Figure 4From: UV-B induced transcript accumulation of DAHP synthase in suspension-cultured Catharanthus roseus cells Effect of EGTA and verapamil on UV-B-induced expression of CrDHS1. Six-day-old cultured cells was treated for 10 min with 0.2 or 2 mM of EGTA (A) or 0.5 or 5 μM of verapamil (B), followed by 5 min of UV-B irradiation. Other details are as in the legend to Fig. 2.Back to article page
