Science, 1999•science.orgMicroarray-based gene expression analysis identified genes showing ploidy-dependent
expression in isogenic Saccharomyces cerevisiae strains that varied in ploidy from haploid
to tetraploid. These genes were induced or repressed in proportion to the number of
chromosome sets, regardless of the mating type. Ploidy-dependent repression of some G1
cyclins can explain the greater cell size associated with higher ploidies, and suggests ploidy-
dependent modifications of cell cycle progression. Moreover, ploidy regulation of the FLO11 …

Microarray-based gene expression analysis identified genes showing ploidy-dependent expression in isogenic Saccharomyces cerevisiaestrains that varied in ploidy from haploid to tetraploid. These genes were induced or repressed in proportion to the number of chromosome sets, regardless of the mating type. Ploidy-dependent repression of some G1 cyclins can explain the greater cell size associated with higher ploidies, and suggests ploidy-dependent modifications of cell cycle progression. Moreover, ploidy regulation of the FLO11 gene had direct consequences for yeast development.
