Quantification of mRNA corresponding to on gene of each of the clusters I to VI. Relative mRNA levels were quantified by quantitative RT-PCR in biological replicates of samples used in Figure 1. A condition corresponding to A. thaliana roots 4 days after inoculation (4d), corresponding to necrotrophic stage of the interaction was added. Data are presented as expression ratios relative to UBC, WS21 and Mago Nashi reference genes (2^−ΔCT). Grey bars represent mean signal obtained following oligoarray hybridizations (black left axis). Red point and crosses represent relative expression values obtained for two independent biological replicates analyzed using qRT-PCR (red right axis).
