| Popis: | Salt stress negatively affects plant growth and crop productivity. As an ideal model pathway of salt tolerance in glycophyte. To better understand the molecular mechanisms of salt-response in glycophyte, 466 of 15,768 Arabidopsis thaliana proteins with the GO term of biological with known genetic background, Arabidopsis thaliana has been widely applied to disclose the process ‘response to salt stress’ were retrieved from UniPort and analyzed by bioinformatics tools of PANTHER, DAVID, KEGG, Cytoscape and STRING. Our results not only indicated the involvement of salt-responsive proteins in various pathways and interaction networks, but also demonstrated the more complicated cross-tolerances to both abiotic stresses (osmosis, water deprivation, abscisic acid, cold, heat, light and wounding) and biotic stresses (bacterium and fungus) and multiple subcellular locations of these salt-responsive proteins. Furthermore, protein activities of superoxide dismutase (SOD) and peroxidase (POD) in Arabidopsis thaliana were determined under salt, cold and osmotic stresses, which validated the hypothesis of cross-tolerance to multiple stresses. Our work will greatly improve the current knowledge of salt tolerance mechanism in glycophytes and provide potential salt-responsive candidates for promoting plant growth and increasing crop output. |
