| Research Abstract |
The relationship between gene duplication and evolution of herbicide resistance in weeds was investigated using sulfonylurea herbicide, one of acetolactate synthase inhibiting herbicides, resistant Monochoria vaginalis and M. korsakowii. These two paddy weeds are allotetraploid. Both M. vaginalis and M. korsakowii have multiple acetolactate synthase genes and single nucleotide substitution at least two acetolactate synthase genes was necessary to confer sulfonylurea herbicide resistance.
