Details: ROS as mediators of rapid auto-propagating systemic
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.
