Certain classes of herbicides act as competitive inhibitors of the photosynthetic reaction center. Genetic engineering techniques can be used to generate photosynthetic reaction centers which contain altered quinone binding sites. A genetic system for rapidly screening herbicides developed in the photosynthetic bacterium Rhodobacter capsulatus has been used to examine the effect of different s-triazine herbicides on the growth of bacteria containing reaction centers with altered quinone binding sites. Structural insights into herbicide binding have been obtained by determining the level of resistance or sensitivity to structurally related herbicides in these modified reaction centers.
