摘要:
Barley having a reduced level of SBEIIa activity produces grain having a high relative amylose content. The barley might additionally have reduced levels of SBEIIb activity. The barley grain of this invention can be of a non-shrunken phenotype despite a lesion in the amylopectin synthesis pathway.
摘要:
Rice having reduced levels of starch branching enzymes produce grain having a high relative amylose content in the endosperm. The rice grain of this invention can be of a non-shrunken phenotype despite a lesion in the amylopectin synthesis pathway and may be transgenic or nontransgenic.

摘要:
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%.
摘要:
Wheat having a reduced level of SBEIIa activity, that may have a relative. high amylose content. Wheat having a mutant SBEIIa gene in the A genome. The wheat might additionally have reduced levels of SBEIIb activity. The wheat grain of this invention can be of a non-shrunken phenotype despite a lesion in the amylopectin synthesis pathway, and may also have a high relative amylose content.

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.
摘要:
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.
摘要:
The present invention relates to methods of preparing food using rice oil which has increased levels of oleic acid and decreased palmitic and linoleic acids, for increased stability to oxidation and health benefits.
