    Salt stress impacts plant growth and development, threatening agricultural production. The Na+/H+ antiporter SALT OVERLY SENSITIVE 1 (SOS1) functions in cellular ion homeostasis through facilitating Na+ excretion and is therefore essential for plant salt tolerance. Here, we report that the transcription factors AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19 are required for salt-induced SOS1 expression and salt tolerance in Arabidopsis thaliana. ARF7 and ARF19 activate SOS1 transcription by binding to SOS1 coding region rather than its promoter. Additionally, an E3 ubiquitin ligase, CHY ZINC-FINGER AND RING PROTEIN 1 (CHYR1), interacts with and degrades ARF7 and ARF19, dampening SOS1 expression. Upon high salinity, CHYR1 expression is inhibited in plants, stabilizing ARF7 and ARF19 proteins and increasing SOS1 expression. Collectively, our study identifies a transcriptional cis-element within SOS1 coding region recognized by ARF7 and ARF19 and elucidates a molecular mechanism governing ARF7 and ARF19 protein stability and SOS1 expression during plant salt stress response.

    盐胁迫影响植物的生长和发育，威胁农业生产。Na+/H+反向转运蛋白SALT OVERLY SENSITIVE 1 (SOS1)通过促进钠离子排出，在细胞内离子稳态中发挥作用，并因此对于植物耐盐性至关重要。在这里，我们报告了拟南芥(Arabidopsis thaliana)中的转录因子AUXIN RESPONSE FACTOR 7 (ARF7)和ARF19在盐诱导的SOS1表达及植株耐盐性中是必需的。ARF7和ARF19通过结合到SOS1编码区而不是其启动子来激活SOS1转录。此外，一种E3泛素连接酶CHY ZINC-FINGER AND RING PROTEIN 1 (CHYR1)与ARF7和ARF19相互作用并降解它们，从而削弱SOS1的表达。在高盐胁迫下，植物中CHYR1的表达受到抑制，稳定了ARF7和ARF19蛋白，并增加了SOS1的表达。总的来说，我们的研究识别了SOS1编码区内由ARF7和ARF19识别的一个转录顺式元件，并阐明了在植物盐胁迫响应过程中调控ARF7和ARF19蛋白稳定性和SOS1表达的分子机制。
