Fold change in mean mineral concentration in maize seed samples transformed with the soybean ferritin transgene. The samples were screened with PCR to categorize them into those positive and negative for the soybean ferritin transgene. Three transformation events (P344-2-4-1, P344-4-1-6, and P344-5-2-1) were used for this test. The event effect was not significant (data not shown), therefore, the results presented are from combined data. The horizontal line represents normalized values for the transgene PCR negative samples. Significant differences (P < 0.05) are indicated with a star on top of each error bar for which the PCR positive and negative samples differ.
