[edit]DescriptionPersistent-Symmetry-Frustration-in-Pollen-Tubes-pone.0048087.s001.ogv |
English: Simulation of expansive growth in the apical region of the pollen tube assuming cylindrical symmetry at transition zone ‘a’. In the simulation, we assume that growth is proportional to the radial part of the strain tensor (color bar). The wall is stretched in radial direction proportional to causing a local thinning which in turn results in expansion in z direction. Prior to the subsequent application of pressure, wall thinning is assumed to be compensated for by delivery of new cell wall material. 20 growth cycles are presented. |
