Abstract excerpt

The amylose extender (ae(-)) mutant of maize lacks starch branching enzyme IIb (SBEIIb) activity, resulting in amylopectin with reduced branch point frequency, and longer glucan chains. Recent studies indicate isozymes of soluble starch synthases form high molecular weight complexes with SBEII isoforms. This study investigated the effect of the loss of SBEIIb activity on interactions between starch biosynthetic...
