Construction of the PVX∷Ecp2 derivative and identification of lines responding with HR upon exposure to the ECP2 protein. (A) Schematic map of the PVX∷Ecp2 derivative. (B) Specific HR upon ECP2 presentation. Four-week-old plants of the collection of tomato lines and the control cultivar Moneymaker (lacking any known C. fulvum resistance gene) were inoculated with sap containing PVX∷Ecp2 (16) and symptoms were recorded 10–14 days after inoculation. Control plants of each line were inoculated with sap containing wild-type PVX. All plants gave normal systemic mosaic symptoms upon inoculation with wild-type PVX. Four lines gave systemic chlorosis and necrosis upon inoculation with PVX∷Ecp2. The symptoms on one of these plants, line 1, are shown. Normal mosaic symptoms developed after inoculation with PVX∷Ecp2 on all other plants.
