Abstract excerpt
A specific signaling role for H(2)O(2) in Chlamydomonas reinhardtii was demonstrated by the definition of a promoter that specifically responded to this ROS. Expression of a nuclear-encoded reporter gene driven by this promoter was shown to depend not only on the level of exogenously added H(2)O(2) but also on light. In the dark, the induction of the reporter gene by H(2)O(2) was much lower than in the light....
