Nuclear division phenotypes in Sporidiobolales and Trichosporonales.

ABSTRACT: During nuclear division in basidiomycetous yeasts, the mother cell nucleus migrates to the daughter cell and divides inside that cell, followed by nuclear segregation in both cells. This mode contrasts sharply with that of Saccharomyces cerevisiae, where nuclear division occurs within the mother cell without prior nuclear migration. However, the universality of this division mode across all basidiomycetous yeasts remains unclear. Accordingly, we aimed to identify basidiomycetous yeasts that undergo nuclear division inside their mother cells by observing nuclear division in 51 Sporidiobolales and 33 Trichosporonales yeasts. The phenotype of a budded cell with nuclei that exists only in the daughter cell is a key indicator of nuclear migration to the daughter cell prior to nuclear div
