Salinity affects the proteomics of rice roots and leaves

While insights into the molecular mechanisms underlying salinity tolerance have been obtained from transcriptome and genome analysis, the molecules affected directly by salt and linking the extracellular stimulus to intracellular responses remain largely unknown. Protein alterations upon exogenous stimulus are vital in outlining differences that cannot otherwise be measured quantitatively. So proteomic analysis may reveal novel aspects of the plant protection mechanism from salinity. The pioneering work of Liu et al. (Proteomics 2014, 14, 1759-1775) found the differentially expressed proteins in rice roots and leaves after salt treatment, and these proteins may serve as marker group of rice resistant to salt stress. Metabolic pathways maintain cellular homeostasis and are very important for imparting stress tolerance in rice.
