Cyanobacterial Photobionts of Tropical Cyanolichens

Caption: Cyanobacterial photobionts of tropical cyanolichens of the genera Acantholichen, Coccocarpia, Dictyonema, and Stereocaulon, belong to a previously unrecognized, exclusively lichenized, novel lineage with the name Rhizonema. These photobionts are shared between unrelated lichen mycobionts co-occurring in the same habitats, leading to improved strains by means of mycobiont and environmental selection, in a similar way as farmers domesticate and improve crops.
