Sure, from my understanding, the underlying mechanism is the Hodgkin-Huxley model (https://en.wikipedia.org/wiki/Hodgkin%E2%80%93Huxley_model) that describes the generation of action potentials from changing electric field concentrations with respect to the outside of the cell wall.
Yes, plants are sensitive and responsive to EM fields in that range. I wrote a book on this topic a few years ago. Plants respond to static and dynamic electric fields across a huge range of voltages and frequencies. There is quite a bit of literature available, but you need to search around...
