Meiotic prophase has been studied by both light and electron microscopy in diploid cell lines (h+/h-) of Schizosaccharomyces pombe. One wild-type and one mutant strain were used, the latter (mei4-B2) being blocked after premeiotic DNA synthesis and a

Gamma bodies, which are present in the sporangia and gametangia of Allomyces and in its spores, are interpreted as constituting vesicle generating structures. During spore cleavage the mobilization–decay of the gamma bodies leads to vesicle formati
