The YEASTRACT database: an upgraded information system for the analysis of gene and genomic transcription regulation in Saccharomyces cerevisiae
Miguel C. Teixeira,Pedro T. Monteiro,Joana F. Guerreiro,Joana P. Gonçalves,Nuno P. Mira,Sandra C. dos Santos,Tânia R. Cabrito,Margarida Palma,Catarina Costa,Alexandre P. Francisco,Sara C. Madeira,Arlindo L. Oliveira,Ana T. Freitas,Isabel Sá-Correia +13 more
TL;DR: The YEASTRACT information system was revisited and new information was added on the experimental conditions in which those associations take place and on whether the TF is acting on its target genes as activator or repressor, allowing the selection of specific environmental conditions, experimental evidence or positive/negative regulatory effect.
Journal ArticleDOI
Genome-wide identification of Saccharomyces cerevisiae genes required for tolerance to acetic acid
TL;DR: The increase of potassium concentration in the growth medium was found to improve the expression of maximal tolerance to acetic acid, consistent with the idea that the adequate manipulation of nutrient concentration of industrial growth medium can be an interesting strategy to surpass the deleterious effects of this weak acid in yeast cells.
Journal ArticleDOI
Adaptive Response and Tolerance to Acetic Acid in Saccharomyces cerevisiae and Zygosaccharomyces bailii: A Physiological Genomics Perspective.
TL;DR: This review paper emphasizes genome-wide strategies that are providing global insights into the molecular targets, signaling pathways and mechanisms behind S. cerevisiae and Z. bailii tolerance to acetic acid, and extends this information to other weak acids whenever relevant.
Journal ArticleDOI
The genome sequence of the highly acetic acid-tolerant zygosaccharomyces bailii-derived interspecies hybrid strain ISA1307, isolated from a sparkling wine plant
Nuno P. Mira,Martin Münsterkötter,Filipa Dias-Valada,Júlia Santos,Margarida Palma,Filipa de Canaveira Roque,Joana F. Guerreiro,Fernando Rodrigues,Maria João Sousa,Cecília Leão,Ulrich Güldener,Isabel Sá-Correia +11 more
TL;DR: The analysis of the genome sequence indicates that strain ISA1307 is an interspecies hybrid between Z. bailii and a closely related species, paving the way to a better understanding of the genetic mechanisms underlying the generation and selection of more robust hybrid yeast strains in the stressful environment of wine fermentations.
Journal ArticleDOI
Sphingolipid biosynthesis upregulation by TOR complex 2–Ypk1 signaling during yeast adaptive response to acetic acid stress
TL;DR: It is demonstrated that appropriate modulation of the TORC2-Ypk1-sphingolipid axis in industrial yeast strains may have utility in improving fermentations of acetic acid-containing feedstocks and promoting sphingolIPid synthesis by adding exogenous long-chain base precursor phytosphingosine to the growth medium enhanced acetic Acid tolerance.
