Exo- and endoglucanases present in cereal coleoptile cell walls are capable of mediating hydrolysis of non-cellulosic beta-(1,3)(1,4)-glucan in situ. To assess the relationship with cell elongation, glucanase activities and the respective polypeptide abundance were determined as a function of Zea ma...
