Dynamic deposition of histone variant H3.3 accompanies developmental remodeling of the Arabidopsis transcriptome.

Wollmann Heike H Holec Sarah S Alden Keith K Clarke Neil D ND Jacques Pierre-Étienne PÉ Berger Frédéric F

PLoS genetics 20120503 5

In animals, replication-coupled histone H3.1 can be distinguished from replication-independent histone H3.3. H3.3 variants are enriched at active genes and their promoters. Furthermore, H3.3 is specifically incorporated upon gene activation. Histone H3 variants evolved independently in plants and animals, and it is unclear whether different replication-independent H3.3 variants developed similar properties in both phyla. We studied Arabidopsis H3 variants in order to find core properties of this ...[more]

Dynamic Deposition of the Histone H3.3 Variant Accompanies Developmental Remodeling of Arabidopsis Transcriptome (ChIP-Seq)

Project description:In animals, replication coupled histone H3.1 can be distinguished from replication independent histone H3.3. H3.3 variants are enriched at active genes and their promoters. Furthermore, H3.3 is specifically incorporated upon gene activation. Histone H3 variants evolved independently in plants and animals and it is unclear whether different replication independent H3.3 variants developed similar properties in both phyla. We studied Arabidopsis H3 variants in order to find core properties of this class of histones. Here we present genome-wide maps of H3.3 and H3.1 enrichment and the dynamic changes of their profiles upon cell division arrest. We find H3.3 enrichment to positively correlate with gene expression and to be biased towards the transcription termination site. While heterochromatic regions are mostly depleted of H3.3, H3.1 shows a more even distribution along the genome. We report that in planta, dynamic changes in H3.3 profiles are associated with the extensive remodeling of the transcriptome that occurs during cell differentiation. We propose that H3.3 dynamics are linked to transcription and are involved in resetting covalent histone marks at a genomic scale during plant development. Similarities between plant and animal H3.3 deposition profiles indicate that H3 variants likely result from functionally convergent evolution. Analysis of 2 different histone H3 variants and transcriptome in 2 conditions.

Genome-wide comparison of H3K27me3 difference between ref6-1 and wild type Col

Project description:We demonstrate that REF6/JMJ12 (RELATIVE OF EARLY FLOWERING 6/Jumonji domain-containing protein 12) could demethylate H3K27me3. Loss of REF6/JMJ12 leads to ectopic and increased H3K27me3 of a large spectrum of genes involved in development and responses to stimuli. Examination of differences in H3K27me3 between ref6-1 and wild type Col.

High-throughput sequencing of methylated cytosine enriched by modification-dependent restriction endonuclease MspJI

Project description:In this study, we combine MspJI digestion and electrophoretic band selection with next generation high-throughput sequencing technology to detect 5-methylcytosines in Arabidopsis genome. By developing a bioinformatics workflow to attribute the CNNR sites recognized by MspJI to the reference genome, we fulfilled the systematic assessment of this method. According to the assessment, here we provide the method for generating a detailed map of plant methylome that could be feasible, reliable and economical in methylation investigation. Extracting the MspJI digested fragments, constructing sequencing library according to the Illumina protocol and sequencing with Illumina HiSeq2000. Repeatability and reproducibility studies were performed between two samples from the same individual. Specificity and sensitivity of the method was examined by comparing our data with WGBS data downloaded from GEO (GSE15922: GSM399600). **The WGBS seq data ('aerial_tissues_BS_seq_CNNR.gff') was generated from the GSM399600 Sample supplementary files ('aerial_tissues_BS_seq_alignment_batch-*.gff.gz') and was utilized to do comparative study with our MspJI-seq data including sensitivity and specificity analysis.

Mapping of Notch1 binding sites in a mouse immature T cell line

Project description:We used an immature mouse T cell line engineered to express a biotinylated form of the cleaved form of Notch1 (ICN1). ICN1-bound sites were precipitated with streptavidin-coated beads and subjected to ChIP-sequencing. Beko cells correspond to a spontaneous T lymphoma immature cell line derived from a TCRb deficient mouse. These cells were engineered to express a biotin-tagged-ICN1 and the bacterial biotin ligase BirA (Bio-ICN1) or just BirA as a control (Bio). Chromatin from both cell lines was subjected to strepatavidin-mediated precipitation and subjected to sequencing with the Illumina GAII sequencer as single end 36 base pair reads.

Mapping of Ikaros and RBPJ binding sites in the mouse T cell leukemia cell line T29

Project description:The transcription factor Ikaros represses Notch signaling. Since Ikaros and Notch treanscriptional mediator RBPJ both recognize sequences that contain the same core TGGGAA motif, it was hypothesized that Ikaros represses Notch signaling by targeting Notch response elements and competing with RBPJ for their binding. Here we used the mouse T-cell leukemia cell line T29 to compare the genomic binding profiles of Ikaros and RBPJ by ChIP-seq. The T29 cell line is derived from a Ikaros-deficient T-cell leukemia (Dumortier et al, MCB 26, 209-220, 2006) and exhibits strong Notch activation. We performed two chip-seq experiments with an anti-RBPJ antibody to map RBPJ binding sites. To map Ikaros binding sites, we engineered a T29-derived cell line that expresses a fusion protein between Ikaros and the ligand binding domain of the estrogen receptor (Ik1-ER) which is activated by addition of 4-hydroxy-tamoxifen (4OHT). We used an anti-Ikaros antibody to map the sites bound by Ik1-ER after treatment of the cells with 4OHT. Sequencing were performed with the Illumina GAII sequencer as as single end 36 base pair reads.
