Transcript amounts ofZmNAC41andZmNAC100during leaf development and in response to abiotic stress treatments. Relative quantities of ZmNAC41 (black bars) and ZmNAC100 (grey bars) were analyzed at different stages of the leaf development (A) and in leaves upon drought or high salinity conditions (B), as indicated below the graphs. Relative transcript amounts were determined by qRT-PCR and are expressed relative to ZmHMG on linear scale as means ± SE (n = 4). Asterisks indicate significant differences (P-value < 0.05) of the seedlings to the mature and senescent leaves (A) or stress-treated leaves to the respective mock-treated control (B).
