Alterations in phosphoproteome under salt stress in Thellungiella roots

摘要: High salinity stress is a major environmental factor that limits plant’s distribution and productivity. An Arabidopsis-related halophyte, Thellungiella halophila, an emerging model system used for plant abiotic tolerance research. Previous studies have suggested protein phosphorylation has crucial role in the high response plants. However, phosphoproteome differential expression under halophytes not been well studied. In this report, was analyzed roots. Twenty-six putative phosphoproteins were found to changed pattern at post-translational level. Twenty of these identified by mass spectrometric analysis, including 18 upregulated two downregulated phosphoproteins. These proteins involved variety cellular processes, such as signal transduction, ROS detoxification, energy pathway, synthesis folding. While most salt-responsive are known salt-stress-related proteins, some them previously reported. Our results provide only new insights into salt responses but also good foundation further investigation salinity-regulated
