lines denote interactions that existed before the γ triplication. Proteins are ordered into their subfamilies by yellow boxes.

(B) and (C) MADS domain complexes before (B) and during early floral transition (C).

(D) MADS domain complexes at the start of floral organ development (stages 1 and 2) (D), during stage 3 (E), and in the mature flower (F). Red complexes existed before the γ triplication, green complexes evolved through the γ triplication, and light-blue complexes arose later. Dark-blue ellipses are proteins not in complex or not discussed here. Black circles are non-MADS domain proteins. Transparent proteins are weaker expressed in that stage. Dotted arrows denote suggested complex formation and functions.
