Lichens symbioses, commonly described as fungal partnerships with a photosynthetic partner (green algae and/or cyanobacteria) are associated with a diverse bacterial community. Whereas the microbiome diversity and function of terrestrial lichens has been well studied, knowledge about the non-photosynthetic bacteria associated with marine lichens is still scarce. Since there is a clear vertical zonation of lichens across the littoral belt we hypothesized that this correlates with significant… 

The Bacterial Community of the Foliose Macro-lichen Peltigera frigida Is More than a Mere Extension of the Microbiota of the Subjacent Substrate.

The results reinforce the idea that lichens would carry some components of their microbiome when propagating, but they also could acquire part of their bacterial community from the substrates.

The Total and Active Bacterial Community of the Chlorolichen Cetraria islandica and Its Response to Long-Term Warming in Sub-Arctic Tundra

The results suggest that the bacterial community of the lichen C. islandica is dominated by acidophilic taxa and harbors disproportionally active rare taxa, and it is shown for the first time that climate warming can lead to shifts in lichen-associated bacterial community composition.

The Lichens’ Microbiota, Still a Mystery?

High throughput and state-of-the-art metagenomics and community fingerprinting, metatranscriptomics, and MS-based metaproteomics identify the bacterial community present on L. pulmonaria as a surprisingly abundant and structurally integrated element of the lichen symbiosis.

Rhizocarpon geographicum Lichen Discloses a Highly Diversified Microbiota Carrying Antibiotic Resistance and Persistent Organic Pollutant Tolerance

A deep functional analysis of the lichen-associated bacterial collection showed the presence of a set of bacterial strains resistant to a wide range of antibiotics and displaying tolerance to Persistent Organic Pollutants (POP).

The Microbiomes of Seven Lichen Genera Reveal Host Specificity, a Reduced Core Community and Potential as Source of Antimicrobials

Results indicate that lichen microbiomes from the Paramo ecosystem are diverse and host-specific but share a taxonomic core and can be a source of new bacterial taxa and antimicrobials.

Microbial Communities of Cladonia Lichens and Their Biosynthetic Gene Clusters Potentially Encoding Natural Products

This work used amplicon sequencing, shotgun metagenomics, and in silico metabolomics together with compound extractions to study reindeer lichens collected from Southern Finland to evaluate the potential of Cladonia species as sources of novel natural products.

One Name – One Fungus: The Influence of Photosynthetic Partners on the Taxonomy and Systematics of Lichenized Fungi

In a few cases in which the photobionts influenced the taxonomy and systematics of lichenized fungi, two different morphotypes of the same species – known as photomorphs – were classified as different species and sometimes different genera.

Exploration of Marine Lichenized Fungi as Bioindicators of Coastal Ocean Pollution in the Boston Harbor Islands National Recreation Area

ABSTRACT. This preliminary exploration of marine lichenized fungi (lichens) as bioindicators of water pollution examined the distribution of intertidal lichen communities in the Boston Harbor Islands

Novel lichen-dominated hypolithic communities in the Namib Desert

The ventral surfaces of translucent rocks from hot desert pavements often harbor hypolithic microbial communities, which are mostly dominated by cyanobacteria. The Namib Desert fog belt supports

Bacterial Communities Associated with the Lichen Symbiosis

These findings confirm the presence of highly structured bacterial communities within lichens and provide additional evidence that these bacteria may serve distinct functional roles within lichen symbioses.

Novel bacteria associated with Arctic seashore lichens have potential roles in nutrient scavenging.

A nutrient-scavenging role of the associate microbiota in the seashore lichen symbiotic association is supported, and several isolates display only a modest level of similarity to their nearest relatives found in GenBank, suggesting that they comprise previously undescribed taxa.

Species-specific structural and functional diversity of bacterial communities in lichen symbioses

The results indicate that bacteria can form highly structured, biofilm-like assemblages on fungal surfaces and reach considerable abundances of up to 108 cells per gram fresh weight in alpine environments.

Photoautotrophic symbiont and geography are major factors affecting highly structured and diverse bacterial communities in the lichen microbiome.

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.

Microbial metacommunities in the lichen-rock habitat.

The results demonstrated that the lichen-rock interfaces are complex habitats, where the macroscopic lichens influence the composition of microbial metacommunities.

Composition, uniqueness and variability of the epiphytic bacterial community of the green alga Ulva australis

Novel bacteria associated with Arctic seashore lichens have potential roles in nutrient scavenging

A denaturing gradient gel electrophoresis based characterization of the composition of the lichen-associated microbiotas indicated that they are markedlyLichen-species-specific and clearly distinguishable from the environmental microbiota represented by control sampling.

Analysis of the Peltigera membranacea metagenome indicates that lichen-associated bacteria are involved in phosphate solubilization.

Analysis of about 30,000 bacterial contigs from the P. membranacea metagenome revealed significant representation of several genes involved in phosphate solubilization and biopolymer degradation, as well as phylogenetic diversity and functional gene composition.

Littoral lichens as a novel source of potentially bioactive Actinobacteria

Results show that littoral lichens are a source of diverse potentially bioactive Actinobacteria, and the diversity was most influenced by the selective media rather than lichen species or the level of lichen thallus association.

Molecular analysis of lichen-associated bacterial communities.

The bacterial communities associated with 11 different lichen samples (belonging to eight different species) from different habitats were investigated and Paenibacillus and Burkholderia phylotypes seem to be common in lichens.
