An Investigation into the asymmetric synthesis of imidazolinones via reaction of chiral alpha-amino acid esters with nitrils

, 1991
The objective of this investigation was to develop a new synthetic method for the asymmetric synthesis of imidazolinones. This method involved an addition-cyclization reaction of an optically pure alpha-amino acid ester and a nitrile.

Systematic characterization of mutations in yeast acetohydroxyacid synthase: Interpretation of herbicide-resistance data

, 2003
Acetohydroxyacid synthase (AHAS, EC 4.1.3.18) catalyses the first step in branched-chain amino acid biosynthesis and is the target for sulfonylurea and imidazolinone herbicides, which act as potent and specific inhibitors. Mutants of the enzyme have been

Inheritance and molecular characterization of resistance to AHAS-inhibiting herbicides in rapeseed

Journal of Integrative Agriculture, 2017
Rapeseed is a very important oil crop in China; however, its production is challenging due to the absence of effective weed management strategies. This is predominantly because of a shortage of herbicide resistance genes. Acetohydroxyacid synthase (AHAS)
