Expression of miR168 precursors and structural features of the MIR168 promoter. (A) qRT-PCR analysis of pre-miR168a (left panel) and pre-miR168b (right panel) expression in response to elicitor treatment. The relative expression level in comparison to the corresponding non treated controls is given for each time point (elicitor vs control non treated plants). Error bars represent the mean ± SD of two biological replicates and three technical replicates for each biological replicate (*, P ≤ 0.05 ; **; ≤0.01). All values were normalized against Ubiquitin. (B) Structural features of the MIR168a promoter from Arabidopsis. The location of known cis-acting elements is shown (for details on cis-elements, see Additional file 1: Table S2).
