Motifs marked in bold are subsequences of ABRE considered in Table 1. Underlined motifs exhibit tissue specificity (GC vs LF) based on our analysis (Additional file 3). For convenient comparison of GC and LF, P-values falling beyond the thresholds (see Methods) are also listed. aMotifs appearing in more than 15000 loci are not listed.
