Table 7 Number of genes in each step of the significance analysis. Differential expression is defined with respect to a threshold |logFC| = 2. Significance analysis proceeds first by significance (i.e, p-value) with respect to control, followed by p-value in each possible pairwise contrast between the different stages. Exclusive DE genes refer to genes differentially expressed in only one of the four stages (corresponding to the bit strings '1000', '0100', '0010' and '0001')
