Ecology of endolithic lichens colonizing granite in continental Antarctica [PDF]

, 2005
In this study, the symbiont cells of several endolithic lichens colonizing granite in continental Antarctica and the relationships they have with the abiotic environment were analyzed in situ, in order to characterize the microecosystems integrating ...

Population genetics of lichen-forming fungi – a review [PDF]

The Lichenologist, 2010
AbstractPopulation genetics investigates the distribution of genetic variation in natural populations and the genetic differentiation among populations. Lichen-forming fungi are exciting subjects for population genetic studies due to their obligate symbiosis with a green-algal and/or cyanobacterial photobiont, and because their different reproductive ...

Molecular studies on cyanobacterial diversity in lichen symbioses

MycoKeys, 2013
Symbioses between cyanobacteria and lichen-forming fungi occur worldwide in a wide range of terrestrial environments, ranging from tropical rainforests to hot and cold deserts. The evolutionary success of these symbioses is evident from the wide range of

Culturable Diversity of Lichen-Associated Yeasts through Enrichment Strategies

Ecologies, 2023
Lichens are symbiotic partnerships between a filamentous fungus and a photosymbiotic “alga”. Studies show that lichens harbor endothallic fungi, but that some taxa have been difficult to isolate from the main filamentous thallus-forming fungus and other ...

Discovery and excavation of lichen bioactive natural products

Frontiers in Microbiology, 2023
Lichen natural products are a tremendous source of new bioactive chemical entities for drug discovery. The ability to survive in harsh conditions can be directly correlated with the production of some unique lichen metabolites.

Deciphering the biosynthetic pathways of lichen acids. [PDF]

New Phytol
Summary Depsides and depsidones are polyketide‐derived lichen acids widely distributed in lichen thalli, yet the biosynthetic gene clusters (BGCs) responsible for their production remain poorly understood. To address this gap, we investigated the diversity and evolutionary relationships of polyketide BGCs in lichens.

New Records of Lichen-Forming Fungi from Kenya

Journal of East African Natural History, 2012
Diversity of tropical lichen-forming fungi, especially crustose lichens is currently poorly known. Since lichens are important bioindicators of air pollution, forest health, and climate change, we addressed the lichen diversity in Kenya. Our study focused on the diversity of lichen-forming fungi in the Mount Kenya montane forests, where we sampled ...

Genome mining as a biotechnological tool for the discovery of novel biosynthetic genes in lichens

Frontiers in Fungal Biology, 2022
Natural products (NPs) and their derivatives are a major contributor to modern medicine. Historically, microorganisms such as bacteria and fungi have been instrumental in generating drugs and lead compounds because of the ease of culturing and ...

Lichen-forming fungi in postindustrial habitats involve alternative photobionts

Mycologia, 2020
Mycobionts of many lichen genera appear to demonstrate strong selectivity in the choice of algal partner. The biological properties of a photobiont and its availability in an environment significantly determine the habitat requirements of lichens. Flexibility in photobiont choice extends the ecological amplitude of lichens; therefore, it may constitute
