Appendix 1—table 2.
Seven DNA motifs are significantly enriched in the 1kb upstream region of M4 module genes. The presence of the motif in sequences and p-values were obtained using the HOMER package. Motif sequences were annotated by searching the plant cis-regulatory sequence database in PlantPan2 (http://plantpan2.itps.ncku.edu.tw/).
