Molecular Biology of Salinity Stress: Preliminary Studies and Perspectives
Compared to anaerobiosis and heat shock, the molecular biology of salinity stress in higher plants is not well understood. Salinity tolerance is a complex trait controlled by a polygenic system (14). Genetic variability of this trait has now been recognized in a wide range of crops (1) but the genes regulating salt tolerance are yet to be identified. Consequently, plant breeders currently lack a selective marker for salinity tolerance.
