The extensins.
The plant cell was includes a matrix which is species specific and which chages in composition during growth and development. Characterization of the protein component of the wall matrix has resulted in the purification of extensin and the genes which encode it. Analysis of the protein sequences for the extensins has provided clues about the types of interactions which may occur as the chemistry and architecture of the cell wall accommodate growth and development.
