Almost all crops that are important to humans are sensitive to high salt concentration in the soil. The presence of salt in soil is one of the most significant abiotic stresses in farming. Therefore, improving plant salt tolerance and increasing the yield and quality of crops in salty land is vital. Transgenic technology is a fast and effective method to obtain salt-tolerant varieties. At present, many scholars have studied salt damage to plant and plant salt-tolerance mechanism. These scholars have cloned a number of salt-related genes and achieved high salt tolerance for transgenic plants, thereby showing attractive prospects. In this paper, the salt-tolerance mechanism of plants is described from four aspects: plant osmotic stress, ion toxicity, oxidative stress, and salt tolerance genes. This review may help in studies to reveal the mechanism of plant salt tolerance, screen high efficiency and quality salt tolerance crops.
几乎所有对人类重要的作物都对土壤中的高盐浓度敏感。土壤中盐分的存在是农业中最显著的非生物胁迫之一。因此,提高植物耐盐性并增加盐碱地作物的产量和质量至关重要。转基因技术是获得耐盐品种的快速有效方法。目前,许多学者研究了盐对植物的损害及植物耐盐机制。这些学者克隆了一些与盐相关的基因,并使转基因植物获得了高耐盐性,从而展现出诱人的前景。本文从植物渗透胁迫、离子毒性、氧化胁迫和耐盐基因四个方面阐述了植物的耐盐机制。这篇综述可能有助于揭示植物耐盐机制、筛选高效优质耐盐作物的研究。
