Abstract
A variety of mutants which are resistant to triazine — and urea — classes of herbicides have been isolated in the cyanobacterium Synechococcus R2. A ll the mutants that have been analyzed, show some cross-resistance to different suggesting that these herbicides share a com mon binding site in photosystem II. Three psbAgenes have been identified in Synechococcus R 2. The PSB -c o p y I gene was from three mutants and used in DNA -m ediated genetic transformation. It was found that in all three mutants this gene could transfer the mutation for herbicide resistance indicating that this gene codes for the herbicide resistant protein.
