This invention relates to isolated polynucleotides encoding chlorophyllases. The invention also relates to the construction of recombinant DNA fragments comprising all or a portion of the isolated chlorophyllase-encoding polynucleotides, in sense or antisense orientation, wherein expression of the recombinant DNA fragment results in production of altered levels of chlorophyllase in a transformed host cell.

Chlorophyllases

This invention relates to isolated nucleic acid fragments encoding lipoxygenases. The invention also relates to the construction of recombinant DNA constructs encoding all or a portion of the lipoxygenase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the lipoxygenase in a transformed host cell.

Plant lipoxygenases

This invention relates to a nucleic acid fragment encoding a plant 5-methyltetra-hydropteroyltriglutamate-homocysteine methyltransferase or methionine synthase. The invention also includes chimeric genes, a first encoding a plant methionine synthase (MS) gene, a second encoding a plant cystathionine &#x3b3;-synthase (CS) gene, a third encoding feedback-insensitive aspartokinase (AK) or bifunctional feedback-insensitive aspartokinase-homoserine dehydrogenase (AK-HDH), which is operably linked to a plant chloroplast transit sequence, and a fourth encoding a methionine-rich protein, all operably linked to plant seed-specific regulatory sequences. Methods for their use to produce increased levels of methionine in the seeds of transformed plants are provided.

This invention relates to an isolated nucleic acid fragment encoding a plant enzyme that catalyze steps in the biosynthesis of lysine, threonine, methionine, cysteine and isoleucine from aspartate, the enzyme a member selected from the group consisting of: dihydrodipicolinate reductase, diaminopimelate epimerase, threonine synthase, threonine deaminase and S-adenosylmethionine synthetase. The invention also relates to the construction of a chimeric gene encoding all or a portion of the enzyme, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the enzyme in a transformed host cell.

Plant amino acid biosynthetic enzymes

This invention relates to an isolated nucleic acid fragment encoding a thioredoxin protein. The invention also relates to the construction of a chimeric gene encoding all or a portion of the thioredoxin protein, in sense or antisense orientation, wherein expression of the chemeric gene results in production of altered levels of the thioredoxin protein in a transformed host cell.

Thioredoxin H homologs

Isolated nucleic acid fragments encoding starch synthase isoform V. are presented. Recombinant DNA constructs encoding all or a portion of starch synthase isoform V, in sense or antisense orientation, can be made, wherein expression of the recombinant DNA construct results in production of altered levels of the starch synthase isoform V in a transformed host cell.

Starch synthase isoform V

The present invention relates to isolated nucleic acids encoding a polypeptide having phytochelatin synthase activity. The invention also relates to recombinant DNA constructs comprising said nucleic acids; host cells transformed with said recombinant DNA constructs, and a method for producing recombinant phytochelatin synthase in said transformed host cells.
