| Organism |

| Summary |
The abundant mRNA modification N6-methyladenosine (m6A) regulates a variety of physiological processes through modulation of RNA metabolism. m6A is particularly enriched in the nervous system of several species and its dysregulation has been associated with neurodevelopmental defects as well as neural dysfunctions. In Drosophila, the loss of m6A alters fly behavior but the underlying mechanism and the role of m6A during nervous system development have remained elusive. Here we found that impairment of the m6A pathway leads to axonal overgrowth and misguidance at larval neuromuscular junctions as well as in the adult mushroom bodies. We identify the RNA binding protein Ythdf as the main m6A reader in the nervous system required for limiting axonal growth. Mechanistically, we show that Ythdf interacts directly with Fragile X mental retardation protein (Fmr1) to inhibit the translation of key transcripts involved in axonal growth regulation. Altogether, this study demonstrates that the m6A pathway controls development of the nervous system by modulating Fmr1 target selection.
