Rad51 binding in meiosis after undergoing S phase with different replication programs.

Project description:ChIP-on-chip analysis of Rad51 binding in cells induced to undergo synchronous meiosis after growth in continuous nitrogen-rich conditions or after nitrogen depletion. Comparison of pat1-114 cells grown in -N and +N conditions as well as pat1-114 cells with altered Cdc45 levels in -N conditions. pat1-114 rec12M-NM-^T mutants in -N and +N conditions were also evaluated to confirm that Rad51 binding is dependent on the Rec12 transesterase.

Histone H3 lysine9 acetylation, rather than lysine4 trimethylation, marks meiotic recombination hotspots and promotes recombination initiation in fission yeast

Project description:Histone modifications are associated with meiotic recombination hotspots, discrete sites with augmented recombination frequency. For example, trimethylation of histone H3 lysine4 (H3K4me3) marks most hotspots in budding yeast and mouse. Modified histones are known to regulate meiotic recombination partly by promoting DNA double strand break (DSB) formation, but the role and precise landscape of histone modifications at hotspots remain unclear. Here, we studied hotspot-associated modifications in fission yeast and found general features: acetylation of H3 lysine9 (H3K9ac) is strikingly elevated, and H3K4me3 is not significantly enriched. Remarkably, elimination of H3K9ac reduced binding of the DSB-inducing enzyme Rec12 and DSB at hotspots. We also found that the H3K4 metyltransferase Set1 promotes DSB formation at some loci, but it restricts Rec12 binding to hotspots. These results suggest that H3K9ac rather than H3K4me3 is a hotspot-associated mark involved in meiotic DSB formation in fission yeast. S.pombe cells in a pat1-114 background were induced to enter meiosis by the haploid meiosis system, and harvested one hour after the induction. ChIP were performed using anti-H3Cter, H3K9ac, -H3K14ac and -H3K4me3 antibodies. pat1-114 rad50S rec12+-FLAG cells in a wild type, H3K9A or set1+ deletion background were induced to enter meiosis by the haploid meiosis system, and harvested five hours after the induction. ChIP were performed using anti-FLAG antibodies.

Replication origin mapping of mitotic and meiotic cells in different conditions

Project description:Identification of sites of replication initiation by copy number analysis, comparing samples before and after entry into S phase. Experiments were performed in the following strains and conditions for mitotic cells: cdc25-22 (temperature-sensitive mutation arrests cells at G2/M for synchrony, otherwise wild type), nitrogen-rich conditions; wild type, haploid and diploid, nitrogen-depletion conditions. Experiments were performed in the following strains and conditions for meiotic cells: pat1-114 diploid (temperature-sensitive mutation induces a synchronous meiosis, otherwise wild type), nitrogen-depletion and nitrogen-rich conditions; pat1-114 diploid with altered Cdc45 levels, nitrogen-depletion conditions. Comparison of samples before and after S phase entry; dye-swap experiments were performed and averaged.

Histone H3 lysine 4 trimethylation regulates RNA polymerase II promoter-proximal pause-release

Project description:Trimethylation of histone H3 lysine 4 (H3K4me3) is associated with transcriptional start sites and proposed to regulate transcription initiation. However, redundant functions of the H3K4 SET1/COMPASS methyltransferase complexes complicate elucidation of the specific role of H3K4me3 in transcriptional regulation. Here, we show that acute ablation of shared subunits of the SET1/COMPASS complexes leads to complete loss of all H3K4 methylation. H3K4me3 turnover occurs more rapidly than H3K4me1 and H3K4me2 and is dependent on KDM5 demethylases. Surprisingly, acute loss of H3K4me3 does not have detectable effects on transcriptional initiation but leads to a widespread decrease in transcriptional output, an increase in RNA polymerase II (RNAPII) pausing and slower elongation. Our study demonstrates a distinct role for H3K4me3 in transcriptional pause-release and elongation rather than transcriptional initiation.
