Figure 1 Engineering of crop plants to be resistant to herbicides can allow agricultural strategies that are kinder to the land, with reduced need to till the earth. However, herbicides that are currently in widespread use are starting to lose effectiveness because of increases in resistant weed populations. Behrens et al. (p. 1185; see the news story by Service) describe how crop plants can be engineered to be resistant to dicamba, a well-known environmentally friendly herbicide. By transferring a bacterial gene to the crop plants, the authors engineered plants resistant to the herbicide. However, for the time being at least, weeds are not resistant and die back.
