Salt resistant crop plants

- Three main traits are involved in salt tolerance: ion exclusion, tissue tolerance and osmotic tolerance.
- Numerous genes encoding salt tolerance traits are likely to contribute to crop performance.
- A compilation of transgenes and their effects on salt tolerance traits in crops is presented.
- Temporal and spatial control of gene-expression are often important for increasing tolerance.
- Quantifying yields in saline soils, and using proper controls in field trials, can guide crop improvement programs.
