Mechanisms of Paraquat Resistance

Author:

Fuerst E. Patrick,Vaughn Kevin C.

Abstract

Ten weed species have developed resistance to paraquat. Evidence supporting two potential mechanisms of resistance has been reported in several species. Resistance may be due to the rapid sequestration of paraquat thus reducing levels of paraquat at the site of action in the chloroplast; alternatively, resistance may be due to the rapid enzymatic detoxification of superoxide and other toxic forms of oxygen.
