Questions Evidence for in situ synthesis of cell wall microfibrils Indirect evidence for a role of hydrolytic enzymes in wall synthesis Possible Implications Questions 1. EM tends to demonstrate that wall microfibrils are not carried to wall synthetic loci in apical vesicles. Vesicles seem to be transporters of amorphores matrix materials. Heteropolysaccharides Mannoproteins etc.
Fungal hyphae have intrinsic ability to execute carefully controlled dissolution of own wall.
Possible implications 1. Fungal cell wall synthesis depends on a gradient of cell wall synthesis accompanying a gradient of cell wall lysis. For this to occur lytic and synthetic components and machinery must be compartmentalized.
