The present invention is directed to compositions and methods for altering the levels of seed proteins in cereal grain. The invention is directed to the alteration of seed protein levels in plant grain, resulting in grain with increased digestibility/nutrient availability, improved amino acid composition/nutritional value, increased response to feed processing, improved silage quality, and increased efficiency of wet milling.

Grain quality through altered expression of seed proteins

Methods and compositions for modulating development and defense responses are provided. Nucleotide sequences encoding, soybean, wheat and rice cystatin proteins are provided. The sequences can be used in expression cassettes for modulating development, developmental pathways, and defense responses. Transformed plants, plant cells, tissues, and seed are also provided.

Crop plant cystatin proteinase inhibitors encoding nucleic acids and methods of use

The present invention is directed to a composition for altering the levels of seed proteins in cereal grain. The invention is directed to the alteration of seed protein levels in plant grain, resulting in grain with increased digestibility/nutrient availability, improved amino acid composition/nutritional value, increased response to feed processing, improved silage quality, and increased efficiency of wet or dry-milling. The composition provided comprises a nucleotide sequence encoding a maize 18 kD alpha-globulin cDNA as well as expression cassettes comprising nucleotide sequences of the invention. Also provided are transformed plant tissue including plants, cells and seeds thereof.

Plants transformed with a DNA construct comprising a nucleic acid molecule encoding an 18 kD &#x3b1;-globulin

The invention alters the physical characteristics of storage polyglucans including starch. Methods are provided to modify the polyglucan biosynthesis pathway by simultaneously altering the activity of a pullulanase debranching enzyme and the activity of another polypeptide in the polyglucan biosynthesis pathway. Compositions of the invention include transgenic plants and seeds having a modified polyglucan structure and/or content and elevated phytoglycogen levels. Additional compositions include a grain with increased energy availability for improved feed quality and industrial uses. Further compositions include a polyglucan with improved functional properties useful in a wide range of food and industrial applications.

Production of modified polysaccharides

The invention provides methods and compositions relating to altering carbohydrate metabolism and/or composition of plants. The invention provides isolated nucleic acids and their encoded proteins, expression cassettes, host cells, transgenic plants, and antibody compositions.
