Morphology diagram showing the correspondence of the predicted structure of the self-assembled Golgi stacks with their biological phenotypes as a function of the model's key parameters. Parameter J_in is the export rate of transport intermediates from ERES regions; r_A is the retrograde loss rate of protein species A (e.g., representing SNAREs of the Golgi-ER interface); and r_B is the rate at which protein species B (e.g., cargo proteins that are modified in the Golgi) reaches its functional form. The tether rate determines the speed at which bonds form between VTCs and growing cisternae. See main text for details.
