Calcium-activated 14-3-3 proteins as a molecular switch in salt stress tolerance

Salinity triggers an increase in cytosolic Ca2+ concentration in plants. Here, the authors propose a model whereby 14-3-3 proteins decode this calcium signature and regulate Na+ extrusion via Ca2+-dependent regulation of PKS5 and SOS2 kinases that in turn regulate the Na+/H+ antiporter SOS1 and PM H...

Sumario:Salinity triggers an increase in cytosolic Ca2+ concentration in plants. Here, the authors propose a model whereby 14-3-3 proteins decode this calcium signature and regulate Na+ extrusion via Ca2+-dependent regulation of PKS5 and SOS2 kinases that in turn regulate the Na+/H+ antiporter SOS1 and PM H+-ATPase
