FIGURE 4.

Aflatoxin production in the transgenic and null kernels of two different events in 2016 and 2017. Aflatoxin production in T3 (2016) generation (A, C) and T4 (2017) generation (B, D) transgenic and null kernels without aflM under field natural infection (A, B) and after incubation under laboratory Kernel Screening Assay conditions without inoculation (C, D). Data are the mean and standard errors of 12–36 replicates of each event. Bars with different letters are significantly different at P ≤ 0.05. Transgene represents the kernels that contain aflM gene. Null represents the segregating non-transgenic kernels from the same event.
