Tanunchai B., Schroeter S.A., Ji L., Wahdan S.F.M., Hossen S., Lehnert A.-S., Grünberg H., Gleixner G., Buscot F., Schulze E.-D., Noll M. & Purahong W. (2022): More than you can see: Unraveling the ecology and biodiversity of lichenized fungi associated with leaves and needles of 12 temperate tree species using high-throughput sequencing - Frontiers in Microbiology, 13: 907531 [17 p.]

Currently, lichen surveys are generally based on the examination of fruiting bodies. Lichens in the mycelial stage, in spores, or awaiting conditions for fruiting body formation are usually overlooked, even though they are important for maintaining biodiversity and ecosystem functions. This study aimed to explore the lichenized fungal community composition and richness associated with leaves and needles of 12 temperate tree species using Illumina MiSeq-based amplicon sequencing of the internal … Read more...

Cai L., Zheng Y., Chu Y., Lin Y., Liu L. & Zhang G. (2022): The synergism of lytic polysaccharide monooxygenases with lichenase and their co-immobilization on silica nanospheres for green conversion of lichen biomass - Frontiers in Nutrition, 9: 970540 [12 p.]

Enzyme-assisted valorization of lichenan represents a green and sustainable alternative to the conventional chemical industry. The recently discovered lytic polysaccharide monooxygenases (LPMOs) are essential components of state-of-the-art enzyme cocktails for lichenin bioconversion. The LPMOs named SpyTag fused LPMOs (AST) from Chaetomium globosum was functionally expressed in E. coli and exhibited 1.25-fold synergism with lichenase, whereas AST alone produced no detectable reducing sugars. … Read more...

Muster C., Leiva D., Morales C., Grafe M., Schloter M., Carú M. & Orlando J. (2022): Peltigera frigida lichens and their substrates reduce the influence of forest cover change on phosphate solubilizing bacteria - Frontiers in Microbiology, 13: 843490 [12 p.]

Phosphorus (P) is one of the most critical macronutrients in forest ecosystems. More than 70 years ago, some Chilean Patagonian temperate forests suffered wildfires and the subsequent afforestation with foreign tree species such as pines. Since soil P turnover is interlinked with the tree cover, this could influence soil P content and bioavailability. Next to soil microorganisms, which are key players in P transformation processes, a vital component of Patagonian temperate forest are lichens, … Read more...

Varlı M., Pham H.T., Kim S.-M., Taş İ., Gamage C.D.B., Zhou R., Pulat S., Park S.-Y., Sesal N.C., Hur J.-S., Kang K.B. & Kim H. (2022): An acetonic extract and secondary metabolites from the endolichenic fungus Nemania sp. EL006872 exhibit immune checkpoint inhibitory activity in lung cancer cell - Frontiers in Pharmacology, 13: 986946 [13 p.]

Background: Endolichenic fungi (ELF), which live the inside the lichen thallus, contain many secondary metabolites that show various biological activities. Recent studies show that lichen and ELF secondary metabolites have antioxidant, antibacterial, antifungal, cytotoxic, and anticancer activities. Purpose: Here, the effects of an ELF extract and its bioactive compounds were investigated on the H1975 cell line focusing on immune checkpoint marker inhibition. Methods: An ELF was isolated from … Read more...

Santos A.M., Vitorino L.C., Cruvinel B.G., Ávila R.G., Vasconcelos Filho S.C., Batista P.F. & Bessa L.A. (2022): Impacts of Cd pollution on the vitality, anatomy and physiology of two morphologically different lichen species of the genera Parmotrema and Usnea, evaluated under experimental conditions - Diversity, 14(11): 926 [29 p.]

The heavy metal Cd accumulates in trophic chains, constituting a toxic element for photosynthesizing organisms, including the algal photobionts of lichen. Thus, as lichens respond differently to heavy metal toxicity, we hypothesized that the species Parmotrema tinctorum and Usnea barbata, commonly sampled in the Cerrado ecoregion, could be sensitive to Cd and, therefore, be used to biomonitor the dispersion of this metal. We also aimed to indicate the responsiveness of biological markers to Cd in … Read more...

Harnesk D. (2022): The decreasing availability of reindeer forage in boreal forests during snow cover periods: A Sámi pastoral landscape perspective in Sweden - Ambio, 51: 2508–2523

This paper argues that Sámi reindeer pastoralism in Sweden is highly stressed during the critical snow cover periods due to large-scale human interventions, especially forestry, and that these have over time significantly worsened the ecological conditions for natural grazingbased responses to changing snow conditions caused by climate change. Informed by a literature review, the paper conceptualises two, overlapping ecological dynamics that shape the availability of lichen as key forage … Read more...

Ortiz-Moreno M.L., Moncada B., Vasco-Palacios A.M., de Almeida R.F. & Gaya E. (2022): Fungi in Colombian and international biological collections - In: de Almeida R.F., Lücking R., Vasco-Palacios A.M., Gaya E. & Diazgranados M. (eds), Catalogue of Fungi of Colombia, p. 189–207, Kew Publishing, Royal Botanic Gardens, Kew

Colombia ranks among the 17 countries considered megadiverse, hosting almost 10% of the planet’s biodiversity and only being surpassed by Brazil, a country seven times larger than Colombia. Unfortunately, fungi are mostly left out of these counts. One of the issues faced when attempting to report the fungal diversity in Colombia is the inability to account for the fungal specimens scattered in national and international collections, which are often not properly curated or digitised. In this … Read more...

Ai M., Zhong Q., Scheidegger C., Wang L. & Wang X. (2022): Revision of Dimelaena Norman (Caliciaceae, Ascomycota) species containing usnic acid reveals a new species and a new combination from China - Phytotaxa, 574(4): 259–272

Dimelaena tibetica is described as a species new to science, characterized by a grayish yellow surface, usually with a covering of white pruina, a crustose thallus, areolate at center, radiate-plicate at margin, adnate apothecia and lacking gyrophoric acid. It differs from other usnic acid-containing Dimelaena species by its plane marginal lobes and adnate apothecia. Based on the study of fresh specimens from the environment of the type locality, Dimelaena altissima is proposed as a new combination. … Read more...

Wang H., Xuan M., Huang C. & Wang C. (2022): Advances in research on bioactivity, toxicity, metabolism, and pharmacokinetics of usnic acid in vitro and in vivo - Molecules, 27(21): 7469 [22 p.]

Lichens are among the most widely distributed plants on earth and have the longest growth cycle. Usnic acid is an abundant characteristic secondary metabolite of lichens and the earliest lichen compound used commercially. It has diverse pharmacological activities, such as anti-inflammatory, antibacterial, antiviral, anticancer, antioxidant, and photoprotective effects, and promotes wound healing. It is widely used in dietary supplements, daily chemical products (fodder, dyes, food, perfumery, and … Read more...
