Expression of two candidate TDFs in germinating cysts of different P. infestans strains. RT-PCR of TDF3.4 and TDF3.1 on the two parental strains of the mapping population, 80029 (P1) and 88133 (P2), and nine F1 progenies. The sizes of the amplification products (bp) are on the right. A stands for avirulent and refers to strains with AVR3b–AVR10–AVR11 phenotype, whereas V stands for virulence for strains with the avr3b–avr10–avr11 phenotype.
