Fig. 8. Working model of ZmNSA1-mediated regulation of Na+ homeostasis.

Fig. 8

Under normal growth condition, ZmNSA1 negatively regulates the transcript levels of MHAs. Under saline-alkaline condition, Ca2+ binds ZmNSA1 and triggers its degradation via 26S proteasome, then increases the transcript levels of MHAs, thereby enhancing root H+ efflux and promoting Na+ efflux mediated by SOS1 Na+/H+ antipoter.
