Induction of Ca2+ signals in response to H2O2. Maximal increases in Δ[Ca2+]cyt in barley and Arabidopsis leaf (A) and root (B) tissue induced by different concentrations of H2O2. Time courses of changes in [Ca2+]cyt induced by 10 mM H2O2 in leaf (C) and root (D) tissues. The dashed lines represent the time point of injection of the treatment. (E) Time to reach the maximal increase of [Ca2+]cyt after injection of 10 mM H2O2 in seconds (s). Values represent means ± SE of three independent replicates
