Derivatives of &#x3b1;-hordothionin made by position-specific substitution with lysine residues provide lysine enrichment while retaining the antifungal activity of the parent compound.

High lysine derivatives of &#x3b1;-hordothionin

This invention relates to newly identified polynucleotides and polypeptides in the phytic acid biosynthetic pathway, variants and derivatives of same; methods for making the polynucleotides, polypeptides, variants, derivatives and antagonists. In particular the invention relates to polynucleotides and polypeptides of the inositol polyphosphate kinase gene family. In particular this invention relates to using the newly identified polynucleotides and polypeptides to modulate the phytic acid biosynthesis in such a way as to decrease phytate and/or increase non-phytate phosphorous, especially in corn or soy animal feedstuffs.

Inositol polyphosphate kinase genes and uses thereof

The present invention provides a plant seed the endosperm of which is characterized as having an elevated level of a preselected amino acid. The present invention also provides expression cassettes, vectors, plants, plant cells and a method for enhancing the nutritional value of seeds.

Alteration of amino acid compositions in seeds

The present invention provides a method of reducing cholesterol in animals and food products derived from such animals. The method includes feeding to the animals a low phytate food source so that the phytate phosphorus intake of the animal is reduced.

A controllably constitutively female sterile plant is provided. A gene critical to female fertility is identified and the native gene inactivated. The gene is cloned, linked to an inducible promoter and inserted into the plant. The result is a plant that is constitutively female sterile with inducible female fertility.

Methods of mediating female fertility in plants

This invention relates to newly identified polynucleotides and polypeptides, variants and derivatives of same; methods for making the polynucleotides, polypeptides, variants, derivatives and antagonists. In particular the invention relates to polynucleotides and polypeptides of the phytate metabolic pathway.

Genes controlling phytate metabolism in plants and uses thereof

Fertility in a plant is controlled by inactivating a gene critical to fertility, and inserting into the plant the criticial gene linked to an inducible promoter.

Nucleotide sequences mediating fertility and method of using same

Compositions providing increased energy content of animal feed using plant crop biomass which include a polyhydroxyalkanoate have been developed. In one embodiment, the compositions can be prepared using conventional techniques for harvesting and processing plant crops into forms useful as animal feed, wherein the plant, or parts thereof, have accumulated PHA, preferably in excess of 2% by dry weight of the plant tissue. In a preferred embodiment, the PHA is accumulated in corn or an oilseed. The feed compositions can include the PHA-containing meal byproduct from corn or oilseed processing. In another embodiment, the PHA can be provided with the green tissue of plants, such as clover, alfalfa, sorghum, and silage corn.

Animal nutrition compositions

The present invention provides a method for increasing the levels of essential amino acids in seeds of plants, thereby enhancing the nutritional value of the seeds. The method comprises manipulating the metabolic pathway of the amino acid to provide an increased source of the target free amino acid and, concomitantly, over-expressing a preselected gene coding for the protein containing the target amino acid, such that there is accumulation of protein-bound target amino acid. A complementary protein sink is thus produced. The present invention is particularly useful in increasing levels of methionine, lysine and threonine in seeds.

Derivatives of .alpha.-hordothionin made by position-specific substitution with lysine residues provide lysine enrichment while retaining the antifungal activity of the parent compound.

High lysine derivatives of .alpha.-hordothionin

The present invention provides a plant seed obtained by crossing a first plant having reduced protease inhibitor activity with a second plant that is transformed to preferentially express a preselected protein whereby the content of an endogenous protein is diminished in the seed. Also provided are a method of reducing the level of endogenous proteins and a method of producing feed.

Methods of producing feed by reducing endogenous protein levels in

Fertility in a plant is controlled by inactivating a gene critical to fertility, and inserting into the plant the critical gene linked to an inducible promoter.

Nucleotide sequences mediating ferility and method of using same

A plant seed and method of producing the same, genetically modified to express a preselected protein, the expression of which reduces the level of an endogenous protein in the seed. In particular, expression of a sulfur-rich, seed storage protein reduces the level of protease inhibitors in seeds.
