Abstract.
We propose that the first stage of membrane fusion need not be the formation of a single stalk. Instead, we consider a scenario for defect-induced membrane fusion that proceeds cooperatively via multiple stalk formation. The defects (stalks or pores) attract each other via membrane-mediated capillary interactions that result in a condensation transition of the defects. The resulting dense phase of stalks corresponds to the so-called fusion intermediate.

Note that within the framework of the recent model of the stalk [10], the hemifusion is equivalent to the trans-monolayer contact (TMC).

This is similar to the case of membrane-induced interactions between inclusions (for a single bilayer membrane): N. Dan, P. Pincus, S.A. Safran, Langmuir 9, 2768 (1993); N. Dan, A. Berman, P. Pincus, S.A. Safran, J. Phys. II, 4, 1713 (1994).
Note, that we obtain the expression for the interaction free energy between two junctions which is different by a numerical factor from the corresponding one reported in reference [22].
