Varlı M., Ahn E.-J., Bhosle S.R., Moon K,-S., Ha H.-H. & Kim H. (2025): Targeting heat shock protein 90 with usnic acid relieves immune suppression via aryl hydrocarbon receptor-mediated mechanisms in lung cancer, Molecular Biomedicine, 6: 81 [20 p.]

Immune evasion in lung cancer is closely associated with the dysregulation of molecular chaperones and immunoregulatory pathways. Heat shock protein 90 (HSP90), which is frequently overexpressed in lung cancer and correlates with poor prognosis, has emerged as a promising therapeutic target. Here, we investigated whether targeting the HSP90–aryl hydrocarbon receptor (AhR) axis with usnic acid (UA) could suppress immune evasion mechanisms in lung cancer. Through target prediction and molecular docking, … Read more...

Giordani P., Calderisi G., Cogoni D. & Fenu G. (2025): Asynchronous postfire recovery dynamics between epilithic lichens and vascular plants in Mediterranean ecosystems, Journal of Environmental Management, 394: 127645 [13 p.]

Wildfire has been a recurring natural disturbance within the Mediterranean Basin, leading to the evolution of adaptive traits in some plant species that enable them to survive or have high resilience fires. This study investigates the short-term resilience of vascular plants and epilithic lichens in Sardinia, Italy, following a Mediterranean megafire in 2021, focusing on taxonomic and functional diversity. Using a stratified random sampling method, 59 plots (40 burnt and 19 control) were analysed … Read more...

Kalefetoğlu Macar T., Macar O., Kınalıoğlu K., Yalçın E. & Çavuşoğlu K. (2025): Ramalina farinacea mitigates cytogenotoxicity and physiological, biochemical, and anatomical alterations induced by nickel in Allium cepa, Scientific Reports, 15: 35527 [15 p.]

Environmental contamination by heavy metals is a growing concern due to their adverse impacts on plant health and ecological stability. In this study, the potential of Ramalina farinacea (L.) Ach. lichen extract to mitigate the toxic effects of nickel chloride (NiCl₂) on Allium cepa L. was investigated. The bulbs were exposed to various treatment groups, and a series of physiological, cytogenetic, biochemical, and anatomical analyses were performed. Throughout the experimental period, the control … Read more...

Sandino J., Barthelemy J., Doshi A., Randall K., Robinson S.A., Bollard B. & Gonzalez F. (2025): Drone hyperspectral imaging and artificial intelligence for monitoring moss and lichen in Antarctica, Scientific Reports, 15: 27244 [23 p.]

Uncrewed aerial vehicles (UAVs) have become essential for remote sensing in extreme environments like Antarctica, but detecting moss and lichen using conventional red, green, blue (RGB) and multispectral sensors remains challenging. This study investigates the potential of hyperspectral imaging (HSI) for mapping cryptogamic vegetation and presents a workflow combining UAVs, ground observations, and machine learning (ML) classifiers. Data collected during a 2023 summer expedition to Antarctic Specially … Read more...

Noor A., Saba M., Akram W., Ullah M. & Asif M. (2025): Two novel species of Lecanora genus (Ascomycota, Lecanoraceae) from Western Himalaya, Pakistan, Phytotaxa, 722(3): 247–259

During this study we investigate two new species of crustose lichen Lecanora ahmadii sp. nov. and Lecanora haripurensis sp. nov. from district Haripur and Murree, Pakistan. Based on morphological and molecular phylogenetic analysis. Lecanora haripurensis sp. nov. is characterized by light greyish white to rough white thallus, lecanorine, black sessile, irregular apothecia, falls in sister clade to species Lecanora epibryon. The other specimen Lecanora ahmadiisp. nov. is characterized by verruculose … Read more...

Wu W., Jiang. S.-H., Zhao S., Fu S.-B. & Meng Q.-F. (2025): A new species and a new record of the lichen family Graphidaceae from China, Phytotaxa, 722(3): 269–278

Based on morphological, chemical and molecular data, a new species, Platygramme guizhouensis is described to science, and Phaeographis decipiens is reported as new record to China. Platygramme guizhouensis features lirelliform apothecia with discs open, black, epruinose, proper exciple apically carbonized, wedge-shaped. Asci cylindrical to clavate, 8-spored. Ascospores brown, elongate-ellipsoid, 9–12 transverse septa, I+ violet-purple. Detailed descriptions and illustrations of the new species … Read more...

Elvebakk A., Knight A. & Ford M. (2025): Psoroma urupukapukianum sp. nov. and squamulose Pannaria lichen species in Aotearoa / New Zealand, Perspectives in Biodiversity, 3(1): 44–58

Psoroma urupukapukianum is described from Urupukapuka Island in the Bay of Islands, Te Tai Tokerau / Northland, Aotearoa / New Zealand based on two herbarium collections made in 1980. It has recently been sought at its type locality without success. The species is corticolous and squamulose, developing into a crust of gymnidia, where c. 3/4 represent the chloromorph and the remaining parts are conspicuous cephalodia with the same external morphology as the chloromorph. The species lacks lichen substances … Read more...

Mulroy M., Dart J., Williams C.B., Reese Næsborg R., Fryday A., Johnston S., Kellman K. & Rajakaruna N. (2025): A comparative study of lichen and bryophyte communities on sandstone and ultramafic bedrocks along a maritime gradient in central California, Journal of Vegetation Science, 36(5): e70072 [15 p.]

Aims: Lichens and bryophytes are an often overlooked, yet dominant biotic component of rock outcrops and other lithic habitats. Saxicolous lichen and bryophyte communities are frequently species-rich and play important ecological roles, including rock weathering, soil formation, and vascular plant recruitment. In this study, we test whether saxicolous communities differ between two substrate types along a coastal to inland spatial gradient. Location: Ultramafic and sandstone rock outcrops in central … Read more...

Garfias-Gallegos D., Pardo-De la Hoz C.J., Haughland D.L., Magain N., Aguero B., Miadlikowska J. & Lutzoni F. (2025): Central metabolism and development are rewired in lichenized cyanobacteria, The ISME Journal, 19(1): wraf166 [12 p.]

Nostoc cyanobacteria are among the few organisms capable of fixing both carbon and nitrogen. These metabolic features are essential for the cyanolichen symbiosis, where Nostoc supplies both carbon (as glucose) and nitrogen (as ammonium) to a cyanolichen-forming fungal partner. This nutrient flow was established by seminal biochemical studies published in the 20th century. Since then, cyanolichen metabolism has received little attention, and the molecular mechanisms that underlie the physiology of … Read more...

Moriyama T., Endo C., Tanaka C. & Isagi Y. (2025): Ecological and phylogenetic re-assessment of the bryophilous ascomycete Monascostroma sphagnophilum revealed a new style of fungus-alga interaction in the order Capnodiales, Symbiosis, 96: 305–319

Monascostroma sphagnophilum is an ascomycetous fungus that has been reported to grow on Sphagnum, accompanied by algal colonies. Its relationship with the co-existing algae has been poorly investigated. We collected ascomata on gelatinous algal colonies found on Leucobryum sp. in Japan, and morphologically and phylogenetically identified them as M. sphagnophilum. This is the first report of this fungus from Asia. Phylogenetic analysis of the fungal isolates confirmed that they belong to Capnodiales, … Read more...
