Relative quantification of genes encoding IAA9 and PR1 in Citrus plants infected with X. fastidiosa by RT-qPCR. cDNA samples were prepared using RNA extracted from a mixture of leaves and petioles of Ponkan mandarin and Pera sweet orange at 1, 7, 14, and 21 days after inoculation (d.a.i.) of X. fastidiosa or mock inoculated (control). The experiment was conducted with three biological replicates. The bars indicate the standard deviations of the means. (*) indicates significant difference (P ≥ 0.05) between the mean values obtained for each gene compared to control.
