Abstract: "Salinity is a serious problem all over the world, and is an important factor limiting agriculture production. When water availability becomes limiting for plant physiological processes under salinity, stomatal closure is its early response buffering the drop of xylem water potential and catastrophic hydraulic failure. Stomatal movement is controlled by multifaceted signaling network. Root-borne signal is considered one of these crucial factors. However, the mechanism behind the roots and shoots ‘signals’ that control the stomatal closure, in order to cope with osmotic stress remains to be poorly understood. In this review we discuss the role of root-to-shoot signal under salt stress in regulating stomatal movement."
