Summary for Patent: 6,342,660
Title: | DNA construct containing Bacillus thuringiensis gene and plants containing it |
Abstract: | The present invention is drawn to a novel DNA construct comprising an expression cassette having a constitutive promoter which functions in plant cells operably linked to a maize alcohol dehydrogenase intron, a DNA sequence of a gene encoding a Cry 1Ab protein, and a terminator functional in plants and optionally further comprising a second cassette including a promoter which functions in plants operably linked to a maize alcohol dehydrogenase intron, a DNA sequence of a gene encoding for phosphinothricin acetyl transferase, and a terminator functional in plants wherein the two cassettes are transcribed in the same direction. Also provided are transgenic plants, particularly maize plants, having such a construct stably incorporated into their genomes. |

Application Number: | 09/330,714 |
Patent Claims: | 1. Seed of maize inbred line R583H having been deposited under ATCC Accession No: 209671.
2. Seed according to claim 1, wherein said seed comprises a nucleic acid construct comprising two cassettes, wherein the first cassette comprises a CaMV 35S constitutive promoter operably linked to a maize alcohol dehydrogenase intron, a DNA sequence of a gene encoding a Cry1Ab protein, and a terminator functional in plants, and the second cassette comprises a CaMV 35S promoter which functions in plant cells operably linked to a maize alcohol dehydrogenase intron, a DNA sequence of a gene encoding for phosphinothricin acetyl transferase, and a terminator functional in plants, wherein the two cassettes are transcribed in the same direction, wherein the nucleic acid construct is incorporated into the seed's genome on chromosome 8, near position 117, between markers Z1B3 and UMC150a. 3. Seed according to claim 2, wherein the first expression cassette comprises SEQ ID Nos. 1-4 in operable sequence. 4. Seed according to claim 2, wherein the second expression cassette comprises SEQ ID Nos. 5-8 in operable sequence. 5. Seed according to claim 2, wherein the first expression cassette comprises SEQ ID Nos. 1-4 in operable sequence and the second expression cassette comprises SEQ ID Nos. 5-8 in operable sequence. 6. A mazie plant, or parts thereof, or inbred line R583H, seed of said line having been deposited under ATCC accession No: 209671. 7. A maize plant according to claim 6, wherein said maize plant comprises a nucleic acid construct comprising two cassettes, wherein the first cassette comprises a CaMV 35S constitutive promoter operably linked to a maize alcohol dehydrogenase intron, a DNA sequence of a gene encoding a Cry1Ab protein, and a terminator functional in plants, and the second cassette comprises a CaMV 35S promoter which functions in plant cells operably linked to a maize alcohol dehydrogenase intron, a DNA sequence for a gene encoding for phosphinothricin acetyl transferase, and a terminator functional in plants, wherein the two cassettes are transcribed in the same direction, wherein the nucleic acid construct is incorporated into the seed's genome on chromosome 8, near position 117, between markers Z1B3 and UMC150a. 8. A maize plant according to claim 7, wherein the first expression cassette comprises SEQ ID Nos. 1-4 in operable sequence. 9. A maize plant according to claim 7, wherein the second expression cassette comprises SEQ ID Nos. 5-8 in operable sequence. 10. A maize plant according to claim 7, wherein the first expression cassette comprises SEQ ID Nos. 1-4 in operable sequence and the second expression cassette comprises SEQ ID Nos. 5-8 in operable sequence. 11. Pollen of the plant of claim 6. 12. An ovule of the plant of claim 6. 13. A maize plant, or parts thereof, having all the genotypic and phenotypic characteristics of a plant according to claim 6. 14. Hybrid maize seed produced by crossing a plant according to claim 6 with an inbred maize plant having a different genotype. 15. Hybrid maize plant produced by growing hybrid maize seed of claim 14. 16. A method of producing hybrid maize seeds comprising the following steps: (a) planting seeds of a first inbred maize line according to claim 1 and seeds of a second inbred line having a different genotype; (b) cultivating maize plants resulting from said planting until time of flowering; (c) emasculating said flowers of plants of one of the maize inbred lines; (d) allowing pollination of the other inbred line to occur, and (e) harvesting the hybrid seeds produced thereby. 17. Hybrids seed produced by the method of claim 16. 18. Hybrid maize plant produced by growing hybrid maize seed of claim 17. |
