Potential Breeding Strategies for Improving Salt Tolerance in Crop Plants

Abstract Salinity is one of the significant abiotic stresses that negatively affect plant production processes, growth, and development, which ultimately reduce yield. Plants adapt specific mechanisms to withstand saline conditions activate diverse salt tolerance genes counter osmotic oxidative induced by salinity. Genetic development in salinity quite complex, while advancement has made less progress than expectation over past few decades. Generating an explosion genetics- genomics-related information technology recent decades pledge deliver innovative advanced resources for potential tolerant genotypes. Despite considerable defining primary mechanisms, main obstacles are yet be solved translation incorporation resulting molecular knowledge into breeding activities. Diverse approaches proposed enhance efficacy increase productivity environments. Understanding genetics a difficult task because multiple pathways involved. Important advances tools methods updating manipulating genomics provide detailed insights dissect mechanism accomplished goals. Genome-wide analyses (GWA) identify SNP variations functional effects appear way future developing salinity-tolerant plants. Gene discovery manipulate underlie complex phenotype methods, identification genes, QTL, association mapping, linkage, genomics, such as transcript identifying proteins related salinity, necessary. The present analysis also discussed some opportunities challenges, focusing on strategies used conjunction with other crop growing elite salt-tolerant lines.
