Comparison of transcriptional responses to osmotic stresses induced by NaCl and sorbitol additions in Saccharomyces cerevisiae using DNA microarray

Transcriptional responses of laboratory and brewing strains of Saccharomyces cerevisiae to osmotic stresses induced by adding either NaCl or sorbitol to their cultures were compared by clustering DNA microarray data. Our results suggest that the difference in the transcriptional responses of the two strains between NaCl and sorbitol additions is small when the dynamics of the total change in gene expression are similar.
