Abstract
Nuclear division inCandida albicans during budding and blastospore formation is described. Classic mitotic division as it occurs in the higher ascomycetes is not seen. Instead, the semi-lunar (crescentic) chromatinic material in the nucleus increases so as to fill the nuclear vesicle, often assuming a toroid-like aspect. The nucleus then divides into two crescentic masses one of which migrates to the daughter cell. No external centriole or spindle apparatus could be observed. No chromosomes could be resolved. Nuclear division in the mold phase duplicated that found in the yeast phase. Colchicine treatment of yeast phase cells resulted in the appearance of large polynucleate and polyploid cells in one strain ofC. albicans.
