Filter-feeders have differential bottom-up impacts on green and brown food webs.

Oecologia 2021 Jan 2;195(1):187-198. Epub 2021 Jan 2.

Department of Crop, Soil and Environmental Sciences, Auburn University, Auburn, AL, 36849, USA.

Nutrient recycling by consumers can strongly impact nutrient availability for autotrophic and heterotrophic microbes, thus impacting functions such as primary production and decomposition. Filter-feeding freshwater mussels form dense, multispecies assemblages in aquatic ecosystems and have been shown to play a critical role in nutrient cycling. Mussel excretion can enhance benthic primary production and influence algal species composition. Read More

Upconversion Nanodevice-Assisted Healthy Molecular Photocorrection.

ACS Biomater Sci Eng 2021 01 24;7(1):291-298. Epub 2020 Dec 24.

Institute of Nano Science and Technology, Habitat Centre, Phase-10, Sector-64, Mohali 160062, Punjab, India.

Mushrooms are rich in ergosterol, a precursor of ergocalciferol, which is a type of vitamin D. The conversion of ergosterol to ergocalciferol takes place in the presence of UV radiation by the cleavage of the "B-ring" in the ergosterol. As the UV radiation cannot penetrate deep into the tissue, only minimal increase occurs in sunlight. Read More

Site fertility and soil water-table level affect fungal biomass production and community composition in boreal peatland forests.

Environ Microbiol 2020 Dec 21. Epub 2020 Dec 21.

Natural Resources Institute Finland (LUKE), Natural Resources, Latokartanonkaari 9, Helsinki, FI-00790, Finland.

A substantial amount of below-ground carbon (C) is suggested to be associated with fungi, which may significantly affect the soil C balance in forested ecosystems. Ergosterol from in-growth mesh bags and litterbags was used to estimate fungal biomass production and community composition in drained peatland forests with differing fertility. Extramatrical mycelia (EMM) biomass production was generally higher in the nutrient-poor site, increased with deeper water table level and decreased along the length of the recovery time. Read More

Front Microbiol 2020 26;11:559975. Epub 2020 Nov 26.

Department of Microbiology & Immunology, Georgetown University Medical Center, Washington, DC, United States.

The cyclic adenosine 3',5'-monophosphate (cAMP)/protein kinase A (PKA) pathway of responds to nutrient availability to coordinate a series of cellular processes for its replication and survival. The elevation of cAMP for PKA signaling must be both transitory and tightly regulated. Otherwise, any abnormal cAMP/PKA pathway would disrupt metabolic potential and ergosterol synthesis and promote a stress response. Read More

Hydroxylumisterols, Photoproducts of Pre-Vitamin D3, Protect Human Keratinocytes against UVB-Induced Damage.

Int J Mol Sci 2020 Dec 9;21(24). Epub 2020 Dec 9.

Department of Dermatology, University of Alabama at Birmingham, Birmingham, AL 35294, USA.

Lumisterol (L3) is a stereoisomer of 7-dehydrocholesterol and is produced through the photochemical transformation of 7-dehydrocholesteol induced by high doses of UVB. L3 is enzymatically hydroxylated by CYP11A1, producing 20(OH)L3, 22(OH)L3, 20,22(OH)2L3, and 24(OH)L3. Hydroxylumisterols function as reverse agonists of the retinoic acid-related orphan receptors α and γ (RORα/γ) and can interact with the non-genomic binding site of the vitamin D receptor (VDR).

Variation in hyphal production rather than turnover regulates standing fungal biomass in temperate hardwood forests.

Ecology 2021 03 1;102(3):e03260. Epub 2021 Feb 1.

Department of Forest Mycology and Plant Pathology, Uppsala BioCenter, Swedish University of Agricultural Sciences, Uppsala, Sweden.

