Cellulose Biosynthesis Inhibitor Herbicides
Cellulose biosynthesis inhibitor (CBI) herbicides are a small group of chemically unrelated compounds including the herbicides dichlobenil, isoxaben and flupoxam (Sabba and Vaughn 1999; Fig. 1). In addition, the auxinic-type herbicide quinclorac may have a second site of action in monocots that affects cellulose biosynthesis (Koo et al. 1996, 1997). Although they are a rather small group of compounds in relation to all of the herbicides, they have several qualities that make them quite important. For example, the lack of field resistance to these compounds and a site of action not shared by mammals make them an important group in terms of resistance management and approval by government agencies concerned with toxicological issues. Moreover, they appear to be useful tools to unravel the complexities of the plant cell wall and, more specifically, the production of cellulose.
