ML phylogenetic tree of the Pseudoalteromonas genus computed using a genome-scale set of genes. The light blue shaded area marks the strains assigned to the P. haloplanktis-like group; the strain names and nodes are colored according to the literature records (when available) about the pigmentation: strains with a red name are reported to be pigmented, where those with a blue name are non-pigmented. Support values for nodes, are reported when different from 100
