Physiological and molecular principles of plant salinity stress
SUMMARY. Due to the rising problem of salinity in modern agriculture, climate changes and global food crisis, the study of salinity stress is gaining the primary importance. The mechanism of plant response to salinity includes various processes that have to be coordinated. The high salinity leads to large accumulation of toxic ions (Na+, Cl–) in plant tissues, ion disequilibrium and hyperosmolarity. Salinity stress has a negative impact on plant nutrition and mineral homeostasis, particularly for Ca2+ and K+. The recent progress in trascriptomics, genomics and molecular biology has facilitated discoveries of new salt stress-related gene families. In this review the major fundamental principles of plant salt tolerance are described. Detailed analysis of main ion transport systems and their potential role in salinity stress is presented. The future perspective gene determinants, biotechnological and genetic strategies for enhancing salt tolerance in plants are discussed.
