    摘要: A method for the rapid isolation and identification of the DNA sequence of transposable element-tagged genes is provided. The method comprises a modified AFLP approach using a transposable element-anchored amplification to identify and clone an amplification product that is associated with a mutant phenotype. Once cloned, the amplification product of interest may be used to screen a cDNA library directly or may be sequenced and compared to available databases for sequence homology. A modification of this approach provides a method for the identification of the location of an additional type of insertion event into genomic DNA, more specifically transgene insertion into the genome of a host organism.

    摘要: The invention provides nucleic acids encoding mutants of the acetohydroxyacid synthase (AHAS) large subunit comprising at least two mutations, for example double and triple mutants, which are useful for producing transgenic or non-transgenic plants with improved levels of tolerance to AHAS-inhibiting herbicides. The invention also provides expression vectors, cells, plants comprising the polynucleotides encoding the AHAS large subunit double and triple mutants, plants comprising two or more AHAS large subunit single mutant polypeptides, and methods for making and using the same.
