Fig 6. Three simulations showing HetR profiles in filaments of wild type, ΔpatA, and ΔpatA with no inhibitor leakage from the terminal cells (d_broder = 0).

HetR concentration is represented by the brightness of green and the heterocysts present an additional white cell wall. For the wild type one can observe cells with high levels of HetR, candidates to differentiate into heterocysts, between existing heterocysts.
