Electron-microscopic analysis of assembled VLPs from N. tabacum plants infected with TMV mutated at amino acid E50 (TMV-CP^E50Q, TMV-CP^E50K, TMV-CP^E50R, TMVCP^E50D, TMV-CP^E50M) or at amino acid D77 (TMV-CP^D77N, TMV-CP^D77K, TMV-CP^D77R, TMV-CP^D77E, TMV-CP^D77A) or w.t. (TMV-U1). The samples were negatively stained and analyzed at a magnification of 39,000. The bar represents 100 nm.
