MULTIPLE SCARS, A NEW TYPE OF YEAST SCAR IN APICULATE YEASTS.

Streiblová, Eva (Czechoslovak Academy of Sciences, Prague, Czechoslovakia), K. Beran, and V. Pokorný. Multiple scars, a new type of yeast scar in apiculate yeasts. J. Bacteriol. 88:1104-1111. 1964.-A new type of yeast scar is described in apiculate yeasts: Saccharomycodes, Nadsonia, Hanseniaspora, and Kloeckera. These scars are formed on the distal poles of the cell walls in the course of vegetative reproduction, and are the cause of the formation of the apiculate form of the cells. The structure of multiple scars was studied by fluorescence microscopy and by electron microscopy on carbon replicas and isolated cell walls. The discussion deals with the importance of described cytological structures for the morphogenesis of cells and for determining individual reproductive capacity of cells, and considers some questions related to the interpretation of the development of multiple scars.
