Relative expression of Fusarium verticillioides FUM1 and FUM13 genes in kernels of B73 inbred line inoculated with F. verticillioides (A,B) and F. verticillioides + A. flavus (C,D) at 6, 9 and 15 days post inoculation (dpi) under three different temperatures (20, 25 and 30 °C). Standard deviations (SD) of the mean are indicated by vertical bars (n = 3). The same letters over the line graphs state not significant differences among means of the three temperatures within each dpi (Latin letters) and the three dpi within each temperature (Greek letters), as resulting from Tukey’s honestly significant difference test (p ≤ 0.05).
