  • Herbicide-Resistant AHAS-Mutants and Methods of Use
    Publication number: 20120060243
    Abstract: The invention provides transgenic or non-transgenic plants with improved levels of tolerance to AHAS-inhibiting herbicides. The invention also provides nucleic acids encoding mutants of the acetohydroxyacid synthase (AHAS) large subunit, expression vectors, plants comprising the nucleic acids encoding the AHASL subunits containing one, two, or more mutations, plants comprising such AHASL subunit mutant nucleic acids, methods for making and using the same, and methods of controlling weeds.

  • Nucleic acid molecules encoding proteins essential for plant growth and development and uses thereof
    Publication number: 20040191850
    Abstract: Nucleotide sequences are isolated from Arabidopsis thaliana that code for proteins essential for plant growth and development. The essentially of the proteins may be exploited by recombinantly expressing the proteins and using them in screening assays to identify compounds that interact with or inhibit the proteins and are therefore potential herbicides.

  • Maize orthologues of bacterial RecA proteins
    Patent number: 6388169
    Abstract: The present invention provides methods and compositions relating to altering RecA content and/or composition of plants. The invention provides isolated nucleic acids and their encoded proteins that are homologous to bacterial RecA genes. The invention further provides recombinant expression cassettes, host cells, transgenic plants, and antibody compositions. The plant recA polynucleotides and their cognate products are useful for gene targeting in maize and other plant species and for use as a molecular marker.
