Differential expression of four genes in Foc strains serially passaged through different cucumber cultivars using quantitative reverse transcriptase PCR. (a) G‐protein α subunit encoding gene fga1. (b) Sucrose nonfermenting 1 gene snf1. (c) F‐box protein encoding gene frp1. (d) Class V chitin synthase gene chsV. Ra and Sa represent Foc strains re‐isolated from resistant and susceptible cultivars, respectively. Generation 0 represents the original strain foc‐3b. Values are means ± SD of three replicates
