Figure 6

Relative expression of TcPR-4b in TSH1188 and Catongo meristems inoculated or not (control) with M. perniciosa . A. Representation of the plant symptoms and fungus phase during the infection time course in Catongo genotype. The harvesting times of inoculated plants are indicated on the top of the figure. (*) indicates the times that were harvested also in the non-inoculated (control) plants. B. RT-qPCR of TcPR4b. The control, used as calibrator (for this reason is always 1), corresponds to the average of the expression values of TcPR-4b in 5 non-inoculated samples in each genotype (see also Methods section). The results are the arithmetical mean of the repetitions ± standard error. Different letters indicate significant statistical difference between samples by the Scott-Knott test (P ≤ 0.01): lower case letters correspond to statistics between harvesting times for each genotype while upper case letters correspond to statistics between genotypes for each harvesting time. dai: days after inoculation; hai: hours after inoculation.
