Role of Salt Tolerance-Related Protein (STRP) in salt stress responses in Arabidopsis thaliana

Despite its self-explicative name, the role played by the Salt-Tolerance Related Protein (STRP) in salt stress remains largely unknown. STRP has been previously characterized as a LEAlike, intrinsically disordered protein, involved in plant responses to cold stress. STRP localizes in the cytosol, nucleus and plasma membrane, and protein levels increase in stress conditions, as it has been demonstrated for cold and heat stress. In the nucleus, STRP interacts with DEK3, a chromatin-related protein that modulates DNA structures and gene expression. STRP levels are strongly increased by exogenous ABA application, and it is also involved in ABA signaling and perception. In this background, our goal was to deeply investigate the role of STRP in A. thaliana saltstress responses
