Figure 5From: UV-B induced transcript accumulation of DAHP synthase in suspension-cultured Catharanthus roseus cells Effect of protein kinase inhibitors on UV-B-induced expression of CrDHS1. Six-day-old cultured cells were treated for 10 min with 10 or 100 nM staurosporine (A), 70 nM SB203580 (P38 inhibitor) (B), 40 nM SB600125 (JNK inhibitor) (B) or 5 μM PD98059 (ERKK inhibitor) (C), followed by 5 min of UV-B irradiation. Other details are as in the legend to Fig. 2.Back to article page
