Reactive oxygen species (ROS) are known to accumulate during abiotic stresses, and different cellular compartments respond to them by distinctive profiles of ROS formation. In contrast to earlier views, it is becoming increasingly evident that even during stress, ROS production is not necessarily a symptom of cellular dysfunction but might represent a necessary signal in adjusting the cellular machinery to the altered conditions. ROS can modulate many signal transduction pathways, such as mitogen‐activated protein kinase cascades, and ultimately influence the activity of transcription factors. However, the picture of ROS‐mediated signaling is still fragmentary and the issues of ROS perception as well as the signaling specificity remain open. Here, we review some of the recent advances in plant abiotic stress signaling with emphasis on processes known to be affected heavily by ROS.
