Bioluminescence response of the Arabidopsis aequorin mutant ( Col0-1 Aeq Cy+ ) to a combined MF (B
= 65 μT) and EMF ( f = 50 Hz, B
= 5 μT), matching Ca2+-ICR conditions (a-c). The horizontal bars below the graphs indicate the time of Ca2+ – ICR condition. All data are normalized against the dark current signal, which also corresponds to control experiments with wild-type plants (labelled as WT). The vertical bars on the curves mark the standard deviation at the indicated positions.
