    摘要： Wheat grain (Triticum aestivum) comprising an embryo and starch, wherein the embryo comprises two identical alleles of an SBEIIa-A gene, two identical alleles of an SBEIIa-B gene and two identical alleles of an SBEIIa-D gene, wherein each of the SBEIIa genes gives rise to an amount of protein (w/w) or a protein having SBEIIa activity which is lower than the corresponding wild-type gene, and at least one of said genes comprises a point mutation, wherein the starch comprises amylose such that the grain has an amylose content of at least 50% (w/w) as a proportion of the extractable starch of the grain.
