Figure 6.
A putative model for the G protein regulated salt stress responses. In this model, RGS1 inhibit the function of Gα from releasing the Gβ subunits. The Gβ subunit interact with XLG1/2/3 to enhance the plants growth through expression of SZF1 and SZF2. Green arrows indicate positive regulation and the red one indicates inhibition. The black arrow represents processes in NaCl responsiveness.
