Induction of ZmNAC41 and ZmNAC100 in response to hormone and hormone analog treatments. Relative quantities of ZmNAC41 (A) and ZmNAC100 (B) transcripts in mock-treated control leaves (black bars) and after 0 h (left bracket), 10 h (middle bracket) and 24 h (right bracket) of treatment with 1 mM JA (diagonal hatched bars) or 1.3 mM INA (vertical hatched bars) and after 0 h and 10 h of treatment with 5 mM ACC (cross-hatched bars) were analyzed by qRT-PCR and are expressed relative to ZmHMG on linear scale as means ± SE (n = 4). Dissimilar letters indicate significant differences (P-value < 0.05) between the treatments.
