In the work entitled “Comparative proteomics of Mesembryanthemum crystallinum guard cells and mesophyll cells in the transition from C3 to CAM”, we presented an interesting diurnal/diel proteomics analysis in M. crystallinum during its photosynthesis transition using the label-free method. We identified the proteins showing inverse responding patterns at each time point between the control (no transition) and treatment group (undergoing transition) in guard cells and mesophyll cells. This simple but useful method allowed us to focus on 165 and 151 proteins out of 1153 proteins in guard cells and mesophyll cells, respectively. The results facilitated understanding of plant photosynthesis plasticity at the single cell-type level.
