Fig. 5. Hydroxyl radical effects on Arabidopsis root fluxes. (A) Mean (±s.e.m.) time course of K⁺ release from Columbia roots. (B) Root cell OH^•-induced [Ca²⁺]_cyt increase measured using cytosol-targeted aequorin. Data were obtained with 1 and 10 mM ambient Ca²⁺; 1 mM Cu/a was added as indicated by the arrow. (C) Effect of 30 minutes exposure to test compounds on OH^•-induced [Ca²⁺]_cyt increase. Concentrations in mM.
