Yeasts, the man’s best friend
Tulha, Joana; Carvalho, Joana; Armada, Rui; Faria-Oliveira, Fábio; Lucas, Cândida; Pais, Célia; Almeida, M. J.; Ferreira, Célia1. Introduction In most cultures, bread making depends on a fermentation step. The flour leavening ability was, at first, most probably dependent on spontaneous fermentation. It became a controlled process by the maintenance of fresh innocula from one preparation to the next and this kind of environmental constraints eventually generated a particular type of yeast and bacteria biodiversity, adapted to ferment ...
Molecular characterization of Saccharomyces cerevisiae extracellular matrix and...
Carvalho, Joana; Faria-Oliveira, Fábio; Ferreria, Célia; Lucas, CândidaYeast, Saccharomyces cerevisiae, presents itself as the best studied eukaryotic model, with the possibility to modify its genetic information with highly advanced molecular techniques. This microorganism displays a high degree of similarity and conservation of processes with higher eukaryotes. Several fundamental mechanisms such as cell cycle regulation, DNA replication, recombination and repair were first unco...
Programmed cell death processes in Saccharomyces cerevisiae are altered by GUP1...
Tulha, Joana; Faria-Oliveira, Fábio; Lucas, Cândida; Ferreira, CéliaDuring the past years, yeast has been successfully established as a model to study mechanisms of programmed cell death regulation. Saccharomyces cerevisiae commits to cell death showing typical hallmarks of metazoan apoptosis, in response to different stimuli. Gup1p, an O-acyltransferase, is required for several cellular processes that are related to apoptosis development, such as rafts integrity and stability,...
