An electrophoretic karyotype for Candida albicans reveals large chromosomes in multiples.

Using field-inversion gel electrophoresis we defined an electrophoretic karyotype for the yeast, Candida albicans. The karyotype is distinct from other species of Candida and is species specific. A total of five distinct chromosomal mobility groups were observed, at least four of which are composed of a minimum of two fragments each. From the apparent sizes of these fragments relative to the large chromosomes of the morphologically related yeast Saccharomyces cerevisiae, together with the known genome size of this organism, we conclude that the karyotype is the result of the migration of intact chromosomes.
