Fig. 2. Western blot analysis of 30 mg protein extract from transgenic seeds containing the pfe-gene (F1–F7) and the phy-gene (P1–P4) and a untransformed control (wild-type, WT). French bean protein extract (FB) and the purified fungal phytase (+) were used as positive controls. Both the ferritin (pfe[upper panel]) and the phytase (phyA [lower panel]) genes are placed under the control of the glutelin promoter (Gt1 pr.). [42 (Reproduced with permission.)]
