Transgenic potato plants were created that express the N-terminal domain of the glycoprotein S (N-gS) from Transmissible gastroenteritis coronavirus (TGEV), containing the major antigenic sites of the protein. Extracts from potato tubers expressing N-gS were inoculated intraperitoneally to mice, and the vaccinated mice developed serum IgG specific for TGEV. Furthermore, when potato tubers expressing N-gS were fed directly to mice, they developed serum antibodies specific for gS protein, demonstrating the oral immunogenicity of the plant derived spike protein from TGEV.engOral immunogenicity of the plant derived spike protein from swine-transmissible gastroenteritis coronavirusjournal article1432-8798https://doi.org/10.1007/s007050070087open access581.15577.112Gastroenteritis coronavirusSpikeproteinBotánica (Biología)Genética2417 Biología Vegetal (Botánica)2409.92 Genética Molecular de Plantas
