| Outline of Final Research Achievements |
The sensitive plant Mimosa pudica folds its leaves in around a second when being touched. It remains largely unknown what mechanisms allow this plant to move so rapidly. To investigate the mechanisms, we conducted a whole-cell 3D imaging of a motor organ and analyzed how individual cells change their volume and shape during the movement. We also conducted a functional analysis of 15 candidate genes possibly responsible for the movement, by producing mutant plants that lack the normal function of each candidate gene. These experiments revealed that two of them actually play essential roles in the movement.
