4.4.1 Pectate and pectin Lyases

Differentiation of somatic cells into one of the 40 or so types of cells that plants make often, but not always, involves the elaboration of a distinct secondary cell wall. In vascular tissues, i. e. the tracheary elements (tracheids and vessels), lignin is deposited along with polysaccharides of mostly cellulose and glucuronoxylans. In other cells, such as the endodermis and epidermis, suberin is elaborated at localized regions of the walls. Certain CESA and CSL genes are expressed specifically in cells elaborating secondary walls, and several mutants have been identified with defects specifically in secondary walls.
