Origin and ultrastructure of complex septa in Schizophyllum commune development

Summary

The mode of origin of cross-walls in living cells of S. commune was studied in basidiospore germinants, vegetative homokaryotic mycelium and the dikaryon of this mushroom. The de novo origin of septa in basidiospore germinants always involved annular ingrowth of cross-walls. The restriction of intercalary growth was observed in the transition from a two-celled hypha to a three-celled unit. Primary branch formation occurred in nonseptate germinants, subterminal cells of the young hypha and in the hyphal apex. Septum formation in purely vegetative homokaryotic mycelium as well as the main cross-wall of the dikaryon was also by annular ingrowth. Ultrastructure studies of the septal pore apparatus revealed no differences in those of germinants, wild-type or morphologically aberrant unilateral diploidizing strains of vegetative mycelium or in the clamp connection of the dikaryon. Simple septa of two general types prevailed in the common-A heterokaryon of S. commune.
