ZEA in Non-Trangenic and Trangenic Maize In the meta-analysis, a highly significant difference ( p < 0.001) was observed in the amount of ZEA between non-transgenic ( n = 42) and transgenic ( n = 42) maize in 2 out of 28 experiments (7%) [ 46 ], with mean values ranging between 0.02 and 0.4 mg/kg ( Figures S13 and S14 ).
