Abstract
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.
Claims15
A plant seed that is genetically modified to preferentially express a preselected protein, whereby the content of an endogenous protein is diminished in the seed,
- wherein the preselected protein is a protein which accumulates in the seed,
- wherein the preselected protein requires a limiting amino acid necessary to produce the primary construct of the endogenous protein,
- wherein the endogenous protein is an antinutritional protein, and
- wherein the plant seed is soybean, canola, corn, sunflower, wheat, barley, oats, millet, rice, sorghum or rye.
A method of reducing the level of an endogenous protein in a plant seed comprising transforming a plant to express a preselected protein in the seed at a level sufficient to inhibit the synthesis of the endogenous protein,
- wherein the preselected protein is a protein which accumulates in the seed,
- wherein the preselected protein requires a limiting amino acid necessary to produce the primary construct of the endogenous protein,
- wherein the endogenous protein is an antinutritional protein, and
- wherein the plant seed is soybean, canola, corn, sunflower, wheat, barley, oats, millet, rice, sorghum or rye.
