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.
