Effect of protein kinase inhibitor and MAPK cascade specific inhibitors on UV-B-induced CDPK activity (a), MBPK activity (b), Tdc and Str gene expression (c) and accumulation of catharanthine (d) in cell suspension cultures of C. roseus. Six-day-old cell suspension cultures were pre-incubated with staurosporine (St), SB 203580 a P38 inhibitor (SB2), PD 98059, an ERKK inhibitor (PD) or SB 600125 a JNK inhibitor (SB6) at concentrations indicated followed by 5 min of UV-B irradiation. Other details are as in the legend to Figure 5.
