Induction of Ca2+ signals in response to mannitol. A Time course of changes in [Ca2+]cyt induced by 250 mM mannitol in leaf tissue of barley and Arabidopsis. The dashed lines represent the time point of injection of the treatment. B Maximal increases in Δ[Ca2+]cyt in leaf and root tissue induced by different concentrations of mannitol. C Time courses of changes in [Ca2+]cyt induced by 250 mM mannitol in root tissues . The dashed lines represent the time point of injection of the treatment. D Time to reach the maximal increase of [Ca2+]cyt after injection of 250 mM mannitol in seconds (s). Values represent means ± SE of three independent replicates
