Plasmid Invasion Front: 2D Reaction-Diffusion Lawn
A 2D reaction-diffusion lattice model of conjugative plasmid spread across a bacterial lawn: donor, recipient and transconjugant densities react locally by the Levin-Stewart-Rice mass-action law and diffuse spatially, producing a traveling invasion front you can tune with conjugation rate, fitness cost and segregational loss.
This is a 2D-native counterpart to the 3D liquid-culture conjugation model: instead of individual cells drifting through a stirred volume, a lattice of patches holds local donor, recipient and transconjugant densities that react by the same Levin–Stewart–Rice mass-action law and diffuse across the lawn. Seed a donor patch at the center, tune conjugation rate, fitness cost and segregational loss, and watch a genuine traveling invasion wavefront spread the plasmid outward — or stall and recede — across the surface.
