The use of modified viral genes and host defense genes to obtain virus resistant plants


, : The use of modified viral genes and host defense genes to obtain virus resistant plants. Workshop on engineering plants against pests and pathogens, 1-13 January 1993, Madrid, Spain: 48-49

Current data on the molecular genetics of plant defence mechanisms known as systemic acquired resistance (SAR) and cross-protection and on their application to the development of virus resistant plants are summarized. SAR is the development of broad resistance to a wide variety of pathogens in the pathogen-free parts of a plant reacting hypersensitively to an attack. The hypersensitive response of tobacco Samsun NN to tobacco mosaic tobamovirus (TMV) infection was used as a model system.
