Fig. 1

Graphical representation of the occurrence of 316 MLO cis-acting regulatory elements (CREs). The CRE dataset refers to the putative promoter region (PPR) of 414 MLO homologs occurring in 25 plant or algae species. The colour of heat map cells refer to the normalized Z-score, related to the standard deviation from the mean number of times a CRE occurs across species. Clustering on the right of the figure refers to species clustering according to the CRE profile, whereas clustering on the top of the figure refers to individual CREs. Red points indicate monophyletic-species groups. Information on the name and the functional category of individual CREs in provided at the bottom of the figure
