| Outline of Final Research Achievements |
Herbicide resistance in weeds is due to changes in target enzyme. In this research, single nucleotide polymorphisms in sulfonylurea herbicide resistant Alopecurus aequalis populations in north Kyushu, Japan were clarified. Eight single nucleotide substitutions were found in Pro197 and Trp574 in the ALS enzyme. The level of resistance to SU herbicide was the highest in ALS1Thr197 and ALS1Leu574 biotypes, middle in ALS1Ser197、ALS2Ser197、ALS1Ala197 and ALS1His197 biotypes, and the lowest in ALS1Leu197 and ALS2Leu197 biotypes.
