Project description:Array data detailing the progression of DNA replication in the yeast Lachancea waltii. L. waltii cells were pregrown in heavy isotope medium and synchronized at early S phase. They were then released into normal medium, wherein DNA replication proceeds. Replicated DNA molecules are thus of heavy-light (HL) composition as compared to unreplicated molecules, which are heavy-heavy (HH). 4 time points were taken and the percent of heavy-light DNA was determined at each time point. The heavy-heavy and heavy-light DNA molecules were separated by ultracentrifugation, differentially labeled, and hybridized to a genomic array for L. waltii. The array thus shows the progression of DNA replication.
Project description:Cadmium sulphide quantum dots (CdS QDs) are widely used in novel equipment. The relevance of the research lies in the need to develop risk assessments for nanomaterials (ENMs), using baker's yeast as model system. A whole-genome microarray experiment, performed on Saccharomyces cerevisiae (BY4742), showed how genes were regulated in response to CdS QDs.
Project description:In wine fermentation, the blending of non-Saccharomyces yeast with Saccharomyces cerevisiae to improve the complexity of wine has become common practice, but data regarding the impact on yeast physiology and on genetic and metabolic regulation remain limited. Here we describe a transcriptomic analysis of single species and mixed species fermentations.
