Abstract

Sethoxydim, a commercially available cyclohexanedione class herbicide by targeting the enzymatic activity of acetyl-coenzyme A carboxylase, has been found to moderately inhibit the activity of 4-hydroxyphenylpyruvate dioxygenase, a key enzyme in the biosynthesis of plastoquinones and tocopherols in plants.
