Outline of Final Research Achievements |
In this study, we investigated the structural significance of the jigsaw puzzle-like morphogenesis of leaf epidermal cells, and explored the potential application of the cell biological structure to artificial structures. Our analysis indicated that the jigsaw puzzle-like cell shape moderates local growth throughout the organ, which may affect the formation of the round fan-shaped morphology of the cotyledons. Furthermore, we found that the cell wall waving pattern observed in pavement cells could be applied to the structure of joints. We also developed an experimental system to non-destructively reconstruct the three-dimensional morphology of above-ground parts such as flower stems and lateral branches of Arabidopsis thaliana, and to measure the angular and curvature distribution of lateral branches. Using this system, we analyzed temporal changes in lateral branch morphology of myosin XI mutants, suggesting that myosin X contributes to the upward growth of lateral branches.
