N6 methyladenosine m6A is known to regulate mRNA decay yet how this modification promotes maternal transcript degradation remains unclear. Here we find that m6A promotes maternal mRNA deadenylation. Yet genetic loss of m6A readers Ythdf2 and Ythdf3 did not impact global maternal mRNA clearance zygotic genome activation or the onset of gastrulation challenging the view that Ythdf2 alone is critical to developmental timing. We reveal that Ythdf proteins function redundantly during zebrafish oogenesis and development as double Ythdf2 and Ythdf3 deletion prevented female gonad formation and triple Ythdf mutants were lethal. Finally we show that the microRNA miR 430 functions additively with methylation to promote degradation of common transcript targets. Together these findings reveal that m6A facilitates maternal mRNA deadenylation and that multiple pathways and readers act in concert to mediate these effects of methylation on RNA stability. | WT MZdrosha MZdicer mRNA 6 24 48 hpf pA & R0 wild type 6hpf shield + U1U2 morpholino polyA | WT MZdrosha MZdicer mRNA 6 24 48 hpf pA & R0 WT 6h shield U1U2 MO pA AGN000134 | strain:TU/AB|age:6.0|dev stage:shield|sex:pooled male and female|tissue:embryo|strain maternal:wild type|strain paternal:wild type|treatment:U1U2 morpholino|molecule:RNA|selection:pA|sample ref:AGS000122|replicate ref:AGN000134|replicate order:1|BioSampleModel:Model organism or animal | WT MZdrosha MZdicer mRNA 6 24 48 hpf pA & R0 wild type 6hpf shield + U1U2 morpholino polyA | AGR000188 | AGR000188 | RNA | RNA-Seq | TRANSCRIPTOMIC | unspecified | SINGLE | ILLUMINA | Illumina HiSeq 2000 | SRP297464 | AGR000188_R1.fastq.gz | fastq | 2315635336.0 | 30468886.0 | AGR000188 R1.fastq.gz | 0:76 1:0 | A:650669894;C:502589633;G:490937822;T:670879962;N:558025 | 76 | 0 | 650669894 | 502589633 | 490937822 | 670879962 | 558025 | SRX9666709 | SRS7865647 | SRA1169659 | Yale_Giraldez|Genetics | Yale_Giraldez_Group | 1 | 0.91636 | 0.26406 | 0.78709 | 0.51247 | 76 | B | usable mapping rate | illumina | hiseq_era | unknown | poly_a | unknown | bulk | unknown | unknown | United States | 2020-12-10 | Gastrula | Embryo | Embryo Imprecise | All anatomical structures |
