Psychrobacters are descendants of pathobionts: now in mSystems

Welter et al.’s analysis of the evolutionary history of Psychrobacter is out in mSystems. Her phylogenomic analysis, combined with the outcome of >10,000 growth tests, indicates that the psychrophiles in this genus are descendants of warm host-associated ancestors. More about this topic, featuring Welter’s analysis, in the blog Small Things Considered.
