Global transcriptional response of wild type and transcription factor deletion strains of Saccharomyces cerevisiae to the environmental stress of cold shock and subsequent recovery


ABSTRACT: Previous studies on the global transcriptional response of budding yeast, Saccharomyces cerevisiae, to cold shock have revealed that the response can be divided into a set of early response genes (after 15 minutes to 2 hours of cold temperatures) and late response genes (after 12 to 60 hours of cold temperatures). The late response genes include the ESR genes induced by many environmental stresses and are regulated by the Msn2 and Msn4 transcription factors, as they are during other environmental stresses (Kandror et al. 2004 PMID:15053871; Schade et al. 2004 PMID:15483057). However, the transcription factors responsible for the induction of the early response genes, the overall regulatory mechanism governing this early response, and the transcriptional response to recovery after cold shock remain largely unknown. Thus, we measured the early transcriptional response of S. cerevisiae to cold shock and subsequent recovery using DNA microarrays. To determine which transcription factors were responsible for these changes in expression, the same cold shock and recovery microarray experiments were then performed on six strains individually deleted for the transcription factors Cin5, Gln3, Hap4, Hmo1, Swi4, and Zap1.
