The maternal to zygotic transition is a conserved developmental progression during which thousands of maternal mRNAs are cleared by posttranscriptional mechanisms. Although some maternal mRNAs are targeted for degradation by microRNAs  this pathway does not fully explain mRNA clearance. Because the ribosome constitutes the main ribonucleoprotein complex decoding the mRNA  we investigated how codon identity and translation affect mRNA stability during development and homeostasis. Using an in vivo selection strategy  we show that the codon triplet contains translation dependent regulatory information that influences transcript decay. We find that codon composition shapes maternal mRNA clearance during the maternal to zygotic transition in zebrafish  Xenopus  mouse and Drosophila  and gene expression during homeostasis across human tissues. Codon composition affects both polyadenylation status and translation efficiency. Thus  the ribosome interprets two codes within the mRNA  the genetic code which specifies the amino acid sequence  and a conserved \u201ccodon optimality code\u201d that shapes mRNA stability and translation efficiency across vertebrates.", null, null, null, "Zebrafish tRNA at 6hpf", "tRNA AB 6h", null, "strain:TUAB|age:6hpf|dev stage:Shield|sex:pooled male and female|tissue:Whole animal|collected by:Ariel Bazzini|genotype:WT|BioSampleModel:Model organism or animal", null, null, null, null, null, null, null, null, "Zebrafish tRNAs at 6hpf", "tRNA 6hpf zebrafish", "TGIRT tRNA Library", "1", null, null, "OTHER", "TRANSCRIPTOMIC", "size fractionation", "PAIRED", "ILLUMINA", "Illumina HiSeq 2500", "<SPOT_DESCRIPTOR><SPOT_DECODE_SPEC><SPOT_LENGTH>152</SPOT_LENGTH><READ_SPEC><READ_INDEX>0</READ_INDEX><READ_CLASS>Application Read</READ_CLASS><READ_TYPE>Forward</READ_TYPE><BASE_COORD>1</BASE_COORD></READ_SPEC><READ_SPEC><READ_INDEX>1</READ_INDEX><READ_CLASS>Application Read</READ_CLASS><READ_TYPE>Reverse</READ_TYPE><BASE_COORD>77</BASE_COORD></READ_SPEC></SPOT_DECODE_SPEC></SPOT_DESCRIPTOR>", "SRP072296", null, null, "AB-tRNA_S9_R1_001.fastq.gz AB-tRNA_S9_R2_001.fastq.gz", "fastq fastq", 7860522000.0, 26201740.0, "tRNA zebrafish 6hpf", "0:150 1:150", "A:1945184302;C:2012637521;G:2171934357;T:1730625218;N:140602", 150, 150, null, null, 1945184302, 2012637521, 2171934357, 1730625218, 140602, "SRX1760541", "SRS1436386", "SRA395141", "Yale University|Giraldez Lab", "Yale University", 2, 0.04186, 0.04313, 0.00633, 0.00639, 0.96834, 0.96913, 0.53967, 0.5329, 150, 150, "T", "T", "mates < 9% mapping rate", "illumina", "hiseq_era", "unknown", "size_fractionation", "unknown", "bulk", "unknown", "unknown", null, "United States", "2016-06-17", "Gastrula", "Embryo", "Whole Organism", "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": ["40707"], "units": {}, "query_ms": 9.763394999936281}
