  • Biological nitrogen fixation in crops
    Patent number: 11434498
    Abstract: A method of transforming a mitochondrion of a plant cell to express a nitrogenase enzyme includes exposing the plant cell to a mitochondrial-targeting nanocarrier polypeptide and one or more nucleic acids encoding the nitrogenase enzyme. The one or more genes encoding the nitrogenase enzyme can be one or more Klebsiella nif genes. The method can be used to generate plants which have the capability of fixing atmospheric elemental nitrogen.
    Type: Grant

  • T-DNA/PROTEIN NANO-COMPLEXES FOR PLANT TRANSFORMATION
    Publication number: 20120070900
    Abstract: A DNA/protein nano-complex for transfecting eukaryotic cells, wherein the nano-complex comprises an expressible nucleotide molecule complexed with a VirD2 protein molecule, and a RecA protein molecule complexed with the nucleotide molecule/VirD2 protein molecule complex. The nucleotide molecule/VirD2 protein molecule/RecA protein molecule complexed may be further complexed to a cell penetrating peptide. The DNA/protein nano-complex can be used for delivering the expressible nucleotide molecule to target plant cells, in particular, monocot plant cells exemplified by wheat cells, corn cells, triticale cells, barley cells, and rye cells.
