Effect of exogenous NO on PAs biosynthetic enzyme genes relative expression in the leaves of tomato under chilling stress. (A) LeADC relative expression, (B) LeADC1 relative expression, (C) LeODC relative expression, (D) LeSAMDC relative expression, (E) LeSPDS relative expression, and (F) LeSPMS relative expression. The treatment details are as in the Figure 5. Data represent the mean ± SE of three independent experiments and asterisks represent significant differences compared to control at P ≤ 0.05 according to Duncan’s multiple range test.
