| Popis: | Salinity is a major abiotic stress that impacts plant growth and development. Hylotelephium erythrostictum exhibits high salt resistance, but the mechanisms are largely unknown. In this study, we used iTRAQ technique to study the proteomic changes in leaves of H. erythrostictum under salt stress. On the basis of GO and KEGG analysis, we concluded that most DEPs were enriched in carbon metabolism, photosynthesis, plant hormone signal transduction, and energy metabolism including glycolysis/gluconeogenesis, pyruvate metabolism, and gyoxylate and dicarboxylate metabolism. Most DEPs that participate in photosynthesis were down-regulated in response to salt stress, but DEPs in energy metabolism were more up-regulated than down-regulated. In this study, changes in key proteins were analyzed to elucidate the response mechanisms of H. erythrostictum to salt stress. |
