title: Evolution and development: PINpointing the origins of auxin transport mechanisms.
abstract: Specialists and non-specialists alike know that auxin regulates plant development, but the role of auxin transport mechanisms in the context of land plant evolution has been controversial. Two recent studies resolve the controversy by demonstrating that PIN-mediated auxin transport regulates morphogenesis in a moss.
