Ein molekularer Schalter steuert die Salzstresstoleranz von Pflanzen

Salt stress is toxic to plants and diminishes crop yield. High Na+ triggers Ca2+ signals with specific localization, intensity, and duration in a dose dependent manner. These signals are translated into enhanced Na+ exporter activity via the Salt-Overly-Sensitive (SOS) pathway, vacuolar Na+ sequestration, and enhanced formation of paracellular ion barriers. All of these mechanisms are crucial for facilitating plant tolerance to soil salinity.
