    摘要： Compositions and methods for increasing the level of one or more selected free ε and/or α-N-acetylated amino acids in a selected tissue or organ of a plant are provided. In specific embodiments, the plant, plant part, seed or grain comprises a free α-N-acetylated amino acid content of at least 200 ppm or a ratio of free α-N-acetylated amino acid content to free non-α-N-acetylated amino acid content of about 3 to about 1000. Compositions comprising plants, plant parts, seed and grain having stably incorporated into their genome a heterologous polynucleotide encoding an amino acid-N-acetyltransferase polypeptide operably linked to a promoter active in the seed are provided. Further provided are compositions comprising a plant, plant part, seed or grain having stably incorporated into their genome a first heterologous polynucleotide encoding a first amino acid-N-acetyltransferase polypeptide operably linked to a first promoter active in the seed and a second heterologous polynucleotide encoding a second amino acid-N-acetyltransferase polypeptide operably linked to a second promoter active in the seed, wherein the first and the second amino acid-N-acetyltransferase polypeptide acetylate the α-amine of distinct amino acids. Compositions comprising food sources, feed and supplements, along with methods of increasing the nutritional value of a plant, plant part, seed or grain, are further provided.

    摘要： This invention relates to an isolated nucleic acid fragment encoding a serine palmitoyltransferase Lcb1 subunit. The invention also relates to the construction of a chimeric gene encoding all or a portion of the serine palmitoyltransferase Lcb1 subunit, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the serine palmitoyltransferase Lcb1 subunit in a transformed host cell.
