Study on the Na+/H+ flow and SOS salt resistance literature using non-invasive micro-measurement technology

Last week, Guo Nang's research group of China Agricultural University published the research results of Calcium-activated 14-3-3 proteins as a molecular switch in salt stress tolerance at Nature Communications .

Studies have revealed that 14-3-3 proteins selectively sense calcium signaling, selectively bind to and inhibit the kinase activities of SOS2 and PKS5, and synergistically regulate the activity of Na ⁺ /H ⁺ antiporter SOS1 and plasma membrane H ⁺ -ATPase, affecting Plant salt tolerance.

We have compiled a salt stress article for the SOS gene family using Non-invasive Micro-test Technology (NMT).
