SOS1 gene overexpression increased salt tolerance in transgenic tobacco by maintaining a higher K +/Na + ratio

Crop productivity is greatly affected by soil salinity, so improvement in salinity tolerance of crops is a major objective of many studies. We overexpressed the Arabidopsis thaliana SOS1 gene, which encodes a plasma membrane Na +/H + antiporter, in tobacco ( Nicotiana tabacum cv. Xanthi-nc). Compare...
