| Outline of Final Research Achievements |
Crustacean reproduction is principally regulated by vitellogenesis- inhibiting hormone from the X-organ/sinus gland neurosecretory system in the eyestalks. On the other hand, the roles of peptide/protein hormones that expressed in peripheral tissues are still unclear. In this study, we focused on hormonal factors of which transcripts were found by the transcriptome analysis of kuruma prawn ovary. Gene expression analysis, histological analysis, and functional analysis using recombinant protein suggested that a few arthropod hormone homologs may be involved in the regulation of reproductive process in the kuruma prawn.
