Flow of information in the root cell as a function of the logarithm of the angular frequency of ethylene oscillations. (a) In this panel, a window of maximum and minimum information value is shown, indicating that a set of ω values exists for which ERF 1 continuously transits between its on state and its off state, i.e. the CTR1 and EIN2 molecules are alternately activated. (b) δ I = I
