  • Publication number: 20070250946
    Abstract: Isolated polynucleotides that encode acetohydroxyacid synthase small subunit (AHASS) polypeptides, and the amino acid sequences encoding these polypeptides, are described. Expression cassettes and expression vectors comprising the polynucleotides of the invention, as well as plants and host cells transformed with the polynucleotides, expression cassettes, and expression vectors, are described. Methods of using the polynucleotides to enhance the resistance of plants to herbicides are also described.

  • Patent number: 7285701
    Abstract: This invention provides cyanobacteria as an alternative source of ahas and pds genes for plant transformations and for selectable markers. In particular, it provides for cyanobacteria, for example, Synechocystis, as a source of genes encoding herbicide insensitive proteins, and elements of genes for control of expression in plastids. Nucleic acid fragments, both the acetolactate synthase (ahas) large subunit and the ahas small subunit, were found to provide herbicide resistance. Also, the present invention provides novel Synechocystis mutant phytoene desaturase (PDS) gene conferring resistance to 4?-fluoro-6[(alpha,alpha,alpha,-trifluoro-m-tolyl)oxy]-picolinamide, a bleaching herbicide. The present invention provides improvements to method involving cyanobacteria for the screening of compounds, including a new high-through-put protocol that is a rapid and cost effective way to identify target site genes.

  • Patent number: 7083967
    Abstract: This invention provides an alternative source of ahas and pds nucleic acids for plant transformation and selection. In particular, the invention provides ahas and pds nucleic acids from cyanobacteria, for example, Synechocystis, and expression elements of these genes for control of expression in plastids. The invention further provides nucleic acids encoding the acetolactate synthase (ahas) large subunit and the ahas small subunit which were found to provide herbicide resistance to plants. The present invention also provides a novel Synechocystis mutant phytoene desaturase (PDS) gene conferring resistance to 4?-fluoro-6-[(alpha, alpha, alpha,-trfluoro-m-tolyl)oxy]-picolinamide, a bleaching herbicide. The present invention provides improved methods involving cyanobacteria for the screening of compounds, including a new high throughput protocol that is a rapid and cost effective way to identify target site genes.

  • Publication number: 20060156427
    Abstract: Disclosed herein are structure-based modelling methods for the preparation of acetohydroxy acid synthase (AHAS) variants, including those that exhibit selectively increased resistance to herbicides such as imidazoline herbicides and AHAS inhibiting herbicides. The invention encompasses isolated DNAs encoding such variants, vectors that include the DNAs, and methods for producing the variant polypeptides and herbicide resistant plants containing specific AHAS gene mutations. Methods for weed control in crops are also provided.
