Figure 5

The differential expression of cell wall related genes. Quantitative real-time PCR (RT-PCR) analysis of α-expansins (A-C), β-expansins (D, E, G), ZmXET1 (F) and ZmMHA (H) genes at different time points after treatment of six-day-old maize seedlings with 200 mM NaCl. Maize root samples were harvested after 0, 2, 4, 8, 16, 24, 48 and 96 h for RNA isolation. The y-axis shows relative expression values and the x-axis indicates the hours after treatment with NaCl. Expression values were normalized to those of the beta actin gene. The relative expression value of 0 h was assigned as 1. Each experiment was repeated three times and relative expression values are shown as the average values ± SD (the standard deviation). White bars, no treated seedlings; Black bars, seedlings treated with 200 mM NaCl.
