Figure 3.

The relative expression of genes involved in mycorrhizal colonization, Fm18S (A) and TdPT11 (B), in the colonized roots of two durum wheat cultivars grown under 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). An absence of letters means that there were no significant differences between conditions. The two-way ANOVA results are reported in Table S3.
