Albersheim Model for Primary Cell-Wall Structure of Dicots

Discussion on the Albersheim Model for Primary Cell-Wall Structure of Dicots 

Since the discovery of the arabinosyloxy-L-proline-rich glycoprotein, sometimes referred to as extensin, in the primary cell-wall by Lamport,41 and its negative correlation with growth,263 the cell-wall matrix has been regarded by some as an extensin-polysaccharide complex. 

An accurate, cell-wall model must eventually take into account stresses on the cell wall, orientation of wall components, detailed structures of wall polymers, and the exact nature of chemical bonds between wall components. Present knowledge of primary cell-wall structure is too inadequate to allow any of the models currently proposed to be other than working hypotheses.
