Transcriptomic analysis of silver-resistant Saccharomyces cerevisiae mutant obtained by evolutionary engineering

ABSTRACT: Silver-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering method. Briefly, genetic diversity in reference strain, CEN.PK.113-7D, was increased by ethyl methane sulfonate (EMS)-mutagenesis. The mutant population was passaged several times in gradually increasing silver stress. Several mutant individuals were selected from the final population. Among selected mutant individuals, one of them was much more resistant to silver stress than the reference strain, called as 2E. Whole-genome transcriptomic analysis was performed to identify the silver resistance mechanisms in the silver-resistant mutant strain.

Transcriptomic analysis of a NaCl-resistant Saccharomyces cerevisiae mutant obtained by evolutionary engineering

Project description:NaCl-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering. EMS mutagenized culture was used as the initial population for the selection procedure. Gradually increasing levels of NaCl stress was applied through 40 successive batch cultivations. The reference strain could not grow even at 0.85 M NaCl whereas this mutant was shown to be resistant up to 1.45 M NaCl concentration. Whole-genome microarray analysis was used to identify the NaCl resistance mechanisms by comparing NaCl-resistant mutant strain and the reference strain in the absence of NaCl stress.

Transcriptomic analysis of an iron-resistant Saccharomyces cerevisiae mutant obtained by evolutionary engineering

Project description:Iron-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering selection strategy. The mutant obtained “M8FE” is much more resistant to iron stress than the reference strain which was used to select this mutant. Mutant can resist up to 35mM Iron* stress whereas the reference strain cannot. Whole-genome microarray analysis might be promising to identify the iron resistance mechanisms and stress response upon high levels of iron in the yeast cells. Iron-resistant mutant is also cross resistant to Cobalt, Chromium and Nickel but sensitive to Zinc. * refers to [NH4]2[Fe][SO4]2 and FeCl2.

Transcriptomic analysis of a Saccharomyces cerevisiae mutant with extended chronological life span

Project description:A Saccharomyces cerevisiae mutant with extended chronological life span was obtained by using an evolutionary engineering strategy, based on successive batch cultivation under gradually enhanced caloric restriction. The mutant strain SRM11 was selected which had about 50% longer life span than the reference strain. Whole-genome transcriptomic analysis of SRM11 with respect to the reference strain was performed to identify differences in gene expression levels between the two strains.

Evolutionary Engineering and Transcriptomic Analysis of Phenylethanol-resistant Saccharomyces cerevisiae

Project description:Phenylethanol-resistant S. cerevisiae mutants were obtained by using evolutionary engineering strategy. Briefly, a chemically mutagenized culture was used as the initial population for the selection procedure. Gradually increasing levels of phenylethanol stress was applied through 56 successive batch cultivations. Individual mutants were selected from the final population. The mutant with the highest phenylethanol resistance could resist up to 3 g/L phenylethanol concentrations. Whole-genome transcriptomic analyses of the phenylethanol-resistant mutant strain and the reference strain were performed by using DNA microarray technology, in the absence of phenylethanol stress. Agilent yeast DNA microarray systems were used for whole-genome transcriptomic analyses of the reference strain and the selected phenylethanol-resistant mutant. Three replicates of each culture were grown in 100 mL yeast minimal medium using 500 mL flasks, at 30Â°C and 150 rpm. Cells at logarithmic phase of growth (~1.0 OD600) were used for total RNA isolation.

The reference Saccharomyces cerevisiae strain and the iron-resistant mutant were grown in minimal medium to an Optical Density (OD600) of 1.00 which correspond to the logarithmic growth phase of the yeast cells. Cultures were harvested and whole RNA isolation was carried out. The experiment was repeated three times.
