Effects of the inhibitors for protein kinase and phosphatase against β-ocimene induced [Ca2+]c transient. The inhibition rates against the peak amplitudes of luminescence in response to fumigation with β-ocimene are shown. Staurosporine (Sta; 10 µM), K252a (10 µM) and Calyculine A (CA; 1 µM) were extracellularly applied to Arabidopsis leaves for 2–3 hrs prior to the fumigation. Data represent means ± SEs (n = 3–4). # and *p < 0.05, the two-tailed Student's t test.
