Outline of Final Research Achievements

The study was conducted to elucidate the neuroendocrine systems as proximate mechanisms for pair bonding in monogamous fishes. Gene expression patterns in the brain were quantitatively compared among four species of syngnathid fishes which show the variation in mating system (i.e., monogamy and polygamy). In total, 26,383 genes were detected in the brain of a monogamous pipefish, Corythoichthys haematopterus, and used for the reference sequence for mapping the reads from the RNA-Seq. At present, the RNA-seq analysis of the brain of four species of syngnathid fishes is still ongoing.
