Effect of Salt Stress on Plants: A Review

Abstract

Abstract

Salinity may be a major abiotic stress, limiting growth and productivity of plants in many areas of the world. The ability of plants to tolerate salt is set by multiple biochemical pathways that facilitate retention and/or acquisition of water, defend plastid functions, and maintain ion homeostasis. The ability of plants to detoxify radicals underneath conditions of salt stress is perhaps the foremost essential demand. Several salt-tolerant species accumulate methylated metabolites that play crucial twin roles as osmoprotectants and as radical scavengers. Their synthesis is correlated with stress-induced enhancement of photorespiration. In this paper, plant responses to salinity stress are reviewed with stress on physiological, biochemical, and molecular mechanisms of salt tolerance.
