Abstract: A method and composition for improving one or more indicators of bowel health or metabolic health in a mammalian animal. This comprises the delivering to the gastrointestinal tract of the animal an effective amount of an altered wheat starch in the form of or derived from the grain of a wheat plant. The proportion of amylose in the starch of the grain is at least 30% and/or the grain comprises a reduced level of SBEIIa enzyme activity and/or protein relative to wild-type grain.

Abstract: This invention relates to a new starch branching enzyme, and to the gene encoding the enzyme. In particular, the invention provides a new starch branching enzyme type II from wheat, the nucleic acid encoding the enzyme, and constructs comprising the nucleic acid. The invention also relates to a novel method for identification of branching enzyme type II proteins, which is useful for screening wheat germplasm for null or altered alleles of wheat branching enzyme IIb. The novel gene, protein and methods of the invention are useful in production of plants which produce grain with novel properties for food and industrial applications, for example wheat grain containing high amylose or low amylopectin starch.

Abstract: The present invention provides methods for distinguishing between different isoamylase genes of individual genomes of a polyploid plant. These methods enable a polyploid plant-to be produced and/or identified which has at least one impaired isoamylase gene. In particular, the methods of the invention enable various plants of a polyploidy species to be produced and/or indentified which, between the plants, lack a functional isoamylase gene for each genome of the plant. Such plants can be cross-bred to produce a plant which lacks any functional isoamylase protein. Furthermore, the invention provides numerous isoamylase gene, protein and cDNA sequences from various polyploidy plant species, including hexaploid wheat.
