Formation of singlet oxygen ((1)O2) has been implicated with damaging photosystem II (PSII) that needs to undergo continuous repair to maintain photosynthetic electron transport. In addition to its damaging effect, (1)O2 has also been shown to act as a signal that triggers stress acclimation and an enhanced stress resistance. A signaling role of (1)O2 was first documented in the fluorescent (flu) mutant of Arabidopsis It strictly depends on the chloroplast protein EXECUTER1 (EX1) and happens… CONTINUE READING
