The present invention relates to rice oil, rice bran and rice seeds which have altered levels of oleic acid, palmitic acid and/or linoleic acid. The present invention also provides methods for genetically modifying rice plants such that rice oil, rice bran and rice seeds produced therefrom have altered levels of oleic acid, palmitic acid and/or linoleic acid. Specifically this is achieved through modulation of Fad2 and/or FatB expression.

Rice plants and methods of producing rice grain

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.

Method of preparing food using rice oil

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.

Wheat with altered branching enzyme activity and starch containing products derived therefrom

Altering the fatty acid composition of rice

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.

Method and means for improving bowel health

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.

Rice and products thereof having starch with an increased proportion of amylose

Wheat with altered branching enzyme activity and starch and starch containing products derived therefrom

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%.

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.

Barley with altered branching enzyme activity and starch and starch containing products with an increased amylose content

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. 

The present invention provides isolated nucleic acid molecules encoding wheat starch synthases, and probes and primers derived therefrom, which are useful in the modification of plant starch content and/or composition, and for screening plant lines to determine the presence of natural and/or induced mutations in starch synthase genes which affect starch content and/or composition. More particularly, the isolated nucleic acid molecules of the present invention further provide for the screening-assisted breeding of plants having desirable starch content and/or composition, in addition to providing for the direct genetic manipulation of plant starch content and/or composition.

Genes encoding wheat starch synthases and uses thereof

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.
