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

Abstract: 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 ?-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.

Abstract: This invention relates to an isolated nucleic acid fragment encoding a UDP-galactose 4-epimerase. The invention also relates to the construction of a chimeric gene encoding all or a portion of the UDP-galactose 4-epimerase, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the UDP-galactose 4-epimerase in a transformed host cell.

Abstract: The invention provides isolated peptide-methionine sulfoxide reductase nucleic acids and their encoded proteins. The present invention provides methods and compositions relating to altering peptide-methionine sulfoxide reductase levels in plants. The invention further provides recombinant expression cassettes, host cells, transgenic plants, and antibody compositions.
