| Abstract Detail
Botany 2021 and ASPB Special Symposium Scharnagl, Klara [1]. Symbiotic forms and the lichenized phenotype. Lichens have long been viewed as the poster children of a mutualistic symbiotic association, mainly between a filamentous fungal partner and a photosynthetic partner, algae or cyanobacteria. Yet, the more we peer into the world of lichens, the more complex they become. Here I will review the knowns and unknowns of the lichen symbiosis. For instance, how easily can we distinguish a lichen from a borderline lichen from a fungal-algal symbiosis? How many partners are actually involved in the lichen symbiosis? Do lichens follow the same ecological and evolutionary patterns as other organisms and symbioses, or are they an exception to the rule? In the second half of the talk, I will explore the approach of pulling lichens apart and putting them back together that we have used in our attempt to understand the mechanisms of the lichen symbiosis. I will examine how this approach has both informed and hindered our understanding of symbiosis and the lichenized phenotype.
