This research investigates how plants sense salt stress through the Salt Overly Sensitive pathway. It aims to understand the role of calcium and pH changes in activating this pathway, which is crucial for maintaining sodium balance in plants under stress conditions.
The Salt Overly Sensitive (SOS) pathway is one of the main regulatory systems responsible for Na homeostasis in plants.
The SOS pathway is activated by salt stress and comprises three core components:
SOS1, SOS2 and SOS3. SOS3 is a calcium (Ca) sensor that perceives the increase of intracellular Ca triggered by salt stress and recruits SOS2, a Ser/Thr protein kinase, to the PM.
The complex activates protein SOS1 by phosphorylation, a PM-localized Na/H antiporter that prevents the accumulation of…
