Salinity is a major threat to modern agriculture causing inhibition and impairment of crop growth and development.

A comprehensive understanding on how plants respond to salinity stress at different levels and an integrated approach of combining molecular tools with physiological and biochemical techniques ar… Here, we not only review recent advances in salinity stress research in plants but also revisit some basic perennial questions that still remain unanswered. ?? ??????? ? 5- ????? The environmental stress is a major area of scientific concern because it constraints plant as well as crop productivity. Plant adaptation or tolerance to salinity stress involves complex physiological traits, metabolic pathways, and molecular or gene networks. Seed germination and seedling growth are the stages most sensitive to salinity. Salinity stress limits plant growth and has a major impact on agricultural productivity. - ????? Their synthesis is correlated with stress-induced enhancement of photorespiration. To combat this issue, plants accumulate osmolytes, such as proline, sugars and polyamines in higher concentration. ???? ????? Increased Na+ uptake in plants under salinity disturbs those metabolic processes that require low Na+ and high K+, Ca2+ or both for normal functioning [8]. - ?? ????? ??? ????? - ??? ??? ????? ??? Malondialdehyde (MDA) is the main product of membrane lipid peroxidation when plants are under salt stress, and its content represents the degree of cell membrane damage. ? ??? Biotechnological approaches have improved a lot in understanding the mechanisms of salt tolerance in plants. Tolerance mechanism of plants towards salinity is still a debated question.

Mutations in these proteins can lead to heightened salt sensitivity and can limit plant growth. Plant adaptations to salinity are of three distinct types: osmotic stress tolerance; Na+ exclusion; and tissue tolerance, i.e., tolerance of tissue to accumulated Na+, and possibly Cl -.
