Abstract excerpt
BACKGROUND: Reactive oxygen species (ROS) are unavoidable by-products of oxygenic photosynthesis, causing progressive oxidative damage and ultimately cell death. Despite their destructive activity they are also signalling molecules, priming the acclimatory response to stress stimuli. RESULTS: To investigate this role further, we exposed wild type Arabidopsis thaliana plants and the double mutant npq1lut2 to...
