Figure 1: Time sequence of a simulation of the process of culmination. The cell types are Prespore (green), Prestalk O (red), Prestalk A (blue), Stalk (cyan), Pathfinder (magenta), Slime (yellow), and Stalk tube (grey).
Figure 2 (top row): Detailed view of the stalk elongation during the simulation of Fig. 1. The cell types are Prespore (green), Prestalk O (red), Stalk (cyan), Pathfinder (magenta), Slime (yellow), and Stalk tube (grey). Light bands indicate the regions of chemotactic motion towards cAMP.
Figure 2 (bottom row): Detailed view of the stalk elongation during the simulation of Fig. 1. Pressure differences are shown, indicated by the mean cell volume of individual cells, averaged over five samples at intervals of 2 sec. Volumes are indicated by a color gradient from dark red (small volume) to bright yellow (large volume).
Figure 3: Restoration of the direction of stalk elongation. Initially, the stalk tip is bent 90 degrees.
Figure 4a: Two culminants orienting away from each other due to NH3 production. The NH3 distribution is shown, indicated by a color gradient from dark red (low concentration) to bright yellow (high concentration), with blue bands of iso-concentration.
Figure 4b,c: Two culminants orienting away from each other due to NH3 production. The cell types are Prespore (green), Prestalk O (red), Prestalk A (blue), Stalk (cyan), Pathfinder (magenta), Slime (yellow), and Stalk tube (grey). Light bands indicate the cAMP waves.
