RT-qPCR analysis of Solyc01g007130.3 in the QTL region on chromosome 1 in response to C. fulvum inoculation. Both Ontario 792 and Moneymaker were inoculated with C. fulvum for 5, 9, 12, and 16 d. The blue and red bars represent Moneymaker and Ontario 792, respectively. The results were statistically analysed using Student’s t-test (*, P < 0.05; **, P < 0.01) and the asterisks indicate that the difference in gene expression in Ontario 792 and Moneymaker plants was highly significant
