Reconstruction of cytoplasmic flow in Chara with MPS simulation. (A) Schematic representation of the simulation. We moved the wall particles surrounding the cytoplasm in two directions (right box, red and blue regions). The left circle shows the cross-sectional velocity distribution of the resultant cytoplasmic flow in the simulation. The color denotes Vx/Vmax, where Vx is the velocity component in the direction of the x-axis, and Vmax is the maximum velocity Vmax. (B) Our MPS simulation (magenta) agreed closely with the flow velocity distribution derived from hydrodynamic simulation of Chara streaming in Goldstein et al. (green) for the region enclosed by a rectangle in (A, left). The horizontal axis shows y/R, where R is the radius of the cell. The vertical axis shows Vx/Vmax.
