| Congruent genetic structure in the lichen-forming fungus Lobaria pulmonaria and its green-algal photobiont. | The extent of codispersal of symbionts is one of the key factors shaping genetic structures of symbiotic organisms. Concordant patterns of genetic structure are expected in vertically transmitted symbioses, whereas horizontal transmission generally uncouples genetic structures unless the partners are coadapted. Here, we compare the genetic structures of mutualists, the lichen-forming fungus Lobaria pulmonaria and its primary green-algal photobiont Dictyochloropsis reticulata. We performed analys ... | 2011 | 22046957 |
