Network analysis of putative promoter sequences and novel motifs discovered in the putative promoter regions (PPRs) of upregulated MLO genes. a) Sequences similarity network of 414 MLOs based on MAFFT similarity matrix of 200-bp 5′ upstream from the translation start site. Circles (nodes) show the PPRs (red for upregulated MLOs; green for remaining homologs) and lines (edges) indicate the connections. The sequence identity cut-off, used to generate the network edges, is > 30%. b) Typical distribution of PPR AT-content MLO genes upregulated upon PM challenge. c) Sequence logo of two motifs (M1 and M2) identified in the PPRs of MLO upregulated upon PM challenge. M1: Thymine-rich motif; M2: TC box-like
