Schematics of speculated starch biosynthetic protein complexes in wild-type (SS1/ss2a^L/SS3a), ss1^L/ss2a^L/SS3a, SS1/ss2a^L/ss3a and ss1^L/ss2a^L/ss3a. Selected combinations of predicted protein-protein complexes in developing seed of japonica rice (SS1/ss2a^L/SS3a) [23] are shown as wild-type (a). Alterations of protein complexes in ss1^L/ss2a^L/SS3a (b), SS1/ss2a^L/ss3a (c) and ss1^L/ss2a^L/ss3a (d) are illustrated. Boxes indicate an altered protein complex. SS isozymes that were missing or reduced compared with wild-type are indicated in gray. Newly recruited speculated SS isozymes are indicated with a bold oval. Black arrows indicate a reduced molecular weight due to missing enzymes. Gray arrows indicate recruitment of enzymes. Note that all lines used in this study have low SSIIa activity
