Histone H3 lysine 4 trimethylation marks meiotic recombination initiation sites.

The EMBO journal 20081211 2

The function of histone modifications in initiating and regulating the chromosomal events of the meiotic prophase remains poorly understood. In Saccharomyces cerevisiae, we examined the genome-wide localization of histone H3 lysine 4 trimethylation (H3K4me3) along meiosis and its relationship to gene expression and position of the programmed double-strand breaks (DSBs) that initiate interhomologue recombination, essential to yield viable haploid gametes. We find that the level of H3K4me3 is cons ...[more]

The conserved SUMO ligase Zip3 protein associates differentially with meiotic double-strand break sites and reveals regional variations in the outcome of meiotic recombination

Project description:In meiosis, an excess number of DNA double-strand breaks (DSBs), the initiating DNA lesion, is formed compared to the number of crossovers, one of their repair products that creates the physical links between homologs and allows their correct segregation. It is not known if all DSB hotspots are also crossover hotspots, or if the ratio between DSB and crossovers varies with the chromosomal location. Here, to systematically investigate variation in the DSB/crossover ratio, we have established the genome-wide map of the Zip3 protein binding sites in budding yeast meiosis. We show that Zip3 associates with DSB sites when these are engaged into repair by crossing over, and that Zip3 binding frequency at DSB reflects its tendency to be repaired as a crossover. We further show that the relative amount of Zip3 per DSB varies with the chromosomal location and identify chromosomal features associated with high or low Zip3 per DSB ratio. Among these is the negative regulation by proximity to a centromere and positive by the proximity to axis-associated sequences. This work opens interesting perspectives to understand the role of these extra DSB that are not frequently used for crossover and our findings may extend to mammals that have a large excess of DSB compared to crossovers.

Spp1, a member of Set1 complex, promotes meiotic DSB formation by tethering histone H3K4 methylation sites to chromosome axes

Project description:Meiotic DSB, catalyzed by the Spo11 transesterase protein and accessory DSB proteins, form in the nucleosome depleted regions (NDR) at promoters, preferentially those located on the chromosome loops that shape meiotic chromosomes, whereas the DSB proteins are located on chromosome axes at the basis of these loops. Mechanisms bridging these two chromosomal regions for DSB formation have remained elusive. Here we show that Spp1, a conserved member of the histone H3K4 methyltransferase Set1 complex, is required for normal levels of DSB formation and is associated with chromosome axes in the DSB-rich domains during meiosis. Moreover, Spp1 physically interacts with the Mer2 axis-associated DSB protein, and uses its PHD finger as a magnet to read H3K4 trimethylation close to promoters, tether these regions to chromosome axes and activate cleavage in the nearby promoter by the DSB proteins. We further show that in the absence of Spp1 or the Set1 complex, DSB are introduced at a few new sites, located in promoters of transcriptionally induced genes, suggesting another selection mechanism of preferred DSB sequences. This paper provides the molecular mechanism linking H3K4me3 to the DSB forming machinery, by the meiosis-specific specialization of Spp1 as an active member of the DSB complex and a reader of H3K4me3, and opens perspectives for the study of DSB formation at mammalian recombination hotspots that are also enriched in H3K4me3.

Transcriptomic regulation during meiosis

Project description:We studied the meiotic regulation of transcription, by comparing the mRNA level at time t=1h to t=8h after meiosis induction, to the mRNA level at time t=0h. Keywords: yeast meiotic time course, transcriptome For each time point, we measured the level of mRNA extracted at the time point to a mRNA meiotic mix composed of mRNA extracted at each time point. We normalize this ratio to the ratio measured at time t=0h and transform into log2ratios. The experiment is carried out in triplicates, from three independant cultures.
