| Outline of Final Research Achievements |
In this study, we focused on two streptophyte algae, Spirogyra parvula (filamentous) and the Closterium peracerosum-strigosum-littorale complex (unicellular) to reveal the factors for the land plant evolution. For this purpose, we tried to obtain whole genome sequences of these organisms and establish techniques for reverse genetics on Spirogyra parvula. We also tried to discover genes encoding a transcription factor acting for maintaining the multicellular body and differentiation of specific functions.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、アオミドロでは逆遺伝学的手法の確立には至らなかったが、ホシミドロ目の糸状性種と単細胞種に注目し、両者のゲノム解読および転写因子遺伝子同定を行ったことは、植物進化研究という学術的意義のみならず、植物がどのように進化してきたかを社会に伝えるための第一歩としても非常に高い意義がある。
