  • Methods for the identification of genes involved in abiotic stress tolerance in plants
    Patent number: 9546377
    Abstract: Methods are described for the identification of genes useful for conferring tolerance in plants to abiotic stress. Transgenic plants and seeds comprising the stress tolerant genes are also described. Methods to monitor the growth rate of the transgenic plants under stressed or non-stressed conditions are also described.

  • DROUGHT TOLERANT PLANTS AND RELATED CONSTRUCTS AND METHODS INVOLVING GENES ENCODING DTP4 POLYPEPTIDES
    Publication number: 20160369295
    Abstract: Isolated polynucleotides and polypeptides and recombinant DNA constructs useful for conferring stress tolerance are presented herein, along with compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs. The recombinant DNA construct comprises a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotide encodes a DTP4 polypeptide.

  • AGRONOMIC CHARACTERISTICS UNDER NITROGEN LIMITING CONDITIONS FOR PLANTS EXPRESSING PH11 OR NUCPU29 POLYPEPTIDES
    Publication number: 20160040181
    Abstract: Isolated polynucleotides and polypeptides and recombinant DNA constructs particularly useful for altering agronomic characteristics of plants under nitrogen limiting conditions are described. Compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs also are described. The recombinant DNA construct may comprise a polynucleotide operably linked to a heterologous promoter functional in a plant, wherein said polynucleotide encodes a PH11 or a NUCPU29 polypeptide.
