Fig. 6. Quantitative RT–PCR of four drought marker genes. (A) PtP5CS. (B) PtSUS3. (C) PtDREB8. (D) PtLPT3. Transcript levels are normalized to ACTIN and UBQ7, and error bars represent standard error (n = 3). Different letters indicate significant differences, and “n.s” indicates not significant (a lower-case letter for P. alba × P. davidiana and a capital letter for P. davidiana based on ANOVA with Tukey’s HSD, P < 0.05).
