[TMV-infection localization and development of induced virus resistance in Nicotiana sanderae Hort., Datura stramonium L. and Datura metel].

The localization of virus infection and development of local and systemic induced resistance in plants Nicotiana sanderae Hort., Datura stramonium L. and D. metel L. infected by TMV have been studied. It was shown that acquired resistance to the second infection is induced in hypersensitive plants infected by TMV independent of localization mechanism. No definite correlation exists between these defense reactions.
