SOS3 from <i>Avicennia marina</i> Enhances Salt Stress Tolerance of <i>Arabidopsis thaliana</i>.

ABSTRACT: Abiotic stress poses a serious challenge in agriculture. Salinity inhibits crop growth and yields by disrupting ionic homeostasis and osmotic balance. One critical mechanism of salt tolerance is the activation of the Salt Overly Sensitive (SOS) signaling pathway. Investigating this pathway in halophytic plants offers valuable insights into the molecular mechanisms underlying salt stress tolerance. This study explores the structure and function of SOS3/CBL4 from the gray mangrove, Avicennia marina (AmSOS3). Sequence analysis revealed that AmSOS3 shares significant similarities with orthologs of SOS3/CBL4, including Arabidopsis thaliana (AtSOS3). All essential functional domains of SOS3, including the four EF-hands, as well as the N-myristoylation and S-acy
