Apoplastic polyamines increased in OsSAMDC-OX plants. a–c Apoplastic PUT, SPD, and SPM levels in OsSAMDC-OX leaves. Conidial suspensions (1 × 105 conidia/mL in 0.02% Tween-20) were sprayed onto the leaf surface of 2-week-old seedlings, and then apoplastic PA levels were determined at 3 and 6 dpi. Values are means ± SD (n = 3). Different letters indicate the significant differences based on one-way ANOVA with Tukey’s HSD test. d–f Apoplastic PUT, SPD, and SPM levels in OsSAMDC-RNAi plants. Others are same as mentioned above
