Stationary phase in the yeast Saccharomyces cerevisiae

Article Abstract:

The entry of microorganisms such as yeast Saccharomyces cerevisiae in the stationary phase or G-0 is a stress response to starvation and non-availability of essential nutrients. Such cells are characterized by regulated cessation of cell proliferation, alteration of cell wall structure, accumulation of storage carbohydrates, acquired thermotolerance, altered chromatin structure. The differentiation of the cells in stationary phase allows the cells to remain viable for extended periods, while retaining the ability to resume growth availability of nutrients.

Genetic regulation of phospolipid biosynthesis in Saccharomyces cerevisiae

Article Abstract:

Synthesis of phospholipids in the membrane of Saccharomyces cerevisiae is effected by the cis-acting promoter element, UAS (sub INO). The element act as a binding site for a heterodimeric complex to activate the transcription process that leads to the production of phospholipids. The synthesis requires the presence of inositol. Inositol is theorized to control the expression of several yeast genes.

Mechanisms and control of mRNA turnover in Saccharomyces cerevisiae

Article Abstract:

The stability or 'life' of the mRNA is one of the controls of gene expression. The turnover rates of mRNA in Saccharomyces cerevisiae was studied by inspecting degradation intermediates. The study of decay intermediates showed S. cerevisiae using several decay pathways, prominent of which is deanylated-dependent decapping which opens the mRNA to exonucleolytic digestion.
