    "abstract": "A salient feature of stationary patterns in tip-growing cells is the key role\nplayed by the symports and antiports, membrane proteins that translocate two\nionic species at the same time. It is shown that these co-transporters\ndestabilize generically the membrane voltage if the two translocated ions\ndiffuse differently and carry a charge of opposite (same) sign for symports\n(antiports). Orders of magnitude obtained for the time and lengthscale are in\nagreement with experiments. A weakly nonlinear analysis characterizes the\nbifurcation.",
