Heatmap schema of quorum sensing regulator dissemination in selected Pseudoalteromonas genomes. The left panel of the heatmap is the evolutionary tree. The middle of the heatmap denotes the distribution of QS regulatory protein families in thirteen Pseudoalteromonas isolates. The top of the heatmap corresponds to the protein family IDs. Red: positive regulation; blue: both positive and negative regulation; green: negative regulation; yellow: unknown regulation direction. The color intensity represents the relative amount of the nucleotide base numbers of the genes containing cognate protein family (heavy: more similarity; moderate: intermediate similarity; light: less similarity). A range of BLAST hits were found to be classified into the same protein family. Notably, identified conserved and diverse genes are labeled with matching signatures; white: no hits; oblique stripes: relatively conservative; horizontal stripes: absolutely specific; others: absolutely conservative.
