Abstract: Methods of genetically manipulating biologically active 4?-O-methylated isoflavonoids have been found based upon the regiospecifity of isoflavone 7-OMT in vivo. Upon transformation and expression of an isoflavonoid O-methyltransferase gene, up-regulation of IOMT in the transgenic plants can be used to increase the accumulation of 4?-O-methylated isoflavonoid phytolalexins, providing for increased disease resistance to the plant. Similar methods can be used to increase accumulation of 4?-O-methylated isoflavonoid nutraceuticals in plants. For down-regulation of IOMT in plants that naturally make 4?-O-isoflavonoid phytoalexins and 4?-O-methylated isoflavonoid nutraceuticals, IOMT gene sequences can be transformed in the antisense orientation.

Abstract: A modified ubiquitin regulatory system which lacks heatshock elements and so is not heat inducible can be used to regulate expression of a structural gene under the control thereof, e.g. by introducing an appropriate DNA construct into plant tissue.
Abstract: Protein Fragment Complementation Assays (PCA) are done in plant material using enzyme fragment constructs, for example, dihydrofolate reductase (DHFR) fragment constructs. Plant material is transformed with at least two different constructs that form different products capable of interacting to reconstitute enzymatic activity in the plant material. Detection of the activity can be done using a substrate for the enzyme in the culture medium which, when reacted with the enzyme, is converted to a detectable product. One embodiment uses a substrate that can be enzymatically converted to a detectable fluorescent product. An inducer such as rapamycin or salicylic acid can be added to the culture medium to increase the level of detectable product.

Abstract: 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.

Abstract: Disclosed are transgenic plants having edible portions that produce methional during processing. The plants contain increased methionine levels such that upon processing of the edible portion(s), methional levels are increased and lead to food products that possess improved flavor stability and/or quality. Plants of the Solanaceous family e.g., potato, tomato and eggplant, and other methional-producing plants including maize and soybean, are preferred plants. Several ways of genetically engineering plants to produce increased free Met levels are disclosed, with introduction of a non-native nucleic acid encoding cystathionine gamma synthase (CGS) and tissue-specific expression of an anti-sense S-adenosyl-methionine synthetase being preferred. Also disclosed are methods for selecting transformed plant cells using ethionine and CGS as the selection agent and marker gene respectively.
