BRs biosynthesis capacity in WT and overexpressing lines (L2 and L8). (A) Transcriptional accumulations of the SoCYP85A1 gene in WT, L2 and L8 before and after 10-day drought stress. The expression level of L2 and L8 at time point 0 was defined as 1, respectively. (B) Detection of CS content. (C) Detection of BL content. CS, castasterone; BL, brassinolide; FW, fresh weight. The leaves from tobacco plants at 6-week-old stage were sampled for BRs analysis before and after 10-day water loss. Data are the means ± SD of three replicates and values with different letters are significant at P < 0.05.
