Project description:Sequencing of mononucleosomal DNA during asynchronous mitosis in Schizosaccharomyces pombe, Schizosaccharomyces octosporus, Schizosaccharomyces japonicus and Saccharomyces cerevisiae Samples from mononucleosomal DNA from asynchronous mitosis of four species of budding (Saccharomyces cerevisiae W303-1a) and fission yeasts (S. pombe wild type 972h-, S. octosporus CBS1804, S. japonicus var. japonicus ade12- FY53) were sequenced (Illumina Genome Analyzer IIx and HiSeq 2500) using the single read and paired end protocol.
Project description:MNase-Seq and ChIP-Seq have evolved as popular techniques to study chromatin and histone modification. Although many tools have been developed to identify enriched regions, software tools for nucleosome positioning are still limited. We introduce a flexible and powerful open-source R package, PING 2.0, for nucleosome positioning using MNase-Seq data or MNase- or sonicated- ChIP-Seq data combined with either single-end or paired-end sequencing. PING uses a model-based approach, which enables nucleosome predictions even in the presence of low read counts. We illustrate PING using two paired-end datasets from Saccharomyces cerevisiae and compare its performance to nucleR and ChIPseqR.
Project description:Intact nuclei from an asynchronous population of W303 Saccharomyces cerevisiae in log-phase growth were subjected to a 16-minute DNase I digestion (0.1 U/μL) at 37 °C. DNA was then recovered, and single-end Illumina sequencing libraries were prepared using the Crawford DNase-seq method (Song and Crawford, 2010).

Project description:Intact nuclei from an asynchronous population of W303 Saccharomyces cerevisiae in log-phase growth were subjected to a 16-minute DNase I digestion (0.1 U/μL) at 37 °C. DNA was then recovered, and single-end Illumina sequencing libraries were prepared using the Crawford DNase-seq method (Song and Crawford, 2010). Two biological replicates of DNase-seq were sequenced in single-end mode on an Illumina HiSeq 2000.
