Abstract:
The stomatal aperture is finely tuned through guard cell reactive oxygen species (ROS) levels. Chang et al. recently elucidated the relationship between guard cell ROS homeostasis and stomatal behavior, revealing a molecular mechanism by which stomata integrate light signals to maintain ROS homeostasis in guard cells and thereby promote stomatal opening.
