Advances in Research on 4-Hydroxyphenylpyruvate Dioxygenase (HPPD) Structure and Pyrazole-Containing Herbicides

Abstract

4-Hydroxyphenylpyruvate dioxygenase (HPPD), a target for green herbicide discovery, has recently attracted a large number of famous scientists attention owing to controlling efficacy of resistant weeds. The structures of HPPD, inhibitors binding sites, mode of action and their metabolites are summarized. The current commercial and developing pyrazole-containing herbicides of HPPD are analyzed. Based on combining theory and practical application, a direction to find or design a new inhibitor is also oriented.
