Simulation results for early network growth using different diffusion and drift coefficient values.

<p><b>A–D.</b> Diffusion coefficient α varying from 0.1–1000, drift coefficient β is constant at 10. <b>E–H.</b> Drift coefficient β ranging from 0.01–100 when diffusion coefficient α stays constant 10. The remaining parameters are as per <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0054316#pone-0054316-t001" target="_blank"><b>Table </b><b>1</b></a>. <b>I</b>. A phase contrast image of <i>S. coelicolor</i> early hyphal growth for comparison. The dashed box shows the simulation results for α and β values used in further simulations.
