Salt stress may cause primary osmotic stress and ion toxicity, as well as secondary oxidative stress and nutritional stress in plants, which hampers the agricultural production. Salt stress-responsive transcription factors can mitigate the damage of salt stress to plants through regulating the expression of downstream target genes. Based on the soil salinization and its damage to plants, and the central regulatory role of transcription factors in the plant salt stress-responsive signal transduction network, this review summarized the salt stress-responsive signal transduction pathways that the transcription factors are involved, and the application of salt stress-responsive transcription factors to enhance the salt tolerance of plants. We also reviewed the transcription factors-regulated complex downstream gene network which is formed by forming homo- or heterodimers between transcription factors and by forming complexes with regulatory proteins. This paper provides a theoretical basis for understanding the role of salt stress-responsive transcription factors in the salt stress regulatory network, which may facilitate the molecular breeding for improved stress resistance.
盐胁迫可能会在植物中引发原发性渗透胁迫和离子毒性，以及继发性氧化胁迫和营养胁迫，从而阻碍农业生产。盐胁迫响应转录因子可通过调节下游靶基因的表达来减轻盐胁迫对植物的损害。基于土壤盐渍化及其对植物的损害，以及转录因子在植物盐胁迫响应信号转导网络中的核心调控作用，本综述总结了转录因子参与的盐胁迫响应信号转导途径，以及盐胁迫响应转录因子在提高植物耐盐性方面的应用。我们还综述了转录因子通过在转录因子之间形成同二聚体或异二聚体以及与调控蛋白形成复合物而形成的受转录因子调控的复杂下游基因网络。本文为理解盐胁迫响应转录因子在盐胁迫调控网络中的作用提供了理论基础，这可能有助于抗逆性改良的分子育种。
