Pig edema disease is a bacterial disease caused by Shiga toxin 2e-producing Escherichia coli belonging mainly to serotypes O138, O139, and O141. The B subunit of Shiga toxin 2e (Stx2eB) is a candidate protein for use in a vaccine against edema disease. We produced this protein in transgenic lettuce (Lactuca sativa), an edible plant that can be cultivated in a factory setting. In a transient expression system, we found that NtADH 5'-untranslated region (5'-UTR) functions as a translational enhancer in lettuce cells, and that Stx2eB accumulates most efficiently in the endoplasmic reticulum (ER) of lettuce cells. Stx2eB was produced in stable transgenic lettuce plants expressing a modified Stx2eB gene fused with the NtADH 5'-UTR and sequence encoding ER localization signals.
