Article Synopsis
  • - The study explores how herbicide resistance evolves in the weed Monochoria vaginalis, which has five copies of the ALS gene, a target for sulfonylurea herbicides.
  • - Researchers analyzed several populations across Japan for herbicide sensitivity and genetic variations in ALS, discovering over 60 resistant populations with mutations linked to MvALS1 and MvALS3.
  • - The findings suggest that higher expression levels of certain ALS genes (MvALS1 and MvALS3) drive the evolution of resistance, indicating that gene expression plays a crucial role in this process.

Biotypes of Echinochloa crus-galli var. formosensis with resistance to cyhalofop-butyl, an acetyl-CoA carboxylase (ACCase) inhibitor, have been found in dry-seeded rice fields in Okayama, Japan. We collected two lines with suspected resistance (Ecf27 and Ecf108) from dry-seeded rice fields and investigated their sensitivity to cyhalofop-butyl and other herbicides.
