  • Nitrogen-Regulated Sugar Sensing Gene and Protein and Modulation Thereof
    Publication number: 20070250956
    Abstract: The present invention relates to a nitrogen-regulated GATA transcription factor gene required for sugar sensing and the modulation of the expression of this gene to modulate a characteristic in a plant. The GATA transcription factor of the present invention is involved in regulating sugar sensing in plants and its expression is influenced by nitrogen status. Increased expression of this or substantially similar genes can produce plants with improved nitrogen utilization and increased yield.

  • Method of producing transgenic maize using direct transformation of commercially important genotypes
    Publication number: 20060117407
    Abstract: Methods for transformation of maize with nucleic acid sequences of interest are disclosed. The method involves subjecting immature zygotic embryos or Type I callus to high velocity microprojectile bombardment. The method is capable of producing transformed maize lines of commercial importance and their hybrid combinations.

  • Synthetic DNA sequence having enhanced insecticidal activity in maize
    Publication number: 20060021095
    Abstract: DNA sequences optimized for expression in plants are disclosed. The DNA sequences preferably encode for an insecticidal polypeptides, particularly insecticidal proteins from Bacillus thuringiensis. Plant promoters, particular tissue-specific and tissue-preferred promoters are also provided. Additionally disclosed are transformation vectors comprising said DNA sequences. The transformation vectors demonstrate high levels of insecticidal activity when transformed into maize.

  • Self-aligning peptides modeled on human elastin and other fibrous proteins
    Patent number: 6765086
    Abstract: A polypeptide is provided that has a secondary structure characterized by at least three beta-sheet/beta-turn structures, and that is not a naturally occurring fibrous protein. Such polypeptides, illustrated by one modeled on elastin, are useful in prosthesis.

  • Herbicidal tolerant plants containing rat glutathione S-transferase gene
    Patent number: 5073677
    Abstract: The invention relates to plant cells and dicotyledonous plants transformed with chimeric rat glutathione-S-transferase gene constructs. Transgenic tobacco plants and progeny expressed the chimeric gene constructs under the control of a plant promoter. The transgenic plants and progeny demonstrated resistance to a herbicide which is normally inhibitory to plants not expressing the chimeric construct.
