The relative expression of genes involved in the water stress response, TdSHN1 (A) and TdDRF1 (B), in the roots of two durum wheat cultivars grown under control well-watered (CW), control stressed (CS), mycorrhized watered (MW), and mycorrhized stressed (MS) conditions. Etrusco is represented by white bars and Svevo by black bars. Data are presented as the mean ± SE (n = 5) and significant differences between the Etrusco and Svevo plants (within conditions) are indicated as follows: * p < 0.05. Different letters indicate significant differences between conditions within a genotype (uppercase letters for Etrusco and lowercase letters for Svevo) (Tukey’s test, p < 0.05). The two-way ANOVA results are reported in Table S2.
