Plants are constantly challenged by different environmental biotic and abiotic stresses, which cause substantial losses in fruit yield and quality. A common consequence of such stresses is the accumulation of reactive oxygen species (ROS) and the establishment of a ROS-mediated oxidative stress leading to metabolic damage and finally to cell death. There is recent evidence suggesting that even under stress conditions ROS production is not only a symptom of cellular dysfunction but could also act as second messenger in adjusting the cellular machinery to the altered conditions.
