 cultures because the steroid stimulus is difficult to present to whole
 plants. I have also looked at the paper by Hershey and Stone which
 describes a promoter which is induced by herbicides. This group work for
 DuPont and i am not sure if this will present difficulties in obtaining
 the clones.
