Supplementary Figure 13: Elemental and Compton scattering maps of VIT1 and IRT1 + FER1 transgenic cassava stems and petioles.

a) Elemental and Compton scattering maps obtained from a single scan (run 14761) of a series of transgenic, empty vector control (EV) and non-transgenic control cassava stems and petioles. Scan area was 96 mm × 15 mm with 0.02 mm pitch, and obtained with a collection time of 0.005 seconds/pixel for a total scan time of approximately 5 h. b) Elemental and Compton scattering maps obtained from a single scan (run 14762) of a series of transgenic, empty vector (EV) and wild type cassava storage roots. Scan area was 118 mm × 13 mm with 0.02 mm pitch, and obtained with a collection time of 0.006 seconds/pixel for a total scan time of approximately 7 h. The maximum intensity of each image has been scaled independently.
