Leaf-nodulated plants are colonized by vertically inherited bacterial endosymbionts, which maintain symbioses throughout host generations. The permanent character of the interaction implies phylogenetic congruence between the host and the endosymbiont. However, the present population genetic study of Psychotria leptophylla provides evidence for a mixed symbiont transmission involving both vertical inheritance and horizontal transfers from the environment.
