From: Dispersion of the Cf-4 disease resistance gene in Lycopersicon germplasm
Southern analysis of tomato genotypes with the 5′ fragment of Cf-9. Names of tomato genotypes are above the lanes and their numbers are as described in Table 1 and Materials and methods. The location of the Cf-4 and Hcr9-4E genes are indicated by arrows. Hybridizing bands in lines harbouring a functional Cf-4 gene that deviate from the pattern of the line Moneymaker-Cf4 are indicated by *. The lines Moneymaker, V541 (CN0697) and L. minutum (CGN15815) can be regarded as control lines, as they do not exhibit necrosis upon infection with PVX::Avr4.
