| Outline of Final Research Achievements |
Structure of the ventral lung is thought to be acquired in the common ancestor of actinopterygians and sarcopterygians, associated with pharyngeal pouch formation, and evolved as dorsal swimbladder in the actinopterygian lineages. Some animals of the lineages between gill-breathing teleosts and air-breathing tetrapods, have external gills during their larval period. The external gill development of Polypterus senegalus was examined experimentally, and found close related to the pharyngeal arch pattering. Thus, molecular mechanism of the external gill development was analyzed using RNA-seq.
