| Outline of Final Research Achievements |
This study aims to reveal how the remarkable heterophylly exhibited when the aquatic plants submerged is controlled and how it evolved, using Callitriche palustris (Plantaginaceae) as a model. As a result of the study, it was confirmed that various phytohormones are involved in the heterophylly of this plant. Also, comprehensive and comparative expression analyses using the closely related plant which does not show heterophylly revealed the gene set important for heterophyllic leaf formation in C. palustris. Through this study, we were able to reveal a part of the mechanism of differential leaf development, which is a fundamental finding in understanding the evolution of heterohpylly in aquatic plants.
