Approaches to Increasing Salt Tolerance in Crop Plants

摘要: Soil salinity is widely recognized as a major threat to global food security. Salinity and other abiotic stresses, which are expected be more frequent in future due disturbances climate, pose serious challenge for plant scientists ensure supply the growing world population. Several approaches have been advocated address problem, but most logical solution maintain crop productivity salt-affected areas enhance salt tolerance of plants. Due genetic physiological complexity associated with tolerance, efforts breed salt-tolerant plants met limited success. Although progress has made deciphering basis sustained needed systematically dissect utilize natural variability available germplasm improving adaptation saline environments using modern genomics tools. Wide range wild relatives, cultivars field crops, halophytes offers bright prospect discovery superior alleles improvement. With an enhanced understanding molecular mechanisms genes component traits it would possible integrated approach involving conventional breeding, analysis, marker-assisted selection, transgenic technology.
