| Abstract: | Incorporation of radioactive glucose in growing apices of Saprolegnia monoïca hyphae were examined by electron microscopic autoradiography. 3H glucose labelling indicates that dictyosomes and apical vesicles do not contain much polysaccharide and that glucan synthesis occurs at the cell surface. 14C glucose labelling shows that incorporation was chased from the cell walls during hyphal morphogenesis. |
