Distribution of TF orthologous groups in studied genomes. (A) Distribution of TF orthologous groups in genomes. Conserved TFs are present in more than half analyzed genomes within the lineage. Universal TFs are present in all genomes of the lineage. (B) Examples of functional annotations for conserved TFs. TFs for which regulons were reconstructed are shown in bold, other TFs are underlined. TFs universally conserved in at least one lineage of the Lactobacillales are highlighted in green.
