Outline of Final Research Achievements

The genome survey for Cryptistan organisms, Cryptomonas sp., which secondarily lost the photosynthetic ability was carried out. Also the light-respond functions in C. sp were surveyed. The genome size expansion was observed in of C. sp. with comparison a photosynthetic relative despite of the loss of ability. As well as retaining chlorophyll biosynthesis proteins in the plastid genome, the photosynthesis-related genes are partially retain in the nuclear genome. And we tried to identified a substance produced as respond to light conditions in C. sp. The main publication in the project is in preparation and the multiple papers partially relating to the project have been published.

Academic Significance and Societal Importance of the Research Achievements

葉緑体の機能は光合成だけではない。それはマラリア原虫や寄生性植物などが光合成を失っても非光合成葉緑体を維持していることからも明らかである。また、一見有利な形質に見える光合成が、生物にとって必ずしも良い面だけを面だけをもつとも言い切れない。本研究は従来あまり議論されてこなかった、非光合成の葉緑体に残存する従来“光合成以外の機能が想定されてこなかった”遺伝子機能に注目した。この点は独創的と言え、既知と思われている遺伝子の新たな機能探索は今後の生態学、光合成学及び育種などにも波及する可能性がある。
