Abstract excerpt

KEY MESSAGE: Mutation of the BEIIb gene in an isa1 mutant background mitigates the negative effect of the ISA1 mutation on grain filling, and facilitates recovery of amyloplast formation in rice endosperm. In this study, the effect of branching enzyme IIb and isoamylase 1 deficiency on starch properties was demonstrated using high resistant starch rice lines, Chikushi-kona 85 and EM129. Both lines harbored a...
