Abscisic acid increases hydrogen peroxide in mitochondria to facilitate stomatal closure

Anthony E. Postiglione et al.

Summary: ABA promotes stomatal closure by inducing the accumulation of reactive oxygen species (ROS) in guard cell mitochondria. This ABA-induced ROS accumulation was observed in mitochondria, chloroplasts, cytosol, and nuclei, and was dependent on ABA receptors. Mitochondrial ROS changes play a crucial role in stomatal closure and guard cells with mitochondrial defects exhibit enhanced ABA-induced ROS accumulation and stomatal closure. This study demonstrates that ABA elevates H2O2 accumulation in guard cell mitochondria to promote stomatal closure.

Signaling mechanisms in abscisic acid-mediated stomatal closure

Po-Kai Hsu et al.

Summary: In recent years, significant progress has been made in understanding the regulatory mechanisms of ABA signal transduction, the physiological importance of basal ABA signaling in stomatal regulation, and the interactions of ABA with other stomatal signaling pathways, which provide important insights for enhancing crop drought tolerance and water-use efficiency.
