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.

Project description:This experiment aims to map nucleosome positions and comparison of the same in WT NORMAL GROWTH vs WT-NUTRIENT STARVATION/isw1∆2∆ MUTANT/rsc4-∆4 MUTANT in Saccharomyces cerevisiae using a custom designed tiling array on Agilent plat form. The corresponding platform is submitted to GEO under Geo-ID GPL15842. 60mer probes with variable tiling density were designed for all the genes transcribed by RNA polymerase III. Each gene is tiled along with its 1kb downstream and upstream region with the exceptions of RPR1, SCR1, RDN5(1-6) and SNR52. Mononucleosomal DNA and size matched naked DNA was competitively hybridized to the array. Data was extracted and normalized log ratios were calculated using Agilent sofware. Normalized log2 ratio data was used in MLM to detection nucleosome positions.

Project description:We used ChIP-seq to determine the whole-genome enrichment of histone H3 threonine 11 phosphorylation (H3 T11ph) during Saccharomyces cerevisiae meiosis. S. cerevisiae SK1 cells were synchronized for meiotic entry and 3 and 4 hour meiotic samples were obtained. As H3 T11ph is dependent on the formation of meiotic double strand breaks (DSBs), a negative control ChIP-seq sample was obtained from a strain lacking DSBs (spo11-yf). Concurrently, ChIP-seq was carried out for histone H3 as a control for comparision.

Project description:Background: Recent studies have demonstrated that antisense transcription is pervasive in budding yeasts and is conserved between Saccharomyces cerevisiae and S. paradoxus. While studies have examined antisense transcripts of S. cerevisiae for inverse transcription in stationary phase and stress conditions, there is a lack of comprehensive analysis of the conditional specific evolutionary characteristics of antisense transcription between yeasts. Here we attempt to decipher the evolutionary relationship of antisense transcription of S. cerevisiae and S. paradoxus cultured in mid log, early stationary phase, and heat shock conditions. Results: Massively parallel sequencing of sequence strand-specific cDNA library was performed from RNA isolated from S. cerevisiae and S. paradoxus cells at mid log, stationary phase and heat shock conditions. We performed this analysis using a stringent set of sense ORF transcripts and non-coding antisense transcripts that were expressed in all the three conditions, as well as in both species. We found the divergence of the condition specific anti-sense transcription levels is higher than that in condition specific sense transcription levels, suggesting that antisense transcription played a potential role in adapting to different conditions. Furthermore, 43% of sense-antisense pairs demonstrated inverse transcription in either stationary phase or heat shock conditions relative to the mid log conditions. In addition, a large part of sense-antisense pairs (67%), which demonstrated inverse transcription, were highly conserved between the two species. Our results were also concordant with known functional analyses from previous studies and with the evidence from mechanistic experiments of role of individual genes. Conclusions: This study provides a comprehensive picture of the role of antisense transcription mediating sense transcription in different conditions across yeast species. We can conclude from our findings that antisense regulation could act like an on-off switch on sense regulation in different conditions.

Project description:Investigation of whole genome gene expression level changes in three S. cerevisiae Y55 mutants, compared to the wild-type strain. The UV-induced mutations enable the mutant strains to ferment high-gravity maltose faster than the WT. The mutants analyzed in this study are further described in Baerends, R.J.S., J.L. Qiu, L. Gautier, and A. Brandt. A high-throughput system for screening of fast-fermenting Saccharomyces cerevisiae strains. Manuscript in preparation. A single-dye 12-plex array chip study using double-stranded DNA prepared from messenger RNA purified from total RNA recovered from three separate Saccharomyces cerevisiae Y55 wild-type cultures and 3x three separate cultures each corresponding to a fast-fermenting UV-induced mutant (mutant 1, 2 and 3), during fermentation of high-gravity maltose at day 2. Each array on the 12-plex chip measures the expression level of 5,777 genes from Saccharomyces cerevisiae S288C with eight 60-mer probes per gene, with three-fold technical redundancy.
