Expression pattern of DELLA3, MCA2, PE and PLC genes in pea roots treated with 10−5 M CO5 for 24 h. As a control, medium-treated plants were used. The expression was normalized against the constitutively expressed ubiquitin and actin genes. For each gene, the transcript level in non-inoculated roots of wild-type or mutants was set to 1 (control), and the level in treated roots was calculated relative to the control values. The graphs show the results of three independent experiments. The error bars represent standard errors of the mean (SEM) of three repeats. The asterisks indicate statistically significant differences based on one-way analysis of variance (one-way ANOVA), followed by Tukey’s post-hoc test results. (** p < 0.01, *** p < 0.001).
