Figure 6From: UV-B-induced signaling events leading to enhanced-production of catharanthine in Catharanthus roseuscell suspension culturesEffect of verapamil (Vera) and EGTA 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 verapamil or EGTA at concentrations indicated followed by 5 min of UV-B irradiation. Other details are as in the legend to Figure 5.Back to article page
