Protein phosphorylation is one the most important post-translational modifications in plants and a key event in the regulation of protein activity. The reversible phosphorylation/dephosphorylation steps can modulate signaling processes, control enzymatic activity, modify sub-cellular structures and regulate gene expression. Monitoring the phosphorylation status of the leaf proteins from plants grown in different CO2 concentrations may contribute to a better understanding of the post-translational processes that occur during photosynthesis and carbon assimilation. The goal of this project is to acquire and process phosphoproteomics data using a well established computational pipeline developed by the De Smet group at the VIB-UGent-Institute for Plant Systems Biology. Global leaf phosphoproteome analysis will be carried out using a combination of different enrichment strategies followed by MS data acquisition according to a previously established analytical method. The stoichiometry of protein phosphorylation will be estimated after plant cultivation under controlled conditions under a dedicated pipeline. Apart from the scientific results, the research mission will assist in the implementation of a phosphoproteome sample processing strategy and a data analysis workflow that may be used in any propospective research project from the group and/or from collaborators.
