Comparative metabolomics analysis of two Saccharomyces cerevisiae strains: the wild type and mtl1Δ, which carries a deletion of the mechanosensor Mtl1p (part-I)

ABSTRACT: To gather more in-depth knowledge of the Mtl1p mechanosensor's role in Saccharomyces cerevisiae metabolism, we conducted a comparative metabolomic analysis of two Saccharomyces cerevisiae strains: the wild type and mtl1Δ, which carries a deletion of the mechanosensor Mtl1p. Both strains were grown under normal conditions at 27°C. The most significant metabolic changes between these strains were related to amino acid metabolism, purine metabolism, and carboxylic acid metabolism.

Global phenotypic and genomic comparison of two Saccharomyces cerevisiae wine strains

Project description:The aim of this study is to phenotype a collection of 27 S. cerevisiae commercial wine strains growing within temperatures (4-45ºC) in both minimal media (SD) and synthetic must (SM) and, taking into account µmax value, to select two strains with divergent phenotype in their capacity to grow at low temperature. To confirm this differential phenotype, we design a competition between both strains during wine fermentations. As expected, at low temperature fermentation, the strain showing a good performance out-competes to the strain growing badly in cold. Finally we aimed to decipher the molecular basis underlying this divergent phenotype by analyzing the genomic, proteomic and transcriptomic differences between both strains at low temperature (15ºC) and optimum temperature (28ºC).

Comparative genomic hybridization in traditional fermentative Saccharomyces cerevisiae yeasts

Project description:We study the genetics, including microarray karyotyping using comparative genomic hybridization, to explore global changes in the genomic DNA of seven S. cerevisiae strains related to traditional fermentations of very different sources comparing to the sequenced S. cerevisiae laboratory strain (S288C). Our final goal is to determine the adaptive evolution of properties of biotechnological interest in Saccharomyces yeasts. Many copy number variations (CNVs) were observed, especially in genes associated to subtelomeric regions and transposon elements. Among the fermentation strains, differential CNV was observed in genes related to sugar transport and metabolism. An outstanding example of diverse CNV is the gen PUT1, involved in proline assimilation, which correlated with the adaptation of the strains to the presence of this nitrogen source in the media.

Fitness of natural Saccharomyces cerevisiae strains [CGH]

Project description:To characterize the ecological interactions among S. cerevisiae strains coming from the same geographical area, we examined the fitness of two natural isolates from San Giovese grapes, alone or in competition, in synthetic wine must (SWM). We performed genome-wide analyses in order to identify the genes involved in yeast competition and cooperation.

Comparative Genomic Hybridization of S. cerevisiae industrial and laboratory strains

Project description:The environmental stresses and inhibitors encounted by Saccharomyces cerevisiae strains are main limiting factors in bioethanol fermentation. Investigation of the molecular mechanisms underlying the stresses-related phenotypes diversities within and between S. cerevisiae populations could guide the construction of yeast strains with improved stresses tolerance and fermentation performances. Here, we explored the genetic characteristics of the bioethanol S. cerevisiae strains, and elucidated the genetic variations correlated with its advantaged traits (higher ethanol yield under sever conditions and better tolerance to multiple stresses compared to an S288c derived laboratory strain BYZ1). Firstly, pulse-field gel electrophoresis combined with array-comparative genomic hybridization was used to compare the genome structure of industrial strains and the laboratory strain BYZ1.

Array competitive genomic hybridization of three Saccharomyces cerevisiae strains vs. DBY8268

Project description:A six array study using total gDNA recovered from two separate cultures of each of three different strains of Saccharomyces cerevisiae (YB-210 or CRB, Y389 or MUSH, and Y2209 or LEP) and two separate cultures of Saccharomyces cerevisiae DBY8268. Each array measures the hybridization of probes tiled across the Saccharomyces cerevisiae genome.
