Lesson plan
Lar1
LAR1 ('Lichen-Associated Rhizobiales 1') refers to a specific bacterial lineage in the order Hyphomicrobiales (formerly Rhizobiales) that has most frequently been found directly in association with lichens. This lineage is currently known to associate with lichens that have a green-algal photosynthetic partner (as opposed to a cyanobacterial partner) and a fungal partner in the Lecanoromycetes (though other groups of fungi have not yet been examined). This lineage has been documented in association with all green-algal lichens specifically tested (all from North America), and was also found in a sequence library derived from Antarctic lichens. The specific ecological niche occupied by this lineage indicates that it may rely on certain nutrients that are abundant in green-algal lichen thalli but are rarer in other environments.
