Soil salinization is an essential environmental stressor, threatening agricultural yield and ecological security worldwide. Saline soils accumulate excessive soluble salts which are detrimental to most plants by limiting plant growth and productivity. It is of great necessity for plants to efficiently deal with the adverse effects caused by salt stress for survival and successful reproduction. Multiple determinants of salt tolerance have been identified in plants, and the cellular and physiological mechanisms of plant salt response and adaption have been intensely characterized. Plants respond to salt stress signals and rapidly initiate signaling pathways to re-establish cellular homeostasis with adjusted growth and cellular metabolism. This review summarizes the advances in salt stress perception, signaling, and response in plants. A better understanding of plant salt resistance will contribute to improving crop performance under saline conditions using multiple engineering approaches. The rhizosphere microbiome-mediated plant salt tolerance as well as chemical priming for enhanced plant salt resistance are also discussed in this review.
土壤盐渍化是一种重要的环境胁迫因素，威胁着全球的农业产量和生态安全。盐渍土积累了过多的可溶性盐，通过限制植物生长和生产力，对大多数植物造成危害。对于植物来说，有效地应对盐胁迫造成的不利影响以生存和成功繁殖是非常必要的。在植物中已经确定了多种耐盐性决定因素，并且植物盐响应和适应的细胞和生理机制已经得到了深入的描述。植物对盐胁迫信号做出反应，并迅速启动信号通路，通过调整生长和细胞代谢来重新建立细胞内的稳态。本综述总结了植物对盐胁迫的感知、信号转导和响应的研究进展。更好地理解植物的耐盐性将有助于利用多种工程方法提高作物在盐渍条件下的性能。本文还讨论了根际微生物组介导的植物耐盐性以及化学引发提高植物耐盐性的作用。
