Metabolic responses of epiphytic lichen Ramalina farinacea to cadmium (Cd) and/or nitric oxide (NO) scavenger (cPTIO) were studied. Accumulation of Cd and other metallic nutrients was not affected by cPTIO while total and absorbed amounts differed. Cd-induced NO formation was suppressed by cPTIO but ROS signal was synergistically enhanced, confirming that NO is essential to keep ROS under control. Read More

Division of Rheumatology, Department of Internal Medicine, University of Michigan, Ann Arbor, MI 48109, USA. Electronic address:

Type I interferons (IFNs) are an immunomodulatory class of cytokines that serve to protect against viral and bacterial infection. In addition, mounting evidence suggests IFNs, particularly type I but also IFNγ, are important to the pathogenesis of autoimmune and inflammatory skin diseases, such as cutaneous lupus erythematosus (CLE). Understanding the role of IFNs is relevant to anti-viral responses in the skin, skin biology, and therapeutics for these IFN-related conditions. Read More

Lichen-associated bacterium, a novel bioresource of polyhydroxyalkanoate (PHA) production and simultaneous degradation of naphthalene and anthracene.

J Microbiol Biotechnol 2018 Nov 16. Epub 2018 Nov 16.

Korean Lichen Research Institute, Sunchon National University, Suncheon, Republic of Korea.

Lichens are generally known as self-sufficient symbiotic life-form between fungus and algae/cyanobacteria, also provide shelter for a wide range of beneficial bacteria. Besides, bacterial derived biodegradable polyhydroxyalkanoate (PHA) is currently grabbing the attention of many researchers as a promising alternative of non-degradable plastics. This study was conducted to develop a new method of PHA production using unexplored lichen-associated bacteria, which can simultaneously degrade two ubiquitous industrial toxins, anthracene and naphthalene.

Department of Dermatology, Kyorin University School of Medicine, 6-20-2, Shinkawa Mitaka, Tokyo, 181-8611, Japan.

No previous studies have convincingly linked sweating disturbance with the subsequent development of lichen planus (LP). Therefore, we investigated whether sweating disturbance could be specifically detected in LP lesions and how it could trigger lesion development. We utilized the impression mold technique (IMT), which allows accurate quantification of individual sweat glands/ducts actively delivering sweat in a well-defined location, to evaluate sweating disturbance in LP lesions.

The review discusses the data on vitamin D accumulation in animals, plants, and other organisms. 7-Dehydrocholesterol (7-DHC) and ergosterol are considered to be the only true precursors of vitamin D, although even vitamin D (ergocalciferol) is not fully comparable to vitamin D (cholecalciferol) in regard to their functions. These precursors are converted by UV radiation into the corresponding D vitamins. Read More

Soil moisture dynamics under two rainfall frequency treatments drive early spring CO gas exchange of lichen-dominated biocrusts in central Spain.

PeerJ 2018 16;6:e5904. Epub 2018 Nov 16.

Freie Universität Berlin, Department of Biodiversity/Theoretical Ecology, Institute of Biology, Berlin, Germany.

Background: Biocrusts, communities dominated by mosses, lichens, cyanobacteria, and other microorganisms, largely affect the carbon cycle of drylands. As poikilohydric organisms, their activity time is often limited to short hydration events. The photosynthetic and respiratory response of biocrusts to hydration events is not only determined by the overall amount of available water, but also by the frequency and size of individual rainfall pulses.

Nitrogen-Fixing Bacteria Associated with Cyanolichens and Chlorolichens.

Molecules 2018 Nov 25;23(12). Epub 2018 Nov 25.

Laboratory of Microbial Ecology, Department of Ecological Sciences, Faculty of Sciences, Universidad de Chile, Santiago 7800003, Chile.

Lichens have been extensively studied and described; however, recent evidence suggests that members of the bacterial community associated with them could contribute new functions to the symbiotic interaction. In this work, we compare the nitrogen-fixing guild associated with bipartite terricolous lichens with different types of photobiont: cyanolichens and chlorolichens. Since cyanobacteria contribute nitrogen to the symbiosis, we propose that chlorolichens have more diverse bacteria with the ability to fix nitrogen compared to cyanolichens. Read More
