<br/><br/> The cell wall and extracellular matrix in higher plants include secreted proteins that play critical roles in a wide range of cellular processes, such as structural integrity and biogenesis. Compared with the intensive cell wall proteomic studies in Arabidopsis, the list of cell wall proteins identified in monocot species is lacking. Therefore, we conducted a large-scale proteomic analysis of secreted proteins from rice. Highly purified secreted rice proteins were obtained from the medium of a suspension of callus culture and were analyzed with multidimensional protein identification technology (MudPIT). As a result, we could detect a total of 555 rice proteins by MudPIT analysis. Based on bioinformatic analyses, 27.7
