Patent abstract

The invention relates to methods and compositions for analyzing plant acetohydroxy acid synthase large subunit (AHASL) genes. In particular, the invention relates to methods for the detection of wild-type AHASL alleles and mutant AHASL alleles that encode imidazolinone-tolerant AHASL proteins. The methods involve the use of PCR amplification and novel compositions comprising allele-specific and gene-specific primers to detect the presence of mutant and/or wild-type alleles present at the individual AHASL genes of a plant. Specifically, the methods and compositions are useful for analyzing the three AHASL genes of Triticum aestivum and the two AHASL genes of Triticum turgidum ssp. durum.
