The inhibitor‐of‐virus replication ( IVR ) gene associated with the local lesion response to Tobacco mosaic virus in tobacco codes for a putative protein with a molecular mass of 22 kDa . Earlier work revealed that when tomato ( Solanum lycopersicum ) cv. VF36 plants are transformed with a cDNA clone encoding this gene, they become partially resistant to Botrytis cinerea infection. The transformation of tomatoes with the IVR gene induced partial resistance to in vitro seedling infection by Alternaria alternata , Pythium aphanidermatum and Rhizoctonia solani and faster seedling growth. Resistance to damping‐off was observed in transgenic seedlings planted in soil infested with R. solani and P. aphanidermatum . Early blight ( Alternaria solani ) and powdery mildew ( Oidium neolycopersici ) were also partially controlled in mature transgenic tomato plants.
