UNLABELLED In order to identify new regulators of the phosphate (Pi) starvation signaling pathway in plants, we analyzed variation in the abundance of nuclear-enriched proteins isolated from Arabidopsis roots that depends on Pi supply. We used 2-D fluorescence difference gel electrophoresis and MALDI-TOF/TOF techniques for proteome separation, visualization and relative protein abundance quantification and identification. Pi-controlled proteins identified in our analysis included components of… CONTINUE READING
