Salt treatments and induction of senescence

Abstract

High salinity, one of the most severe abiotic stresses encountered by land plants, often results from water deficit and also induces whole-plant senescence. Thus, salt treatment provides a useful technique for stress-mediated induction of senescence in plants. In this chapter, we describe the procedures to induce senescence in Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa), using NaCl or KCl. Furthermore, we present experimental approaches to measure salt stress-induced leaf senescence.
