Enantioselective phytotoxicity of the herbicide imazethapyr and its effect on rice physiology and gene transcription.

Environ. Sci. Technol. 45(16) , 7036-43, (2011)

Imazethapyr (IM) is a chiral herbicide and a widely used racemic mixture. This report investigated the enantioselectivity between R- and S-IM in rice and explored its causative mechanism at the physio...

Molecular mechanism of enantioselective inhibition of acetolactate synthase by imazethapyr enantiomers.

J. Agric. Food Chem. 58(7) , 4202-6, (2010)

Chiral compounds usually behave enantioselectively in phyto-biochemical processes. Imidazolinones are a class of chiral herbicides that are widely used. They inhibit branched-chain amino acid biosynth...

Enantioselective phytotoxicity of the herbicide imazethapyr on the response of the antioxidant system and starch metabolism in Arabidopsis thaliana.

PLoS ONE 6(5) , e19451, (2011)

The enantiomers of a chiral compound possess different biological activities, and one of the enantiomers usually shows a higher level of toxicity. Therefore, the exploration of the causative mechanism...
