Summary
A study of mitosis and meiosis in Schizosaccharomyces pombe Lindner has been carried out with the Giemsa procedure.
The pattern of mitosis in the vegetative cells of S. pombe does not differ in its main features from that of other fungi, in that it appears to be accomplished without the help of a spindle apparatus and without formation of typical metaphase plates. However, there is good evidence for the presence of centrosomes which may exert some pulling effect at the ana-telophase stages.
Meiosis in the ascogenous cells is characterized by a “leptotene”, bar-like stage followed by a tetrad formation revealing at least 3 bivalents.
