For each gene, the Pearson correlation coefficient was calculated for all the 10 pairwise comparisons among the five accessions, as described in Materials and methods. Genes were then grouped into 11 groups (0-10) according to the number of comparisons having correlation coefficients less than 0.5 (group 10 corresponds to the genes with r < 0.5 from all 10 pairwise comparisons, whereas group 0 corresponds to genes with r ≥ 0.5 from all 10 pairwise comparisons). These results are given in the Observed column. Columns Per 1 to Per 10 show the numbers of genes from the 10 permuted datasets, as described in Materials and methods. These results are visualized in Figure 2.
