Although the phenomenon of cell dedifferentiation has been known for over two and a half centuries in plants, little is known of the underlying mechanisms. Here, we have established the proteome map of Arabidopsis cotyledons and investigated the dynamic change of the cotyledon proteome in the time course of cell dedifferentiation. Among the 353 distinct genes, corresponding to 500 2-DE gel protein spots identified with high confidence, 12% have over twofold differential regulations within the first 48 h of induction of cell dedifferentiation. The distributions of these genes among different Gene Ontology categories and gene differential regulations within each of the categories have been examined. In addition, we have investigated the cotyledon phosphoproteome using Pro-Q Diamond Phosphoprotein in Gel Stain followed by mass spectrometry analyses. Among the 53 identified putative phosphoproteins, nine are differentially regulated during cell dedifferentiation. These studies have provided significant new insight into protein and phosphoprotein differential expression during cell dedifferentiation in plants.
