Abstract:
1. Grain obtained from a rice plant, comprising (i) starch, (ii) an exogenous nucleic acid molecule comprising a sequence which is the same as, or fully complementary to, a nucleotide sequence of at least 50 contiguous nucleotides of the starch branching enzyme IIa (SBEIIa) gene coding region whose sequence is set forth in SEQ ID NO:2 which inhibits the expression of a rice SBEIIa gene, (iii) a reduced level of SBEIIa protein and, (iv) a reduced level of starch branching enzyme IIb (SBEIIb) protein in the rice grain, the reduced level of SBEIIa protein and of SBEIIb protein being relative to rice grain of an Indica variety, wherein the proportion of amylose in the starch of the grain is at least 40% as measured by an iodometric method.
