TranscriptomicsComparative transcriptomic analysis between a high and a low sulfite producers wine yeast strains
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 assimila...

TranscriptomicsRegulation involved in difference in nitrogen requirements of Saccharomyces cerevisiae wine yeasts in alcoholic fermentation
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 require...

TranscriptomicsA combined genetic and genomic approach uncovers molecular basis of wine yeast fermentation traits
Industrial wine yeast strains possess specific abilities to ferment under stressing conditions and give a suitable aromatic outcome. Although the fermentations properties of Saccharomyces cervisiae wine yeasts are well documented little is known on the genetic basis underlying the fermentation trait...

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

TranscriptomicseQTL linkages in wine yeasts to decipher regulatory networks in wine fermentation
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 gen...

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

TranscriptomicsSeparated and combined effects of the over-expression of a plant defensin and of a 20 mM Zn treatment on yeast.
The expression of plant defensins in Saccharomyces cerevisiae has been shown to increase tolerance to Zn of yeast (Mirouze et al., 2006; Shahzad et al., 2013). The present transcriptomic approach has been conducted to uncover the mechanism underlying this phenotype. WT yeast was compared to yeast ex...

TranscriptomicsSaccharomyces cerevisiae response to Octanoic and Decanoic acids
In this study, we present an investigation of the yeast response to the exposure to octanoic and decanoic acids, two major fermentation inhibitors. Aerobically grown cells of Saccharomyces cerevisiae U13 wine strain have been exposed to 0,05 mM of octanoic and decanoic acid. We have compared the va...
