Analysis of biological variability in microarray samples. a–b Principal component analysis (PCA) of cotyledon samples at 3 and 5 days post inoculation (dpi) (A), and directly inoculated leaf at 5 dpi (B), for the Tendral and Planters Jumbo cultivars analyzed after normalization of microarray data. c–d Dendrogram obtained after clustering cotyledon and directly-inoculated leaf samples. Bootstrap values are shown in the boxes. The first two axes of the PCA accounted for 69.43 % (PC-1 = 49.27 % and PC-2 = 20.16 %) of the variability in the data in A and for 68.03 % (PC-1 = 39.82 % and PC-2 = 28.21 %) in B
