It was shown recently that individual cells of an isogenic Saccharomyces cerevisiae population show variability in acetic acid tolerance, and this affects the quantitative manifestation trait at level. In current study, we investigated whether cell-to-cell tolerance could be explained by observed differences cytosolic pHs immediately before exposure to acid. Results obtained with strain CEN.PK113-7D synthetic medium containing 96 mM (pH 4.5) showed a direct correlation between initial pH...
For this study, we performed a genetic screen of S. cerevisiae's deletion library for mutants sensitive to dehydration stress, with which aimed discover cell dehydration-tolerant genes.We used yeast gene set (YGDS) 4850 viable mutant haploid strains perform genome-wide the identification desiccation stress modifiers. SIP18 is among genes identified as essential cells surviving drying/rehydration process. Deletion promotes accumulation reactive oxygen species and enhances apoptotic necrotic...
The yeast Saccharomyces cerevisiae is able to overcome cell dehydration; metabolic activity arrested during this period but restarts after rehydration. genes encoding hydrophilin proteins were characterised determine their roles in the dehydration-resistant phenotype, and STF2p was found be a that essential for survival desiccation-rehydration process. Deletion of STF2 promotes production reactive oxygen species apoptotic death stress conditions, whereas overexpression STF2, whose gene...
Resveratrol is a polyphenol suggested to play protective role against ageing and age-related diseases. We demonstrate that administering low-doses of resveratrol causes ROS accumulation transcriptional changes in yeast cells human adipocytes. These gene expression depend on the oxidative transcription factor Yap1p. In particular, induces Yap1p targets, such as TRX2, TRR1 or AHP1, Yap1p-dependent mode. Under treatment, phosphorylated accumulated nucleus. knockout sensitivity, which totally...
Abstract The Saccharomyces cerevisiae type 2C protein phosphatase Ptc1 is required for a wide variety of cellular functions, although only few targets have been identified. A genetic screen in search mutations kinase–encoding genes able to suppress multiple phenotypic traits caused by the ptc1 deletion yielded single gene, MKK1, coding MAPK kinase (MAPKK) known activate cell-wall integrity (CWI) Slt2 MAPK. In contrast, mutation MKK1 paralog, MKK2, had less significant effect. Deletion...
Pleurotus ostreatus (oyster mushrooms) are the second edible mushroom produced worldwide. They have great nutritional value, their production is sustainable and uses a variety of cheap lignocellulosic substrates, including agricultural industrial wastes. This article aims to discuss various methods substrates disinfection for growing ostreatus, which one most critical step in cultivation. The main characteristics thermal pasteurization other such as microwave ultraviolet radiation been...
Summary Quiescence is an essential process in eukaryotes. Control of cell cycle progression by stress‐activated protein kinases (SAPK) critical for adaptation to extracellular stimuli. In yeast, activation the HOG MAPK signalling pathway results control at several phases. this manuscript, we describe role Hog1p modulating re‐entry into from a resting state. Cells deficient show delay entering mitotic stationary phase. Furthermore, repressible allele (Hog1AS) presents comparable behaviour...
