Understanding the fate of peroxynitrite in plant cells - From physiology to pathophysiology

► To date only few published reports describe the ONOO− presence in vivo in plants. ► Interestingly, ONOO− itself is not so destructive for plant cell metabolism. ► The review is focused mainly on the search for potential functions of ONOO− in plants. ► The sense of protein nitration as a new paradigm in signal modulation is discussed.
