Microtubule-based nucleation results in a large sensitivity to cell geometry of the plant cortical array
Fig 7
Clear signs of local domain formation with isotropic nucleation on large (80x80 μm2 periodic) simulation domains.
Scatter plots of density as a function of S2, coloured by G for the three nucleation modes (rows: LDD, GDD, ISO) and three domain sizes (columns: 20 × 20, 40 × 40 and 80 × 80 μm2) as indicated in the graphs. Most points fall on a curve from low density and low S2 to high density and high S2 with increasing G. Points with relatively high G and density, but distinctly lower S2 than other points with similar G and density are in the regime of spontaneous alignment, but the occurrence of multiple aligned domains with different orientations reduces the global S2. The most cases, and most severe ones, occurred with isotropic nucleation on the largest domains. These plots are based on the same data as S4 Fig, with 100 simulations per (target) G value. Simulation time: s (8 h, 20 min; lower for the highest G values for LDD and GDD, because not all simulations terminated in time).
