| Outline of Final Research Achievements |
Investigating the mechanism about gene expression and development is an important issue for understanding plant life. Laboratory and field studies of an allotetraploid species Cardamine flexuosa revealed that genes related to cell wall biosynthesis and so on were found to be expressed diferrentially from homeologues.
To understand the evolutionary mechanism about gas-exchanging pore-formation, genes related to pore formation in Marchantia polymorpha and Arabidopsis thaliana were surveyed. It was found that genes in the same group function in pore formation in both species, suggesting an interesting similarity between analogous organs.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、植物が変動する環境に適応して生育する際に、どのようなメカニズムが働いているか、その一端を明らかにするものである。気孔は植物のガス交換を担う器官であり、二酸化炭素の取り込みや酸素の排出に重要な役割を果たす。通気孔が進化的にどのように発生してきたのか、気孔の密度がどのように制御されているかを明らかにすることは、温暖化など急激に変化する地球環境において植物の生育や地球環境維持において重要な知見をもたらすと考えている。
