  • CORN PLANTS AND SEED ENHANCED FOR ASPARAGINE AND PROTEIN
    Publication number: 20110293815
    Abstract: The present invention relates to a corn plant and seed with enhanced levels of protein and amino acids. The invention also relates to DNA constructs that provide expression in transgenic corn cells of an asparagine synthetase enzyme. The DNA constructs are used in a method to produce transgenic corn plants and seeds and to select for plants and seeds with enhanced levels of protein and amino acids.
    Type: Application

  • Transgenic plants with enhanced agronomic traits
    Publication number: 20090165165
    Abstract: This invention provides transgenic plant cells with recombinant DNA for expression of proteins that are useful for imparting enhanced agronomic trait(s) to transgenic crop plants. This invention also provides transgenic plants and progeny seed comprising the transgenic plant cells where the plants are selected for having an enhanced trait selected from the group of traits consisting of enhanced water use efficiency, enhanced cold tolerance, increased yield, enhanced nitrogen use efficiency, enhanced seed protein and enhanced seed oil. Also disclosed are methods for manufacturing transgenic seed and plants with enhanced traits.
