The invention relates to the genetic manipulation of plants, particularly to the expression of genes involved in oxylipin metabolism in plants. Nucleotide sequences encoding homologues of Old Yellow Enzyme, and inducible promoters and proteins thereof, are provided. The sequences find use in modifying oxylipin metabolism in plants, increasing the resistance of plants to stress, regulating gene expression in plants, and in the production of oxylipins in plants.
摘要:
The present invention provides polynucleotides and related polypeptides of the enzyme APAO isolated from Exophiala spinifera. Additionally, the polynucleotide encoding for the APAO enzyme can be used to transform plant cells normally susceptible to Fusarium or other toxin-producing fungus infection. Plants can be regenerated from the transformed plant cells. Additionally, the present invention provides for expressing both APAO and a fumonisin esterase in a transgenic plant. In this way, a transgenic plant can be produced with the capability of degrading fumonisin, as well as with the capability of producing the degrading enzymes. In addition, the present invention provides methods for producing the APAO enzyme in both prokaryotic and non-plant eukaryotic systems. Methods for detoxification in grain, grain processing, silage, food crops and in animal feed and rumen microbes are also disclosed.

The present invention provides polynucleotides and related polypeptides of the enzyme APAO isolated from Exophiala spinifera and Rhinocladiella airovirens. The polynucleotides may be mutated to remove glycosylation sites and cysteine residues. Additionally, the present invention provides recombinant expression cassettes, host cells, transgenic plants, and transgenic seed. The present invention also provides for polynucleotides containing both APAO and a fumonisin esterase. In addition, the present invention provides methods for producing the APAO enzyme in both prokaryotic and eukaryotic systems, methods for detecting fumonisins, and methods for identifying transformed plant cells. Methods for degrading fungal toxins in plants, grain, grain processing, silage, food crops and in animal feed are also disclosed.
摘要:
The invention relates to the genetic manipulation of plants, particularly to the expression of nucleotide sequences from defense-related signaling genes. Isolated nucleotide sequences encoding a neoxanthin cleavage enzyme, an amino acid permease, and a novel protein are provided. Also provided are isolated nucleotide sequences comprising promoters that drive expression in a plant in an inducible or tissue-preferred manner. The nucleotide sequences find use in increasing the resistance of plants to pathogens and other stresses, modifying ABA metabolism in plants, modifying amino acid transport and content in plants, and regulating gene expression in plants. Additionally provided are isolated proteins, and transformed plants and seeds thereof.
