Project description:Protein abundance changes and reversible protein phosphorylation (RPP) play important roles in regulating hypometabolism but have never been documented in overwintering frogs at high altitudes. To test the hypothesis that protein abundance and protein phosphorylation change in response to winter hibernation, we conducted a comprehensive and quantitative proteomic and phosphoproteomic analysis of the liver of the Xizang plateau frog, Nanorana parkeri, living on the Qinghai-Tibet Plateau.

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.
Project description:Potato (Solanum tuberosum L.), as an important food crop on the Qinghai-Tibet Plateau, is prone to low temperature and frost damage during the seedling stage, causing economic losses for farmers. In this study, transcriptome analyses were conducted on the leaves of Atlantic, KY130 and KY140 potato varieties following exposure to cold stress (CS). The genes StPAL(Soltu.Atl.09_2G005110) and StGAD(Soltu.Atl.11_3G000340), suggesting their involvement in the regulation of cold resistance in potato. “Flavonoid-related metabolism,” “lipid metabolism,” “amino acid metabolism,” “carbohydrate metabolism,” “nucleotide metabolism,” and “energy metabolism” might play an important role in the cold resistance of potato. Our results provided novel insights into the molecular mechanisms underlying cold resistance in potato.
