Figure 5.

Gene expression changes in stems of N. sylvestris transgenic lines. A, RNA was analyzed by real-time RT-PCR for expression of floral induction-associated (NFL2, MADS1, and MADS2) and GA-induced (GA2OX3 and GA2OX5) genes. The figure shows average relative mRNA levels ± se for four plants, except for S2 (three plants). Significant differences from the S8 line are denoted by asterisks, except for the transgene StNDB1. B, Significant correlations of MADS1 and MADS2 expression to NADPH/NADP⁺ ratio and d-Xyl are denoted as Pearson coefficients and P values over 15 individual plants. WT, Wild type.
