Nuclear Cycle

Morphology of the ascus and of the ascus cluster, as observed in carmine-stained, squash preparations of the contents of immature fruit bodies, is described with the aid of photomicrographs. Complications which raise questions regarding the applicability of the currently accepted scheme of ascus development are discussed. The function of the crozier, the mechanism of spore formation, and the correlation of nuclear behavior with ascus growth appear to have been misunderstood. It is concluded that the initial stages of ascus development involve complexities, the resolution of which may reveal unknown aspects of the nuclear cycle.

Nuclear Behavior

The nature of the "nuclear cap" of sporangial nuclei of Phytophthora infestans was studied after treatment with 1.0 N HCl, separate digestions with RNase and DNase, and staining with Feulgen and orcein stains. The results strongly support the conclusion that DNA is a major constituent of the "nuclear cap." Although they provide some supporting evidence for the conclusion that sporangia become multinucleate through migration of nuclei into them, the results also indicate that nuclear division may take place within young sporangia.
