Modeling of growth in shoot apical dome

Z. Hejnowicz, J. Nakielski

Abstract


The vectorial field of displacement velocities V in growing apical dome is calculated from the scalar field adjusted to the geometry of the dome and to different variants of the distribution of linear growth rate along axis. The distribution of growth rate in volume and the temporal course of cell wall net deformation in the apical dome calculated from the V fit within the range of empirical data when the linear growth rate along the axis increases with distance from the tip. The distribution of volume growth rate attains the minimum inside the distal region of the dome where the zone of central mother cells occurs.
