摘要： Salt stress is an abiotic stress that can be deleterious to plant growth. Currently, one third of the soil in the world is affected by salt stress. Under saline conditions, plants suffer from stress toxicity, such as ion toxicity, osmotic stress and oxidative stress, resulting in inhibition of plant growth and decreases in crop yield. Phytohormones play an important role in stress resistance in plants. Phytohormones, such as auxin, gibberellin, cytokinin, ethylene, abscisic acid and brassinosteroids, are pivotal regulators in triggering tolerance against salt stress by remodeling ion homeostasis, regulating osmolyte synthesis and activating antioxidant enzymes. Understanding how hormone function is regulated during the salt stress response will be critical for enhancing the salt tolerance of crops and can provide guidance for curbing soil salinization. Here, we review salt stress toxicity and discuss the important regulatory roles of hormones in plant adaption to salt stress. (C) 2020 Friends Science Publishers
