Other claims from this paper (7)
- Intervention effect The ae mutation reduced short amylopectin chains of degree of polymerization 17 or less, especially 8 to 12, in rice endosperm.
- Association The extent of the amylopectin change correlated with starch-granule gelatinization properties measured by solubility in urea.
- Intervention effect SSI activity was significantly lower in the ae mutant than in wild type.
- Intervention effect Activities of BEI, BEIIa, ADP-Glc pyrophosphorylase, and isoamylase were unaffected by the ae mutation.
- Intervention effect Activities of pullulanase and Suc synthase were unaffected by the ae mutation.
- Mechanism The authors conclude that BEIIa and BEI cannot complement BEIIb function.
- Mechanism The authors infer that BEIIb specifically transfers short chains that SS may extend into A and B(1) amylopectin chains.
