Do externally applied electric fields influence the pattern formation in a developing cell?

We consider the problem of nonthermal interaction of a low frequency, low amplitude zero-mean electric field with a cell with nonlinear membrane. If the external electric field is spatially uniform the pattern of the rectified current densities looks like the one observed experimentally in the seaweed Fucus as an occasional 'birth defect' where two roots germinate. If the external electric field is spatially nonuniform the pattern of the rectified current densities looks like the one observed experimentally in a normally developing egg. This result points out the importance of a good characterization of the applied fields in biological experiments and in clinical therapy.
