Abstract
Although accumulation of sequential analyses of cell number and size has revealed many aspects of mechanisms of leaf expansion, it was difficult to understand details of how leaf develops since cell proliferations and cell expansions occur simultaneously during leaf expansion. To overcome the difficulty, we developed a computer simulation of behavior of palisade tissue.
Fundamental information constituting the simulator is cell locations and volumes. We introduced cell expansion potential and cell proliferation potential depending on the location of the objective cell. Since pushing force of each cell can be presumed as the same, shape of a given cell was determined by arrangement of surrounding cells. Migration distance of the cell was determined by sum of expansion of cells, which located at basal part compared to the objected cell. In the presentation, we will introduce the simulation model and calculated results from several parameter sets.
