| Outline of Final Research Achievements |
Deep sea is an extreme environment for living organisms and is one of the frontiers on the earth to be explored. Do physiology and behavior of deep sea organisms exhibit circadian rhythms? To answer this question, we analyzed photosignal transduction and circadian systems in deep-sea fishes.
We used seven species of deep-sea fish kindly supplied by JAMSTEC and Kanagawa Prefectural Marine Science High School for mRNA-seq analyses on brain and retina. We identified mRNAs encoding photosingal transduction-related genes including several opsins, G proteins, and cGMP-gated channels. Furthermore, we successfully identified several clock genes.
