Romero A.L.N., Moratta M.A.H., Carretero E.M., Rodriguez R.A. & Vento B. (2020): Spatial distribution of biological soil crusts along an aridity gradient in the central-west of Argentina, Journal of Arid Environments, 176: 104099

Biocrusts presented their highest expression in the inter-patches. However, an increase in the level of aridity along the landscape could lead to vascular plants to make a notable influence on the spatial distribution of biocrusts. Our objective was to determine the spatial variation of the vascular plant interactions with biocrusts, and the individual variations of biocrusts and each of its components along a gradient of aridity in Argentina. We worked on three sites following a semiarid-arid-hyperarid … Read more...

Pyrczak-Felczykowska A., Narlawar R., Pawlik A., Guzow-Krzemińska B., Artymiuk D., Hać A., Ryś K., Rendina L.M., Reekie T.A., Herman-Antosiewicz A. & Kassiou M. (2019): Synthesis of usnic acid derivatives and evaluation of their antiproliferative activity against cancer cells, Journal of Natural Products, 82(7): 1768-1778

Usnic acid is a secondary metabolite abundantly found in lichens, for which promising cytotoxic and antitumor potential has been shown. However, knowledge concerning activities of its derivatives is limited. Herein, a series of usnic acid derivatives were synthesized and their antiproliferative potency against cancer cells of different origin was assessed. Some of the synthesized compounds were more active than usnic acid. Compounds 2a and 2b inhibited survival of all tested cancer cell lines in … Read more...

Sidondi L., Odendaal J. P., Walker D. R. & Paulse A. N. (2019): The impact of urban pollution on metal contamination of selected forest pockets in Cape Town, South Africa, Environmental Science and Pollution Research, 26(12): 12537–12549

Urban forests are exposed to metals, such as manganese, copper, and zinc in the atmosphere that originate from anthropogenic activities, that include vehicle-related traffic, industries, construction sites, fossil fuel burning for heating and cooking purposes, and resuspension processes related to urban surfaces. Not only is the rich biodiversity of plant and animal species in forests under threat, but so are the biodiversity of soil, sustaining ecosystem functions, as well as human health. The objective … Read more...

Diederich P., Millanes A.M., Coppins B.J. & Wedin M. (2020): Tremella imshaugiae and T. tubulosae (Tremellomycetes, Basidiomycota), two new lichenicolous fungi on Imshaugia aleurites and Hypogymnia tubulosa, Bulletin de la Société des naturalistes luxembourgeois, 122: 239-246

The new Tremella imshaugiae, lichenicolous on Imshaugia aleurites, is described from Scotland and Maine (USA); it is characterized by small, 0.1–1 mm diam., amber coloured basidiomata not inducing gall-formation, 2–4-celled, mainly longitudinally septate basidia, 15.5–21.5 × 13–16.5 μm, and relatively large, subspherical basidiospores, 6.5–9 × 6.5–8.5 μm; it is sister to T. diploschistina in a phylogeny using ITS and nLSU markers. The new Tremella tubulosae, lichenicolous on Hypogymnia … Read more...

Kumar K., Mishra J.P.N. & Singh R.P. (2020): Usnic acid induces apoptosis in human gastric cancer cells through ROS generation and DNA damage and causes up-regulation of DNA-PKcs and γ-H2A.X phosphorylation, Chemico-Biological Interactions, 315: 108898

Usnic acid, a dibenzofuran derivative found in many lichen species, is reported to have anticancer activity against human gastric cancer. We investigated the molecular alterations associated with anticancer effects of usnic acid against human gastric adenocarcinoma AGS and gastric carcinoma SNU-1 cells. Usnic acid (10–25 μM) treatment to these cells caused a significant increase in mitochondrial membrane depolarization and apoptotic cells. Apoptosis induction was accompanied by an increase in … Read more...

Kemppinen J., Niittynen P., Aalto J., le Roux P.C. & Luoto M. (2019): Water as a resource, stress and disturbance shaping tundra vegetation, Oikos, 128(6): 811-822

Water is crucial for plant productivity and survival as a fundamental resource, but water conditions can also cause physiological stress and mechanical disturbance to vegetation. However, these different influences of water on vegetation patterns have not been evaluated simultaneously. Here, we demonstrate the importance of three water aspects (spatial and temporal variation of soil moisture and fluvial disturbance) for three ecologically and evolutionary distinct taxonomical groups (vascular plants, … Read more...

Yahr R., Royal Botanic Garden Edinburgh Genome Acquisition Lab, Darwin Tree of Life Barcoding collective et al. (2024): The genome sequence of a lichen-forming fungus, Platismatia glauca Linnaeus, 1753 [version 1; peer review: 2 approved], Wellcome Open Research, 9: 457

We present a genome assembly from a specimen of Platismatia glauca (lichen-forming fungus; Ascomycota; Lecanoromycetes; Lecanorales; Parmeliaceae). The genome sequence is 33.2 megabases in span. Most of the assembly is scaffolded into 21 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 95.06 kilobases in length. Keywords: Platismatia glauca, lichen-forming fungus, genome sequence, chromosomal, Lecanorales. Read more...
