Photoautotrophic symbiont and geography are major factors affecting highly structured and diverse bacterial communities in the lichen microbiome
Summary Although common knowledge dictates that the lichen thallus is formed solely by a fungus (mycobiont) that develops a symbiotic relationship with an alga and/or cyanobacterium (photobiont), the non‐photoautotrophic bacteria found in lichen microbiomes are increasingly regarded as integral comp...

Major bacterial community trends are significantly correlated with differences in large‐scale geography, photobiont‐type and mycobiont‐type. The lichen as a microcosm represents a structured, unique microbial habitat with greater ecological complexity and bacterial diversity than previously appreciated and can serve as a model system for studying larger ecological and evolutionary principles.
