Ca²⁺ stores for the volatiles-promoted [Ca²⁺]_c transients in Arabidopsis leaves. Effects of 10 mM BAPTA (white bars), a Ca²⁺ chelator, and 0.5 mM ruthenium red (gray bars), a plasma membrane and endomembrane Ca²⁺-permeable channel inhibitor on the volatile-promoted [Ca²⁺]_c transients were tested. Inhibition rates against the peak amplitudes of luminescence in control experiments were shown. Black bars indicate the relative peak amplitudes of the luminescence in control experiments for each treatment. Data represent means ± SEs (n = 3–6). # and *p < 0.05, the two-tailed Student's t test.
