PIN1 mediates vertical transport of IAA from the shoot to the root along the embryonic apical–basal axis and creates an auxin sink that drives basipetal auxin transport upward from the root apex via PIN2 efflux carriers.

Bacterial viruses (bacteriophages) carry DNA from one bacterium to another.

It takes place between same or closely related species.
