Imidazolinone-induced loss of acetohydroxyacid synthase activity in maize is not due to the enzyme degradation.

D L Shaner1, B K Singh.   

Abstract

Acetohydroxyacid synthase (AHAS), the first enzyme leading to the biosynthesis of valine, leucine, and isoleucine, is inhibited by different chemical classes of herbicides. There is a loss in the extractable AHAS activity in imidazolinone-treated plants. Immunological studies using a monoclonal antibody against AHAS revealed no degradation of AHAS protein in imidazolinone-treated maize (Zea mays) plants. Therefore, the loss in AHAS activity is not due to the loss of AHAS protein.
