Description
In filamentous strains of S. cerevisiae, nitrogen stress elicits a complex morphogenetic program resulting in the transition to a filamentous form of growth. The transcription factors Flo8p and Mss11p are both required for this filamentous growth transition, in that homozygous diploid flo8(delta/delta) and mss11(delta/delta) strains do not undergo filamentation under conditions of nitrogen stress. To identify genes that are regulated either directly or indirectly by the Flo8p and Mss11p transcription factors, we have implemented DNA microarray analysis to profile changes in mRNA levels in homozygous diploid strains of the filamentous (Sigma)1278b genetic background deleted for FLO8 and MSS11, respectively, under conditions of nitrogen stress. The transcriptional profiles will identify genes with altered transcriptional levels in the deletion mutants, serving as a means to identify cellular processes and signaling pathways regulated by Flo8p and Mss11p function.
