| Research Abstract |
This study was purposed to establish the methods for investigation of gene functions in the chordate Ciona intestinalis. It was shown that enhancer detection is an effective way to create insertional mutants. It was shown that Hox1 functions in the patterning of epidermis. As a reverse genetic approach, a novel method of targeted disruption of maternally expressed genes was established. Transgenic maker lines were established that express reporter genes in the tissue-specific manner. The neural tissue-specific lines were utilized to investigate how the larval central nervous system was remodeled to construct the adult nervous system during metamorphosis. A method to live-image the cell cycle progression was introduced, and by using this method mechanisms of the coordination between cell division and morphogenesis were shown. A new method of germline transformation in Ciona mediated by Sleeping Beauty transposon was established.
