Intersection of differentially regulated gene lists identified by cross-species and species-specific hybridizations. Intersections performed between differentially regulated gene lists, identified by cross-species (PT) or species-specific (PP) hybridizations. Differentially regulated genes were identified between nematode infected and non-infected potato plants (based on infected:non-infected ratios). Intersections were performed for each time-point of the experiment (i.e. 5 or 10 d) and for each tendency of regulation (i.e. up or down). The PP and PT data corresponded to the sub SEM data filtered to include potato-tomato matched probe pairs with homology of bit-scores ≤ 129 (or E-values ≥ e-26). The intersection area presents the number of potato-tomato clone pairs that were differentially regulated for both PT and PP data. The first letter indicates the RNA source ('P' for potato plants); the second letter indicates the microarray chip platform ('P' or 'T' for TIGR potato or CGEP tomato microarray chip, respectively). (A) Down-regulated genes at 5 d; (B) up-regulated genes at 5 d; (C) down-regulated genes at 10 d; (D) up-regulated genes at 10 d.
