Figure 2. Pbz application modulates endogenous abscisic acid and spermidine contents.

Figure 2

Effects of PBZ application (0, 0.8 and 1.6 ppm) in irrigated (I) and deficit-irrigated (DI) tomato plants on the endogenous content of (A) abscisic acid (ABA) and expression of ABA biosynthesis genes (B,C) SlZEP, SlNCED and SlAAO1, and relative content of (D) spermidine (Spd) and expression of (E) spermidine synthase gene (SlSPDS) in the leaf tissue of 105-days old tomato plants. Letters (A,B and a,b,c) indicate significant differences (one way ANOVA, p < 0.05) from the control in irrigated and deficit-irrigated conditions, respectively.
