	       signals”
	       
	       ABSTRACT
	       Reactive oxygen species (ROS) play a multitude of
	       signaling roles in different organisms from bacteria to
	       mammalian cells. They were initially thought to be toxic
	       by-products of aerobic metabolism, but have now been
	       acknowledged as central players in the complex signaling
	       network of cells. Recent findings reveal that ROS play a
	       key role in mediating rapid long-distance
	       auto-propagating systemic signals in plants and that
	       these signals are essential for the acclimation of plant
	       to different abiotic stresses. A number of key questions
	       related to the use of ROS as signaling molecules in
	       cells, including the dynamics and specificity of ROS
	       signaling, networking of ROS with other signaling
	       pathways, and ROS waves will be addressed.
