| Outline of Final Research Achievements |
We analyzed morphogenetic process of Arabidopsis thaliana leaf epidermal cells with complex morphology, and visualized cell shape and cell connection mode at the tissue level. In particular, when cellulase (digesting cellulose in the cell wall), was treated on leaves of plants, the leaf epidermal cells change from a complicated intricate configuration like a jigsaw puzzle to a straight extension. We focused on microtubule-associated protein called RIC1, which was known to play an important role in the formation of jigsaw puzzle type of leaf cells, and analyzed the role of RIC1 in the cellulase response. As a result, we found that no significant change was observed in the cell shape of the jigsaw puzzle even when the cellulase was treated with the mutant lacking RIC1.
