Table 1 Stress responsive genes and their functions
| Gene | Function | Reference |
|---|---|---|
| AtNHX1 (vacuolar Na+/H+ antiporter) | Compartmentalization of the excessive Na+ into vacuole | [28] |
| AtSOS1 (plasma membrane Na+/H+ antiporter) | Na+ extrusion from cytosol to surrounding medium | [29] |
| AtP5CS (delta-1-pyrroline-5-carboxylate synthase) | Proline biosynthesis | [30] |
| AtRD22 (responsive to dehydration) | Drought stress responsive gene | [31] |
| AtSOD1 (superoxide dismutase) | Decomposition of superoxide into hydrogen peroxide | [32] |
| AtCAT (catalase) | Decomposition of hydrogen peroxide into water and oxygen | [33] |
