Expression dynamics of selected BELL genes in inoculated Pisum sativum roots (cv. Frisson) at different stages of symbiosis development. mRNA levels were normalized against Ubiquitin and values were calculated as ratios relative to non-inoculated root expression levels (control). The data of three independent biological experiments were analyzed. For one biological experiment, three technical replicates were obtained at each developmental stage. Bars represent the mean ± SEM. Different letters indicate statistically significant differences between groups as analyzed by one-way analysis of variance (one-way ANOVA), followed by Tukey’s post hoc test.
