Figure S1: GC-content of Proteobacteria with or without inferred Chi sites. A comparison of GC-content between species of Proteobacteria with inferred Chi sites and without inferred Chi sites. The GC-content of the candidate Chi motifs is indicated in the third boxplot. B comparison of GC-content between species of Gammaproteobacteria with inferred Chi sites and without inferred Chi sites. (***) P<10^-5, Wilcoxon test.

Table S1. Statistical overrepresentation of Chi motifs across Markov models.

Table S2. Number of species identified with Chi motifs across Markov models (25 motifs searched).

Table S3. Number of species identified with Chi motifs 25 motifs searched).

Table S4. Number of species identified with Chi motifs across Markov models (830 motifs searched).

Table S5. Number of species identified with Chi motifs (830 motifs searched).

Dataset S1. List of analyzed genomes and genomic features.

Dataset S2. Phylogenetic tree of Proteobacteria in Newick format.

Dataset S3. List of species with candidate Chi motifs (25 polarized motifs searched).

Dataset S4. List of species with candidate Chi motifs (25 non-polarized motifs searched).

Dataset S5. List of species with candidate Chi motifs (830 non-polarized motifs searched).

Dataset S6: List of all statistically overrepresented motifs in Proteobacteria. Columns 2 to 7 indicate the number of species of Proteobacteria where the motif has been identified across Markov models using the criteria defined in Table S1. Column "avg" indicates the average number of species where the motif was identified across Markov models. Column "score" indicates the number of nucleotides shared with the Chi motif of E. coli.
