Generation of plants with altered protein, fiber, or oil content

1. A transgenic plant, comprising a plant transformation vector comprising a nucleotide sequence that encodes an IMQ polypeptide at least 95% identical to the amino acid sequence as set forth in SEQ ID NO: 96, whereby the transgenic plant has an improved meal quality phenotype, relative to control plants.

2. The transgenic plant of claim 1 , wherein the IMQ polypeptide comprises the amino acid sequence as set forth in SEQ ID NO: 96.

3. The transgenic plant of claim 1 , which is selected from the group consisting of plants of the Brassica species, including canola and rapeseed, soy, corn, sunflower, cotton, cocoa, safflower, oil palm, coconut palm, flax, castor, peanut, wheat, oat, and rice.

4. The transgenic plant of claim 3 , wherein the plant is canola.

5. The transgenic plant of claim 1 , wherein an improved meal quality phenotype comprises an increase in available metabolizable energy in meal produced from seeds of the transgenic plant, relative to control plants.

6. The transgenic plant of claim 5 , wherein an increase in available metabolizable energy comprises an altered protein content in the seeds of the transgenic plant.

7. The transgenic plant of claim 5 , wherein the protein content is increased.

8. A plant part obtained from the plant according to claim 1 .

9. The plant part of claim 8 , which is a seed.

10. Meal, feed, or food produced from the seed of claim 9 .

11. A method of producing meal, comprising growing the transgenic plant of claim 1 , and recovering meal from the plant, thereby producing meal.

12. The method of claim 11 , wherein the meal is produced from seeds of the plant.

13. A method of producing an improved meal quality phenotype in a plant, said method comprising:

a) introducing into progenitor cells of the plant a plant transformation vector comprising a nucleotide sequence that encodes an IMQ polypeptide comprising the amino acid sequence as set forth in SEQ ID NO: 96,

b) growing the transformed progenitor cells to produce transgenic plants, wherein the nucleotide sequence is expressed,

c) screening the resultant transgenic plants for an improved meal quality phenotype, wherein at least one of the transgenic plants exhibit an improved meal quality phenotype relative to control plants, and

d) selecting at least one of the transgenic plants that exhibit an improved meal quality phenotype;

thereby producing the improved meal quality phenotype in the plant.

14. The method of claim 13 , wherein the IMQ polypeptide comprises the amino acid sequence as set forth in SEQ ID NO: 96.

15. A plant obtained by a method of claim 13 .

16. The plant of claim 15 , which is selected from the group consisting of plants of the Brassica species, including canola and rapeseed, soy, corn, sunflower, cotton, cocoa, safflower, oil palm, coconut palm, flax, castor, peanut, wheat, oat, and rice.

17. The plant of claim 16 , wherein the plant is canola.

18. The plant of claim 15 , wherein the plant is selected from the group consisting of a plant grown from said progenitor cells, a plant that is the direct progeny of a plant grown from said progenitor cells, and a plant that is the indirect progeny of a plant grown from said progenitor cells.

19. A feed, meal, grain, food, or seed comprising a polypeptide encoded by a heterologous nucleic acid sequence at least 95% identical to the nucleic acid sequence as set forth in SEQ ID NO: 95.

20. The feed, meal, grain, food, or seed of claim 19 , wherein the polypeptide is encoded by the nucleic acid sequence as set forth in SEQ ID NO: 95.

21. A feed, meal, grain, food, or seed comprising a polypeptide comprising a heterologous amino acid sequence at least 95% identical to the amino acid sequence as set forth in SEQ ID NO: 96.

22. The feed, meal, grain, food, or seed of claim 21 , wherein the polypeptide comprises an amino acid sequence as set forth in SEQ ID NO: 96.
