48—Siderophore transp element

Siobhán O'Brien of the University of Liverpool and colleagues published a paper showing how transposable prophages lead to P. aeruginosa adaptation. They alter iron availability to show that transposable prophages cause P. aeruginosa to evolve toward extreme siderophore production phenotypes. Their work suggests that prophages can mediate evolutionary divergence of social strategies, which wasn't clear before.
