Promoter motif enrichment in the co-expression clusters of maturing AC Domain (A) seeds. Motif enrichments (P < 10e⁻³) are found in embryo (em) and endosperm (en) clusters corresponding to the same seed maturation phase or in tissue specific clusters; P value (1/log10) is shown by the color scale at the top. Enriched motifs and the respective P values can be found in Additional file 9: Table S3. Black, grey and striped bars represent clusters with peak expression at early (20 DAA), mid (30 and 40 DAA) and late (50 DAA) phases of seed maturation, respectively. The white bar represents gene clusters with constitutive/random expression patterns. Degenerate characters in the consensus sequence: K = G/T, S = C/G, R = G/A, Y = C/T
