interpretation of freeze-fracture and thin-section results shows that fusion of the peripheral vesicle with the plasmalemma of a phytophthora palmivora zoospore occurs at several discrete sites and results in the formation and expansion of a particle-free bilayer membrane diaphragm and in the appearance of a polymorphic network of membrane-bounded tunnels , the lumina of which are continuous with the cytoplasm .
