Contents and structures of branched and linear maltodextrins, malto-oligosaccharides, and sugars in the early developmental stage of phosphorylase1 mutant endosperm of rice.

Abstract excerpt

Biochemical analysis of plastidial phosphorylase (Pho1)-deficient mutants of rice strongly suggests that Pho1 plays an important role in the initiation of starch biosynthesis in the endosperm. The present study examined structures and amounts of maltodextrins, malto-oligosaccharides (MOS) as well as sugars in maturing rice endosperm and compared between a pho1-mutant line EM633 and its wild-type cultivar...
