    Wall formation in the saprolegniales (1970)

    Notes: Summary The primary and secondary cysts of Saprolegnia ferax and the secondary cysts of Dictyuchus sterile have a two layered wall structure, the outer layer of which bears various types of spines. These spines, and the outer wall layer are derived from preformed structures (bars) found in the cytoplasm prior to encystment. Golgi derived vesicles appear to contribute to the inner layer of the primary cyst wall of S. ferax. The outer surface of the secondary cyst walls of this species has fibrils which are not embedded in matrix material.

    Notes: Summary After a specific time of glutaraldehyde-acrolein fixation, microtubule walls appear to be composed of single 6.5–7.5 nm diameter osmiophilic subunits. Variations in the duration of glutaraldehyde-acrolein and also glutaraldehyde-osmium fixation reveal a two layered wall containing osmiophilic subunits, 4.0–4.5 nm in diameter, arranged radially, in tandem. The double-layered wall is demonstrated by microdensitometer traces. These observations are discussed in relation to previously proposed models of microtubule substructure.
