This work studies the variability of Saccharomyces cerevisiae present during spontaneous fermentation Garnacha grapes’ musts from a “Pago” winery east Spain. The parameters used to select yeast are those related growth, fermentative behaviour, and influence on wine’s aroma polyphenolic composition. Yeast identification was performed by ITS analysis typed Hinfl mDNA restriction profile analysis....

Background and Purpose: The epidemiological alteration in the distribution of Candida species, as well as the significantly increasing trend of either intrinsic or acquired resistance of some of these fungi highlights the need for a reliable method for the identification of the species. Polymerase chain reaction (PCR) is one of the methods facilitating the quick and precise identification of Ca...

Numerous bacterial pathogens manipulate host cell processes to promote infection and ultimately cause disease through the action of proteins that they directly inject into host cells. Identification of the targets and molecular mechanisms of action used by these bacterial effector proteins is critical to understanding pathogenesis. We have developed a systems biological approach using the yeast...

Much of our understanding of eukaryotic mRNA decay has come from studies in budding yeast, Saccharomyces cerevisiae. The facile nature of genetic and biochemical manipulations in yeast has allowed detailed investigations into the mRNA decay pathway and the identification of critical factors required for each step. Discussed herein are standard protocols for measuring mRNA half-lives in yeast. I...
