Addressing widespread misidentifications of traditional medicinal mushrooms in Sanghuangporus (Basidiomycota) through ITS barcoding and designation of reference sequences.

IMA Fungus 2021 Apr 15;12(1):10. Epub 2021 Apr 15.

State Key Laboratory of Mycology, Institute of Microbiology, Chinese Academy of Sciences, Beijing, 100101, China.

"Sanghuang" refers to a group of important traditionally-used medicinal mushrooms belonging to the genus Sanghuangporus. In practice, species of Sanghuangporus referred to in medicinal studies and industry are now differentiated mainly by a BLAST search of GenBank with the ITS barcoding region as a query. However, inappropriately labeled ITS sequences of "Sanghuang" in GenBank restrict accurate species identification and, to some extent, the utilization of these species as medicinal resources.

Enhanced Lignocellulolytic Enzyme Activities on Hardwood and Softwood during Interspecific Interactions of White- and Brown-Rot Fungi.

J Fungi (Basel) 2021 Mar 31;7(4). Epub 2021 Mar 31.

Department of Microbiology, Faculty of Agriculture and Forestry, University of Helsinki, FI-00014 Helsinki, Finland.

Wood decomposition is a sophisticated process where various biocatalysts act simultaneously and synergistically on biopolymers to efficiently break down plant cell walls. In nature, this process depends on the activities of the wood-inhabiting fungal communities that co-exist and interact during wood decay. Wood-decaying fungal species have traditionally been classified as white-rot and brown-rot fungi, which differ in their decay mechanism and enzyme repertoire. Read More

Ophiostomatalean fungi associated with wood boring beetles in South Africa including two new species.

Antonie Van Leeuwenhoek 2021 Mar 6. Epub 2021 Mar 6.

Department of Biochemistry, Genetics and Microbiology, Forestry and Agricultural Biotechnology Institute, University of Pretoria, Pretoria, South Africa.

Ambrosia beetles are small wood inhabiting members of the Curculionidae that have evolved obligate symbioses with fungi. The fungal symbionts concentrate nutrients from within infested trees into a usable form for their beetle partners, which then utilize the fungi as their primary source of nutrition. Ambrosia beetle species associate with one or more primary symbiotic fungal species, but they also vector auxiliary symbionts, which may provide the beetle with developmental or ecological advantages.

Function of sesquiterpenes from Schizophyllum commune in interspecific interactions.

PLoS One 2021 15;16(1):e0245623. Epub 2021 Jan 15.

Microbial Communication, Institute of Microbiology, Friedrich Schiller University Jena, Jena, Germany.

Wood is a habitat for a variety of organisms, including saprophytic fungi and bacteria, playing an important role in wood decomposition. Wood inhabiting fungi release a diversity of volatiles used as signaling compounds to attract or repel other organisms. Here, we show that volatiles of Schizophyllum commune are active against wood-decay fungi and bacteria found in its mycosphere. Read More

Complementary Roles of Wood-Inhabiting Fungi and Bacteria Facilitate Deadwood Decomposition.

mSystems 2021 Jan 12;6(1). Epub 2021 Jan 12.

Institute of Microbiology of the Czech Academy of Sciences, Prague, Czech Republic

Forests accumulate and store large amounts of carbon (C), and a substantial fraction of this stock is contained in deadwood. This transient pool is subject to decomposition by deadwood-associated organisms, and in this process it contributes to CO emissions. Although fungi and bacteria are known to colonize deadwood, little is known about the microbial processes that mediate carbon and nitrogen (N) cycling in deadwood. Read More

Bark coverage shifts assembly processes of microbial decomposer communities in dead wood.

Proc Biol Sci 2019 10 9;286(1912):20191744. Epub 2019 Oct 9.

Field Station Fabrikschleichach, Department of Animal Ecology and Tropical Biology (Zoology III), Julius-Maximilians-University Würzburg, Glashüttenstrasse 5, 96181 Rauhenebrach, Germany.

Bark protects living trees against environmental influences but may promote wood decomposition by fungi and bacteria after tree death. However, the mechanisms by which bark determines the assembly process and biodiversity of decomposers remain unknown. Therefore, we partially or completely removed bark from experimentally felled trees and tested with null modelling whether assembly processes were determined by bark coverage and if biodiversity of molecularly sampled fungi and bacteria generally benefited from increasing bark cover.
