Ectopic expression of Arabidopsis thaliana Na+(K+)/H+ antiporter gene, AtNHX5, enhances soybean salt tolerance
Drought and salt stresses are the two major factors influencing the yield and quality of crops worldwide. Na+(K+)/H+ antiporters (NHXs) are ubiquitous membrane proteins that play important roles in maintaining the cellular pH and Na+(K+) homeostasis. The model plant Arabidopsis potentially encodes six NHX genes, namely AtNHX1 to 6.
