Interactions mediated by a public good transiently increase cooperativity in growing Pseudomonas putida metapopulations
Interactions mediated by a public good transiently increase cooperativity in growing Pseudomonas putida metapopulations
Bacterial communities have rich social lives. A well-established interaction involves the exchange of a public good in Pseudomonas populations, where the iron-scavenging compound pyoverdine, synthesized by some cells, is shared with the rest. Pyoverdine thus mediates interactions between producers and non-producers and can constitute a public good. This interaction is …
