Kerr M. & Leavitt S.D. (2023): A custom regional DNA barcode reference library for lichen-forming fungi of the Intermountain West, USA, increases successful specimen identification - Journal of Fungi, 9(7): 741 [14 p.]

DNA barcoding approaches provide powerful tools for characterizing fungal diversity. However, DNA barcoding is limited by poor representation of species-level diversity in fungal sequence databases. Can the development of custom, regionally focused DNA reference libraries improve species-level identification rates for lichen-forming fungi? To explore this question, we created a regional ITS database for lichen-forming fungi (LFF) in the Intermountain West of the United States. The custom database … Read more...

Daminova A.G., Rassabina A.E., Khabibrakhmanova V.R., Beckett R.P. & Minibayeva F.V. (2023): Topography of UV-melanized thalli of Lobaria pulmonaria (L.) Hoffm. - Plants, 12(14): 2627 [12 p.]

Lichens are unique extremophilic organisms due to their phenomenal resistance to adverse environmental factors, including ultraviolet (UV) irradiation. Melanization plays a special role in the protection of lichens from UV-B stress. In the present study, we analyzed the binding of melanins with the components of cell walls of the mycobiont of the upper cortex in the melanized lichen thalli Lobaria pulmonaria. Using scanning electron and atomic force microscopy, the morphological and nanomechanical … Read more...

Naksuwankul K. & Lumbsch H. T. (2023): Saxicolous species of the lichenized fungal genus Porina (Ascomycota; Porinaceae) new records and a key to species in Thailand - Taiwania, 68: 261-264

Species of the genus Porina can growth on various substrates, including siliceous rocks. This study focus on saxicolous species, including two new records for Thailand; P. leptalea and P. nucula. Ten species of Porina were found in Thailand and a key to the identification of the species is provided. Read more...

Varlı M., Lee E.-Y., Yang Y., Zhou R., Taş İ., Pulat S., Gamage C. D. B., Park S.-Y., Hur J.-S., Nam S.-J. & Kim H (2023): 1′-O-methyl-averantin isolated from the endolichenic fungus Jackrogersella sp. EL001672 suppresses colorectal cancer stemness via sonic Hedgehog and Notch signaling - Scientific Reports, 13: 2811

Endolichenic fungi are host organisms that live on lichens and produce a wide variety of secondary metabolites. Colorectal cancer stem cells are capable of self-renewal and differentiation into cancer cells, which makes cancers difficult to eradicate. New alternative therapeutics are needed to inhibit the growth of tumor stem cells. This study examined the ability of an extract of Jackrogersella sp. EL001672 (derived from the lichen Cetraria sp.) and the isolated compound 1′-O-methyl-averantin … Read more...

Yang Q., Wang Y., Lücking R., Lumbsch H. T., Du Z., Chen Y., Bai M., Ren D., Wei J., Li H., Wang Y. & Wei X. (2023): The Jurassic epiphytic macrolichen Daohugouthallus reveals the oldest lichen-plant interaction in a Mesozoic forest ecosystem - iScience, 26: 105770

Lichens are well known as pioneer organisms or stress-tolerant extremophiles, potentially playing a core role in the early formation of terrestrial ecosystems. Epiphytic macrolichens are known to contribute to the water- and nutrient cycles in forest ecosystem. But due to the scarcity of fossil record, the evolutionary history of epiphytic macrolichens is poorly documented. Based on new fossil of Jurassic Daohugouthallus ciliiferus, we demonstrate the hitherto oldest known macrolichen inhabited a … Read more...

Rodríguez-Arribas C., Martínez I., Aragón G., Zamorano-Elgueta C., Cavieres L. & Prieto M. (2023): Specialization patterns in symbiotic associations: A community perspective over spatial scales - Ecology and Evolution, 13: e10296 [16 p.]

Specialization, contextualized in a resource axis of an organism niche, is a core concept in ecology. In biotic interactions, specialization can be determined by the range of interacting partners. Evolutionary and ecological factors, in combination with the surveyed scale (spatial, temporal, biological, and/or taxonomic), influence the conception of specialization. This study aimed to assess the specialization patterns and drivers in the lichen symbiosis, considering the interaction between the principal … Read more...

Økland T., Halvorsen R., Lange T., Nordbakken J.-F. & Clarke N. (2023): Climate change drives substantial decline of understorey species richness and abundance in Norway spruce forests during 32 years of vegetation monitoring - Journal of Vegetation Science, 34: e13191 [22 p.]

Questions Observations in permanent forest vegetation plots in Norway and elsewhere indicate that complex changes have taken place over the period 1988–2020. These observations are summarised in the “climate-induced understorey change (CIUC)” hypothesis, i.e. that the understorey vegetation of old-growth boreal forests in Norway undergoes significant long-term changes and that these changes are consistent with the ongoing climate change as an important driver. Seven testable predictions were … Read more...

Perini L., Gostinčar C., Likar M., Frisvad J.C., Kostanjšek R., Nicholes M., Williamson C., Anesio A.M., Zalar P. & Gunde‑Cimerman N. (2023): Interactions of fungi and algae from the Greenland Ice Sheet - Microbial Ecology, 86: 282–296

Heavily pigmented glacier ice algae Ancylonema nordenskiöldii and Ancylonema alaskanum (Zygnematophyceae, Streptophyta) reduce the bare ice albedo of the Greenland Ice Sheet, amplifying melt from the largest cryospheric contributor to eustatic sea-level rise. Little information is available about glacier ice algae interactions with other microbial communities within the surface ice environment, including fungi, which may be important for sustaining algal bloom development. To address this … Read more...

Zhou R., Zhang L., Zeng B., Zhou Y., Jin W. & Zhang G. (2023): A novel self‑purifed auxiliary protein enhances the lichenase activity towards lichenan for biomass degradation - Applied Microbiology and Biotechnology , 107: 4553–4566

Due to the complex composition of lichenan, lichenase alone cannot always hydrolyze it efciently. Carbohydrate-binding modules (CBMs) and lytic polysaccharide monooxygenases (LPMOs) have been confrmed to increase the hydrolysis efciency of lichenases. However, their practical application was hampered by the complex and costly preparation procedure, as well as the poor stability of LPMOs. Herein, we discovered a novel and stable auxiliary protein named SCE to boost the hydrolysis efciency. … Read more...

Özkök E.A. & Çobanoğlu G. (2023): Spatial evaluation of air quality by biomonitoring of toxic element accumulation in lichens in urban green areas and nature parks on the Anatolian side of Istanbul - Environmental Monitoring and Assessment , 195: 908 [14 p.]

The city of Istanbul is constantly exposed to air pollution due to its high population, heavy traffic — sea and air transport — and urban industry. This study basically aims to determine the recent level of airborne heavy metals, using lichen biomonitoring method. The cosmopolitan foliose lichen Xanthoria parietina growing abundantly on trees was sampled from 16 urban green spaces in 8 districts on the Anatolian side of Istanbul. Multi-element analysis by ICP-MS was applied to … Read more...
