| Outline of Final Research Achievements |
Animals alter their behavior in response to stimulus strength. Meanwhile, detailed analysis of neural circuit is complicated circuits. So to clarify the neural mechanism of the behavioral switch for danger, we choose C. elegans as a model system, because of advantage for analysis in molecular, circuit, and behavior level. We had screened for genes required for such behavior using optogenetics and RNAi screening, and showed that a transcription factor lin-32, Drosophila atonal homolog, is required for U-turn. Especially, the lin-32 mutants fail to express a gap junction channel inx-1, showing electrical synapse defects. Our finding will clarify the atonal regulation of gap junction formation.
