  • Plant drought tolerance and nitrogen use efficiency by reducing plant sensitivity to ethylene
    Publication number: 20150159166
    Abstract: The present disclosure provides polynucleotides and related polypeptides which are used to modify ethylene sensitivity in plants. Ethylene insensitive transgenic maize plants produce higher grain yields in water deficient and low nitrogen environments than non-transgenic plants. Through controlled expression of the transgene in desired tissues and organs, or specific plant developmental stages, the ethylene perception and signal transduction is altered to create transgenic plants which yield better under abiotic stress.

  • MAIZE MULTIDRUG RESISTANCE-ASSOCIATED PROTEIN POLYNUCLEOTIDES AND METHODS OF USE
    Publication number: 20120058244
    Abstract: Compositions and methods are provided for modulating the level of phytate in plants. More specifically, the invention relates to methods of modulating the level of phytate utilizing nucleic acids comprising multidrug resistance-associated protein (MRP) nucleotide sequences to modulate the expression of MRP(s) in a plant of interest. The compositions and methods of the invention find use in agriculture for improving the nutritional quality of food and feed by reducing the levels of phytate and/or increasing the levels of non-phytate phosphorus in food and feed. The invention also finds use in reducing the environmental impact of animal waste.
