The otx2 gene encodes a transcription factor (OTX2) important in the development of the mind and sensory techniques. Especially, OTX2-positive
cells are associated with axons in the olfactory method of mice and otx2 is upregulated in odour-exposed zebrafish, indicating a feasible part in olfactory imprinting. In this examine, otx2 was utilised as a candidate gene to investigate the molecular mechanisms of olfactory imprinting to settlement cues in the coral
reef anemonefish, Amphiprion percula. The A. percula otx2 (Ap-otx2) gene was elucidated, validated, and its expression examined in settlement-stage A. percula by exposing them to behaviourally pertinent olfactory settlement cues in the initial 24 hours publish-hatching, or day-to-day throughout
the larval stage. In-situ hybridisation unveiled expression of Ap-otx2 throughout the olfactory epithelium with increased transcript staining in odour-exposed settlement-phase larval fish in contrast
to no-odour controls, in all scenarios. This implies that Ap-otx2 might be included in olfactory imprinting to behaviourally related settlement odours in A. percula.
