- Structural gene features have been assigned by querying the FLAGdb++ database [59]. For median length data, we performed two one-sided Wilcoxon tests allowing the identification of enrichment in wide (bold) or in compact gene structures (underlined) in a set of genes compared with all the other genes, i.e. genes within the whole gene set minus genes within the considered gene set. For intron-less gene percentages, we performed two one-sided Fisher exact tests allowing the identification of higher (bold) or lower (underlined) percentages in a gene set in comparison with all the other genes. NS indicates a non-significant difference. P-values in parenthesis are less than 5% with the Bonferroni correction. Both the first intron and 3'UTR lengths are never biased (data not shown).
