  • Patent number: 7038113
    Abstract: Soybean and Medicago truncatula CYP93C genes have been isolated which encode a cytochrome P450 that can catalyze the aryl migration of a flavanone to yield an isoflavanone intermediate or an isoflavone. Plants can now be genetically engineered to produce isoflavones that provide potential human health benefits and increase disease resistance in plants. Isoflavones can now be produced in transgenic plants species in which isoflavones do not naturally occur, i.e., in species other than legumes. Alternatively, introducing infection-inducible isoflavonoid biosynthesis into non-legumes qualitatively complements these plants phytoalexin defenses against microbial pathogens, whereas over-expression of the isoflavonoid pathway in legumes quantitatively increases this defense response. Finally, modifying the extend of production of isoflavonoids in legume roots positively impacts nodulation efficiency and therefore plant yield.

  • Patent number: 6936708
    Abstract: Alfin1 cDNA encodes a putative transcription factor associated with salt tolerance in alfalfa (Medicago sativa L). The recombinant protein binds DNA in a sequence specific manner, including promoter fragments of the salt inducible gene MsPRP2. Alfin1 function was tested in transgenic alfalfa under the control of the 35S promoter in the sense and antisense orientations with the endogenous MsPRP2 as a reporter gene. Calli overexpressing Alfin1 were more resistant to growth inhibition by 171 mM NaCl than vector transformed controls, while calli expressing Alfin1 antisense were more sensitive to salt inhibition. Transgenic plants overexpressing Alfin1 in the sense orientation grew well. In contrast, the antisense transgenic plants grew poorly in soil, demonstrating that Alfin1 expression is essential for normal plant development. Transgenic calli and plant roots overexpressing Alfin1 showed enhanced levels of endogenous MsPRP2 mRNA accumalution.

  • Patent number: 6936749
    Abstract: Nonsymbiotic hemoglobins are broadly present across evolution; however, the function of these proteins is unknown. Cultured maize cells have been transformed to constitutively express a barley hemoglobin gene in either the sense (HB+) or antisense (HB?) orientation. Hemoglobin protein in the transformed cell lines was correspondingly higher or lower than in wild type cells under normal atmospheric conditions. Limiting oxygen availability, by placing the cells in a nitrogen atmosphere for 12 hours, had little effect on the energy status of cells constitutively expressing hemoglobin, but had a pronounced effect on both wild type and HB? cells, where ATP levels declined by 27% and 61% respectively. Energy charge was relatively unaffected by the treatment in HB+ and wild type cells, but was reduced from 0.91 to 0.73 in HB? cells suggesting that the latter were incapable of maintaining their energy status under the low oxygen regime. Similar results were observed with P.

  • Patent number: 6916973
    Abstract: The present invention includes modified phytochrome A (PHYA) nucleic acid molecules in which DNA sequences coding for “active site” amino acid residues have been mutated to generate hyperactive phytochromes. In particular; a serine/threonine residue at the hinge between the N- and C-terminal domains as well as at the N-terminal serine/threonine cluster of phytochromes (e.g., serine-598 and serine-7 in oat phytochrome A) for (a) Pr/Pfr-dependent phosphorylation and (b) dephosphorylation by a phytochrome phosphatase (PP2A) was substituted with alanine. (c) In addition, amino acid residues within the phytochrome chromophore pocket are mutated to generate the bathchromic shift of the Pr-absorption band of both wild type and above-mentioned mutant phytochromes.

  • Patent number: 6911576
    Abstract: Nitrogen is one of the principal factors limiting vegetative production. The present invention has improved the nitrogen metabolism in Poplar by integrating a transgene constitutively expressing a pine glutamine synthetase into the plan genome. The resulting transgenic trees exhibit higher growth rates, protein and chlorophyll contents, and leaf area than equivalent untransformed trees. It is contemplated that this approach to nitrogen improvement will be equally successful for all woody perennials. Provided with the invention is an expression casette, a vector, and a method for increase glutamine synthetase activity in woody perennials, as well as transgenic woody perennials with enhanced nitrogen metabolism and accompanying phenotype.
