The characteristics of [Ca2+]i response to Glu in rice roots. a Pseudocolor images of aequorin luminescence in roots treated with different concentrations of Glu. The relationship between luminescence intensity and the pseudocolor images are scaled by a pseudocolor bar and the numbers next to the pseudocolor bar are maximum and minimum values of luminescence intensity. b Concentration dependence of [Ca2+]i increase in rice roots. Data were fitted by the Michaelis-Menten function. c The time courses of [Ca2+]i changes induced by different concentrations of Glu in rice roots. The results were obtained from at least three independent experiments (mean ± sd; n = 10)
