Transcriptomic analysis of the metabolic impact of higher oligopeptide assimilation mediated by horizontally acquired oligopeptide transporters Fot1/2 in wine strains.

ABSTRACT: To assess the impact of a higher oligopeptide assimilation mediated by Fot1/2, oligopeptides transporters acquired by HGT on wine yeast cell metabolism in winemaking conditions,we carried out a comparison of transcriptomic profiles of the wine wild type strain 59A and the deletion mutant of FOT1/2 genes during exponential growth. Two strains (59A and 59A FOT-deleted) at 2 released CO2 time point (5g/L and 10g/L) are analyzed. Each condition are in quadriplicate.

In the past decade, horizontal gene transfer (HGT) has emerged as a major evolutionary process that has shaped the genome of Saccharomyces cerevisiae wine yeasts. We recently showed that a large Torulaspora microellipsoides genomic island carrying two oligopeptide transporters encoded by FOT genes increases the fitness of wine yeast during fermentation of grape must. However, the impact of these genes on the metabolic network of S. cerevisiae remained uncharacterized. Here we show that Fot-media ...[more]

Impact of PDR8 allelic variation on yeast transcriptome profile in wine fermentation condition.

Project description:An eQTL analysis show that mutations in PDR8 gene in 59A strain versus S288c could trigger expressions variations of QDR2. In order to confirm this result and highlight other gene expression variations associated to PDR8 allelic variation, we performed an allele switch of PDR8 in 59A background (59A PDR8-S288c) and compared the transcriptomic profile of this strain to 59A. The analysis was performed in wine alcoholic fermentation conditions in stationary phase during nitrogen starvation and in alcoholic stress. PDR8 allelic variation: 9 non synonymous SNP (S288c->59A) 9(K->T), 17(S->L), 79(P->S), 198(G->D), 263(H->R), 267(T->S), 371(L->F), 550(A->G), 601(I->V). 6 transcriptomic profiles were performed with Agilent mono-color array: 3 hybridizations were performed for each strain corresponding to 3 biological replicated samples. Using mono-color array, the intensity was used after normalization to calculate logarithm base 2 of expression ratios.

Comparative transcriptomic analysis of an evolved and an ancestral wine yeast strains presenting differences in the bioconversion of higher alcohols to acetate esters

Project description:An evolved strain (ECA5) presented two successive yields of bioconversion of higher alcohols to acetate esters, while its parental strain (EC1118) had a constant yield through the fermentation. Transcriptomic analysis was performed during wine fermentation in SM330 containing 8mg/L phytosterols, at 35 g/l and at 70 g/l of CO2 released. For ECA5, this corresponds to a sample before and one after the change of bioconversion yield. This analysis helped us to understand the different management of lipid source by the evolved strain, which is probably linked to a greater availability in acetyl-CoA. Two strains (EC1118 and ECA5) were compared during wine fermentation at 2 released CO2 time point (35g/L and 70g/L). Each condition is in triplicat.

Impact of nutrient unbalances on wine alcoholic fermentation: nitrogen excess enhances yeast cell death in lipid-limited must

Project description:In this work we evaluated the impact of nutritional unbalances, as lipids/nitrogen unbalances, on wine yeast survival during alcoholic fermentation. We showed that lipids limitations (actually ergosterol limitation) lead to a rapid loss of viability during the stationary phase of fermentation but that cell death rate is strongly modulated by the amount of nitrogen sources. Yeast survival is reduced when an excess of nitrogen is available in lipid-limited fermentations. Such rapid dying yeast cells fermenting with high nitrogen level and lipids-limited amounts displayed a low storage of carbohydrate trehalose and glycogen compared to nitrogen limited cells. Consistently, examination of the cells stress response using an HSP12 promoter-driven GFP expression showed that lipids limitation triggered a weaker stress response than nitrogen limitation. We examined the involvement of nitrogen signalling pathway in the triggering of cell death using a sch9-deleted strain. We showed that deletion of SCH9 restored a high yeast viability indicating that the signaling pathway acting through Sch9p is involved in the enhanced cell death triggered by nitrogen excess. In addition we showed that various nitrogen sources provoked cell death but that histidine and proline did not trigger a similar effect. As a whole our data indicate that lipids limitation does not elicit a transcriptional program leading to a stress response which protects yeast cells and that nitrogen excess triggers cell death through a modulation of this stress response, but not by HSP12. These results point a potential negative role of nitrogen in fermentation which has until now never been described and taken into account in the management of alcoholic fermentations. 2 conditions with 2 biological replicates compared: 59A and 59A-Sch9

