| Research Abstract |
Swimming behavior of the ascidian larva is controlled by photoreception of the ocellus. We have found that, however, the otx knockdown(morphant) larva, which completely lacks the ocellus, shows a photo response. By the analysis of expression sites and role of opsins other than the one expressed in the ocellus photoreceptor, we have identified melanopsin ortholog as a candidate opsin responsible for photo response in the otx morphant larva. We also found that a melanopsin gene is expressed in particular types of neurons in the brain of medaka Oryzias latipes.
