ABSTRACT
Recombinant secretory antibodies, stable in the harsh environment of the mucosal system, have also been expressed in plants for the purpose of passive immunization. Subunit vaccines expressed in transgenic plants have been assessed in clinical trials, and the results have been promising. Antibodies and other therapeutic agents such as interleukins are also being produced in plants. This chapter provides a cornucopia of examples of vaccine and other biopharmaceutical proteins produced in plants. Applications of this technology range from anticancer agents to contraceptives, and are discussed in detail here. The chapter ends with a description
of recent biotechnological efforts made to enhance the nutritional content and/or medicinal properties of plants.