Soil fungi link above- and belowground carbon (C) fluxes through their interactions with plants and contribute to C and nutrient dynamics through the production, turnover, and activity of fungal hyphae. Despite their importance to ecosystem processes, estimates of hyphal production and turnover rates are relatively uncommon, especially in temperate hardwood forests. We sequentially harvested hyphal ingrowth bags to quantify the rates of Dikarya (Ascomycota and Basidiomycota) hyphal production and turnover in three hardwood forests in the Midwestern United States, where plots differed in their abundance of arbuscular (AM)- vs. Read More

Production and turnover of mycorrhizal soil mycelium relate to variation in drought conditions in Mediterranean Pinus pinaster, Pinus sylvestris and Quercus ilex forests.

New Phytol 2021 05 29;230(4):1609-1622. Epub 2020 Nov 29.

Joint Research Unit CTFC - AGROTECNIO, Av. Alcalde Rovira Roure 191, Lleida, 25198, Spain.

In forests, ectomycorrhizal mycelium is pivotal for driving soil carbon and nutrient cycles, but how ectomycorrhizal mycelial dynamics vary in ecosystems with drought periods is unknown. We quantified the production and turnover of mycorrhizal mycelium in Mediterranean Pinus pinaster, Pinus sylvestris and Quercus ilex forests and related the estimates to standardised precipitation index (SPI), to study how mycelial dynamics relates to tree species and drought-moisture conditions. Production and turnover of mycelium was estimated between July and February, by quantifying the fungal biomass (ergosterol) in ingrowth mesh bags and using statistical modelling. Read More

Lipid Rafts, Sphingolipids, and Ergosterol in Yeast Vacuole Fusion and Maturation.

Front Cell Dev Biol 2020 3;8:539. Epub 2020 Jul 3.

Department of Biochemistry, University of Illinois at Urbana-Champaign, Urbana, IL, United States.

The lysosome-like vacuole is a useful model for studying membrane fusion events and organelle maturation processes utilized by all eukaryotes. The vacuolar membrane is capable of forming micrometer and nanometer scale domains that can be visualized using microscopic techniques and segregate into regions with surprisingly distinct lipid and protein compositions. These lipid raft domains are liquid-ordered (L ) like regions that are rich in sphingolipids, phospholipids with saturated acyl chains, and ergosterol. Read More

Department of Renewable Resources, University of Alberta, Edmonton, AB, T6G 2E3, Canada.

Disturbances have altered community dynamics in boreal forests with unknown consequences for belowground ecological processes. Soil fungi are particularly sensitive to such disturbances; however, the individual response of fungal guilds to different disturbance types is poorly understood. Here, we profiled soil fungal communities in lodgepole pine forests following a bark beetle outbreak, wildfire, clear-cut logging, and salvage-logging. Read More

Autotrophic and Heterotrophic Growth Conditions Modify Biomolecole Production in the Microalga (Cyanidiophyceae, Rhodophyta).

Mar Drugs 2020 Mar 18;18(3). Epub 2020 Mar 18.

Department of Agricultural Science, University of Naples Federico II, Via Università, Portici, Naples, Italy.

Algae have multiple similarities with fungi, with both belonging to the Thallophyt, a polyphyletic group of non-mobile organisms grouped together on the basis of similar characteristics, but not sharing a common ancestor. The main difference between algae and fungi is noted in their metabolism. In fact, although algae have chlorophyll-bearing thalloids and are autotrophic organisms, fungi lack chlorophyll and are heterotrophic, not able to synthesize their own nutrients. Read More

Application of monoclonal antibodies in quantifying fungal growth dynamics during aerobic spoilage of silage.

Microb Biotechnol 2020 07 10;13(4):1054-1065. Epub 2020 Mar 10.

Rothamsted Research, North Wyke, Okehampton, Devon, EX20 2SB, UK.

Proliferation of filamentous fungi following ingress of oxygen to silage is an important cause of dry matter losses, resulting in significant waste. In addition, the production of mycotoxins by some filamentous fungi poses a risk to animal health through mycotoxicosis. Quantitative assessment of fungal growth in silage, through measurement of ergosterol content, colony-forming units or temperature increase is limiting in representing fungal growth dynamics during aerobic spoilage due to being deficient in either representing fungal biomass or being able to identify specific genera.
