Salt Adaptation Mechanisms of Halophytes: Improvement of Salt Tolerance in Crop Plants

摘要: Soil salinity is one of the most serious environmental factors that affect crop productivity worldwide. Inevitable global climate change leading to rise in sea water level would exacerbate degradation irrigation systems and contamination ground resources, which render conventional agricultural practices impossible due sensitivity crops salinity. Breeding for development salt-tolerant plants has been a major challenge complexity multigenic control salt tolerance traits. Halophytes are capable surviving thriving under at concentrations as high 5 g/L, by maintaining negative potential. Physiological molecular studies have suggested halophytes, unlike glycophytes, evolved mechanisms, such ion homeostasis through extrusion compartmentalization, osmotic adjustments, antioxidant production adaptation Employment integrated approaches involving different omics tools amplify our understanding biology stress response networks halophytes. Translation knowledge resources generated from halophyte relatives functional genomics will lead new breeds suitable saline agriculture.
