White-core endosperm floury endosperm-4 in rice is generated by knockout mutations in the C-type pyruvate orthophosphate dikinase gene (OsPPDKB).

Abstract excerpt

We have isolated a floury endosperm-4 (flo4) rice mutant with a floury-white endosperm but a normal outer portion. Scanning electron microscopic analysis revealed that this abnormal endosperm consisted of loosely packed starch granules. The mutant phenotype was generated by T-DNA insertion into the fifth intron of the OsPPDKB gene encoding pyruvate orthophosphate dikinase (PPDK). Plants containing flo4-1 produced...
