However  the mechanisms that activate the silent genome post fertilization are poorly understood. Here  we show that transcriptional competency in zebrafish is regulated by Brd4 and p300 dependent histone acetylation. Live imaging of transcription revealed that genome activation begins at the miR 430 locus  is gradual and stochastic. We show that genome activation does not require slow down of the cell cycle and is regulated through translation of maternally inherited mRNAs. Among these  the enhancer regulators p300 and Brd4 can prematurely activate transcription and restore transcriptional competency when maternal mRNA translation is blocked  whereas inhibiting histone acetylation blocks genome activation. We conclude that p300 and Brd4 are sufficient to trigger genome wide transcriptional competency by regulating histone acetylation on the first zygotic genes in zebrafish. This mechanism is critical to initiating zygotic development and developmental reprogramming.", null, null, null, "ClickIT pulldown RNA seq   ClickIT pulldown WT with chk1 and triptolide treatment at 4h", "ClickIT pulldown RNA seq   4h chk1 trip CiT AGN001960", null, "strain:TU/AB|age:4.0|dev stage:16 cell|sex:pooled male and female|tissue:embryo|treatment:chk1 triptolide|molecule:RNA|selection:click it|sample ref:AGS001556|replicate ref:AGN001960|replicate order:1|BioSampleModel:Model organism or animal", null, null, null, null, null, null, null, null, "ClickIT pulldown RNA seq   ClickIT pulldown WT with chk1 and triptolide treatment at 4h", "AGR002644", "AGR002644", "RNA", null, null, "OTHER", "TRANSCRIPTOMIC", "unspecified", "SINGLE", "ILLUMINA", "Illumina HiSeq 2500", null, "SRP184786", null, null, "AGR002644_R1.fastq.gz", "fastq", 809282124.0, 10648449.0, "AGR002644 R1.fastq.gz", "0:76", "A:186796451;C:196752176;G:194442504;T:231268877;N:22116", 76, null, null, null, 186796451, 196752176, 194442504, 231268877, 22116, "SRX5354321", "SRS4345539", "SRA847217", "Yale_Giraldez|Genetics", "Yale_Giraldez_Group", 1, 0.8729, null, 0.13487, null, 0.91301, null, 0.89113, null, 76, null, "B", null, "usable mapping rate", "illumina", "hiseq_era", "unknown", "unknown", "unknown", "bulk", "unknown", "unknown", null, "United States", "2019-06-12", "Cleavage", "Embryo", "Embryo Imprecise", "All anatomical structures"]], "columns": ["rowid", "run.accession", "experiment.accession", "sample.accession", "study.accession", "bioproject", "study.title", "study.alias", "study.type", "study.abstract", "study.attributes", "study.PMIDs", "sample.description", "sample.title", "sample.alias", "sample.centername", "sample.attributes", "GEOsample.title", "GEOsample.dataprocessing", "GEOsample.source", "GEOsample.treatmentprotocol", "GEOsample.extractprotocol", "GEOsample.growthprotocol", "GEOsample.characteristics", "GEOsample.accession", "experiment.title", "experiment.alias", "experiment.library_name", "experiment.design_description", "experiment.library_construction_protocol", "experiment.attributes", "experiment.library_strategy", "experiment.library_source", "experiment.library_selection", "experiment.library_layout", "experiment.platform", "experiment.instrument_model", "experiment.spot_descriptor", "experiment.study_ref", "run.title", "run.attributes", "run.filename", "run.semantic_name", "run.total_bases", "run.total_spots", "run.alias", "run.read_lengths", "run.base_counts", "run.r1_length", "run.r2_length", "run.r3_length", "run.r4_length", "run.Acount", "run.Ccount", "run.Gcount", "run.Tcount", "run.Ncount", "run.experiment", "run.pool_member", "submission.accession", "submission.srasource", "submission.bioprojectsource", "seqdetective.n_mates", "seqdetective.mapping_rate.mate1", "seqdetective.mapping_rate.mate2", "seqdetective.nofeature_rate.mate1", "seqdetective.nofeature_rate.mate2", "seqdetective.sparsity.mate1", "seqdetective.sparsity.mate2", "seqdetective.pos_strand_rate.mate1", "seqdetective.pos_strand_rate.mate2", "seqdetective.readlen.mate1", "seqdetective.readlen.mate2", "seqdetective.judgement.mate1", "seqdetective.judgement.mate2", "seqdetective.judgement.reason", "platform_family", "instrument_generation", "read_bias", "selection_class", "prep_kit", "sc_or_bulk", "tech_class", "technology", "tech_variant", "submission.bioprojectsource.country", "earliest_date", "devstage_curation", "devstage_curation_coarse", "tissue_curation", "tissue_curation_coarse"], "primary_keys": ["rowid"], "primary_key_values": ["51177"], "units": {}, "query_ms": 8.913208002923056}
