  • Synthetic insecticidal gene, plants of the genus oryza transformed with the gene, and production thereof
    Patent number: 5436391
    Abstract: A synthetic gene encoding an insecticidal protein, the gene is provided having a base sequence which has been modified to bring the codon usage in conformity with the genes of gramineous plants particularly rice plants. A preferred gene sequence is shown in SEQ ID NO: 1. An expression vector containing said structural gene is provided. A method for producing recombinant gramineous plants is provided, which comprises transforming protoplasts derived from gramineous plants with the vector, incubating the protoplasts in a liquid medium in the presence of cultured cells of the plants to form colonies and regenerating plants from said colonies. Recombinant gramineous plants having resistance against insects are also provided.
