Project description:Gymnocypris przewalskii przewalskii is distributed in Qinghai Lake, the largest inland saltwater lake in China. It is the only Cyprinidae fish in the Qinghai Lake water system and has extremely strong adaptability to the ecological environment with high salinity. G. p. przewalskii originates from the freshwater species Gymnocypris eckloni eckloni in the Yellow River and has a freshwater subspecies, Gymnocypris przewalskii ganzihonensis, distributed in the Ganzi River. Therefore, G. p. przewalskii is considered an ideal material for studying the high salt adaptation of plateau fish. Previous studies have characterized the evolutionary basis of highland adaptation in G. p. przewalskii; however, its adaptability to highly saline aquatic environments remains elusive. In the current study, we performed physiological, histological, genomic and transcriptomic analyses to investigate the phenotypical adaptation of G. p. przewalskii to a high saline environment and the underlying genomic and regulatory bases.

Project description:Campeiostachys nutans, a dominant perennial grass in the Qinghai-Tibet Plateau, exhibits high tolerance to salt stress. The Salt Overly Sensitive (SOS) pathway is key to plant salt stress tolerance. However, the pivotal role of the SOS pathway in response to salt stress in C. nutans remains unknown. Here, we identified CnbHLH130 as a novel transcriptional activator of CnCBL10, directly binds to the G-box motif in the promoter. CnbHLH130 responds to salt stress and positively regulate salt tolerance in rice and C. nutans. Interestingly, we found CnCBL10 and CnCIPK4 interact with CnbHLH130 by a Y2H screening assay. The interactions were confirmed by split-luciferase complementation (split-LUC), Pull-down, Co-immunoprecipitation (Co-IP) and bimolecular fluorescence complementation (BiFC) assays. Moreover, CnbHLH130 enhanced the interaction between CnCBL10 and CnCIPK4, which further phosphorylate and activate Na+/H+ antiporter CnSOS1 to exclude excess cytosolic Na+ from cells in the shoots. Genetic evidence showed that CnCBL10, CnCIPK4 and CnbHLH130 coordinately regulates salt tolerance in plants. In summary, this study demonstrated that CnbHLH130 acts as a novel core component and transcriptional activator regulating CnCBL10-CnCIPK4 mediated SOS pathway, thus conferring to the salt tolerance in C. nutans. This work advanced our understandings of how an alpine plant greatly survived in the Qinghai-Tibet Plateau by concise regulation of the SOS pathway in response to salt stress.
