Abstract

In this chapter, we summarized its physiologic mechanism of salt tolerance including tissue tolerance to osmotic stress, ionic and reactive oxygen species (ROS) toxicity tolerance through accumulating compatible solutes in cytoplasm, regulating Na+/K+ homeostasis, Na+ compartmentalization and exclusion and reducing activates of enzymes for ROS detoxification stress. The methodologies for studying molecular mechanism of salt tolerance in barley were also illustrated, including quantitative trait loci (QTL) and association mapping of salt-tolerant genes, transcriptomics analysis, proteomics analysis, ionomics and metabolomics analysis. High-throughput OMICS analysis will improve comprehensive understanding of barley salt stress-induced changes in gene-protein metabolite. Furthermore, the progress of exploration and utilization of salt-tolerant barley germplasm was described in several aspects including identification of salt-tolerant germplasm, conventional breeding, marker assisted selection (MAS) breeding, and genetic transformation. The development of salt-tolerant varieties is one of the most effective ways for effective utilization of salted soil, and the exploitation and utilization of elite genetic resource is essential for developing cultivars with high salt tolerance in the future.
