| Outline of Final Research Achievements |
The dinoflagellates include many harmful species causing red tide and shellfish poisoning. Some species in the dinoflagellate produce cysts in the life cycle. The existence of the cyst affects to the distribution expansion and colonization in new waters. However, the molecular biological induction and control mechanism of the cyst germination is still unknown. In this study, to clarify the control mechanism of induction of dormancy and germination in molecular biology, the expression gene from the cysts of harmful dinoflagellate Gymnodinium catenatum was analyzed. As the result, several expression gene sequences of functional proteins such as light-harvesting proteins, chlorophyll a-b binding protein, and ABC transporter ATP-binding subunit were obtained from the dormant cyst. This result suggests that preparation of the cyst germination advanced always from the dormant period.
