It has been reported recently that genes encoding antigens of
bacterial and viral pathogens can be expressed in plants in a form in
which they retain native immunogenic properties. The structural protein
VP1 of foot-and-mouth disease virus (FMDV), which has
frequently been shown to contain critical epitopes, has been expressed
in different vectors and shown to induce virus-neutralizing antibodies
and protection in experimental and natural hosts. Here we report the
production of transformed plants (Arabidopsis thaliana) expressing VP1. Mice immunized with leaf plant extracts elicited specific antibody responses to synthetic peptides representing amino acid residues 135 to 160 of VP1, to VP1 itself, and to intact FMDV particles. Additionally, all of the immunized mice were protected against challenge with virulent FMDV. To our knowledge, this is the
first study showing protection against a viral disease by immunization
with an antigen expressed in a transgenic plant.
