摘要:
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:
Compositions and methods to aid in protecting the plant from invading pathogenic organisms are provided. The compositions of the invention comprise genes that influence the levels of nitric oxide in plant cells. Such genes include those encoding nitric oxide synthase (iNOS) as well as natural resistance-associated macrophage proteins (NRAMP) and NRAMP homologues. A pathogen inducible promoter or alternatively a constitutive, preferably a weak constitutive, promoter is used to control the desired level of disease control in the plant. Transformed plants, plant cells, tissues, and seed are also provided having enhanced disease resistance.
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.

摘要:
The present invention provides methods and compositions relating to creating or enhancing disease resistance in plants. The invention provides isolated maize Rac nucleic acids and their encoded proteins that are involved in the altering the disease resistance pathway in plants, increasing transformation efficiency, inducing programmed cell death, and modulating the oxidative burst in a plant. The invention further provides recombinant expression cassettes, host cells, transgenic plants, and antibody compositions.
摘要:
CMIII, a small, basic maize seed peptide has been found to have antimicrobial properties. In a preferred embodiment, plant resistance to diseases caused by plant pathogens which are susceptible to CMIII is produced by inserting into the cells of a plant a gene whose expression causes production CMIII in antimicrobial amounts.