eQTL linkages in wine yeasts to decipher regulatory networks in wine fermentation

Project description:We performed here the transcriptomic profile of 44 segregants from a cross between S288c and 59A (a spore of EC1118 strain). The analysis was performed in wine fermentation condition in stationary phase during nitrogen starvation and in alcoholic stress. These data, associated with an individual genotyping by Affymetrix array allow us to highlight genetic variations involved in perturbation of regulatory network and fermentative behavior. 56 transcriptomic profiles were performed with Agilent mono-color array. 6 hybridizations were performed for each parental strains: 3 technical replicates for 2 biological replicated samples (59As1 and 59As5; S288Cs1 and S288Cs5). One hybridization was performed for each of the 44 segregants. Using mono-color array, the logarithm base 2 of intensity was directly used after normalization.

Regulation involved in difference in nitrogen requirements of Saccharomyces cerevisiae wine yeasts in alcoholic fermentation

Project description:The objective of this work is to identify, in enological condition, differences in transcriptomic regulation that may explain the differences in strains fermentation properties. For this, we compared the global expression patterns of 8 Saccharomyces cerevisiae strains with different nitrogen requirement (L2868, 4CAR1, Fermiflor, Zymasil, MTF1782, 7013, K1M, EC1118). The transcriptome was analyzed on cells fermenting in a nitrogen limited medium containing 100mg.l-1 assimilable nitrogen (SM100) and harvested at stationary phase (45g/L of CO2 produced and corresponding to 6% ethanol). At this stage the strains exhibited differences in fermentation rates. Moreover, the transcriptome was shown to be rather stable at this stage since growth was stopped for all cells and nutrients have been depleted (Rossignol et al. 2003). Eight strains with different nitrogen requirement were analyzed (L2868, 4CAR1, Fermiflor, Zymasil, MTF1782, 7013, K1M, EC1118). This analysis includes two biological replicates for each strain.

Transcriptomic analyses of three wine yeast strains duting their response to nitrogen availability

Project description:A time-course transcriptomic experiment was performed in three geographically different wine yeast strains in order to test differences in gene expression as response to different nitrogen availability mRNA amounts for different wine yeast strains at different nitrogen availability was determined along the fermentation of a syntethic must. mRNA determinations were made at different fermentation stages (12, 24, 36 and 96 h after innoculation) Please note that there are two replicates per each stage (i.e. two raw data files per each sample; R1.txt and R2.txt) and the data were combined to generate the normalized data for each stage (i.e. sample).

Comparative transcriptomic analysis between a high and a low sulfite producers wine yeast strains

Project description:The goal of this study was to compare the expression level of the whole genome of two wine yeast strains highly differing in their sulfite production (High producer strain: 10281A; Low producer strain: 1764A). Conditions maximizing SO2 production were selected: nitrogen rich media (425 mg/l assimilable nitrogen) and low temperature (16°C). This transcriptomic analysis was performed during the sulfite production phase, just after the entry in stationary phase. This analysis is part of a global work, aiming at the identification of the molecular basis of sulfite production by wine yeasts through physiologic, transcriptomic and genetic studies. Two strains compared in the same conditions with biological replicates following a dye-swap design.
