(Submitter supplied) Transcriptional regulation of branched-chain amino acid metabolism in Saccharomyces cerevisiae involves two key regulator proteins, Leu3p and Gcn4p. Leu3p is a pathway-specific regulator, known to regulate six genes involved in branched-chain amino acid metabolism and one gene in nitrogen assimilation. Gcn4p is a global regulator, involved in the general response to amino acid and purine starvation. more...

(Submitter supplied) Aerobic, glucose-limited chemostat cultures of Saccharomyces cerevisiae grown with six different nitrogen sources were subjected to transcriptome analysis. The use of chemostats enabled an analysis of nitrogen-source-dependent transcriptional regulation at a fixed specific growth rate. A selection of preferred (ammonium and asparagine) and non-preferred (leucine, phenylalanine, methionine and proline) nitrogen sources was investigated. more...

(1992) Genetics 130, 51-58) and t=0 time point samples were harvested (250 ml). The remainder of the medium was supplemented with 10 mM glycine incubated at 30oC and samples (250 ml) harvested at 20, 40 and 80 minutes. All cells were harvested by rapid centrifugation at room temperature then flash frozen in liquid nitrogen. more...

(Submitter supplied) Rsf1p is a putative transcription factor required for efficient growth using glycerol as sole carbon source but not for growth on the alternative respiratory carbon source ethanol. We use microarrays to determine the differences in the transcriptional program between the Δrsf1 mutant and the wild type during respiratory growth on glycerol as well as the transition to growth on glycerol as sole carbon source. more...

(Submitter supplied) Expression analysis of BY4716(isogenic to S288c) and a wild isolate collected by R. Mortimer. Each strain was grown in culture 6 independent times and RNA from each culture was isolated. Each of these RNA samples was subjected to a dye-swap pair of arrays (except the "RM11" sample, which only got one array). All arrays used the same pool of reference BY4716 sample. In sample titles, "BY" alone signifies the reference sample and all other strings represent independent cultures. more...

(Submitter supplied) In response to limited nitrogen and abundant carbon sources, diploid Saccharomyces cerevisiae strains undergo a filamentous transition in cell growth as part of pseudohyphal differentiation. Use of the disaccharide maltose as the principal carbon source, in contrast to the preferred nutrient monosaccharide glucose, has been shown to induce a hyper-filamentous growth phenotype in a strain deficient for GPA2 which codes for a Galpha protein component that interacts with the glucose-sensing receptor Gpr1p to regulate filamentous growth. more...

(Submitter supplied) In this study, using DNA microarray analysis, we compared the comprehensive expression profiles of two yeast trains, i.e, the previously obtained ethanol-adapted yeast strain and the parental strain as control (FY834), under the ethanol stress condition (YPD medium contained 10% ethanol). As a result, we identified certain genes and functional categories of the genes that are possible involved in growth under the ethanol stress condition.
