[Potent natural inhibitors of tobacco mosaic virus multiplication]. / Sur de puissants inhibiteurs naturels de multiplication du virus de la mosaique du tabac

The hypersensitivity reaction in Nicotiana tabacum var. Xanthi n.c. infected with Tobacco mosaic virus (T.M.V.) leads to the production of aromatic amides (ferulylputrescine, diferulylputrescine, p-coumarylputrescine and di-p-coumarylputrescine) inthe cells around the necroses. Similar compounds are formed in Xanthi plants after floral induction. p-coumarylputrescine, di-p-coumarylputrescine and caffeylputrescine strongly inhibit T.M.V. multiplication.
