A plant, the nuclear genome of which is transformed with a recombinant DNA sequence encoding a superoxide dismutase which renders the plant stress-resistant. The recombinant DNA sequence also optionally encodes a targeting peptide, fused to the superoxide dismutase, so that the superoxide dismutase is expressed in the cytoplasm of the plant's cells and is subsequently targeted to mitochondria or chloroplasts of the plant's cells or is secreted, via the endoplastic reticulum, from the plant's cells. |
