comparative genomics and transcriptomics depict ericoid mycorrhizal fungi as versatile Saprotrophs and plant mutualists
New Phytologist, 2018Co-Authors: Stefania Daghino, Nicolas Cichocki, Ercole Di Martino, Gwenaelle Grelet, Alicia Clum, Kerrie Barry, Emmanuelle Morin, Annegret Kohler, Rhyan B DockterAbstract:Author(s): Martino, Elena; Morin, Emmanuelle; Grelet, Gwen-Aelle; Kuo, Alan; Kohler, Annegret; Daghino, Stefania; Barry, Kerrie W; Cichocki, Nicolas; Clum, Alicia; Dockter, Rhyan B; Hainaut, Matthieu; Kuo, Rita C; LaButti, Kurt; Lindahl, Bjorn D; Lindquist, Erika A; Lipzen, Anna; Khouja, Hassine-Radhouane; Magnuson, Jon; Murat, Claude; Ohm, Robin A; Singer, Steven W; Spatafora, Joseph W; Wang, Mei; Veneault-Fourrey, Claire; Henrissat, Bernard; Grigoriev, Igor V; Martin, Francis M; Perotto, Silvia | Abstract: Some soil fungi in the Leotiomycetes form ericoid mycorrhizal (ERM) symbioses with Ericaceae. In the harsh habitats in which they occur, ERM plant survival relies on nutrient mobilization from soil organic matter (SOM) by their fungal partners. The characterization of the fungal genetic machinery underpinning both the symbiotic lifestyle and SOM degradation is needed to understand ERM symbiosis functioning and evolution, and its impact on soil carbon (C) turnover. We sequenced the genomes of the ERM fungi Meliniomyces bicolor, M. variabilis, Oidiodendron maius and Rhizoscyphus ericae, and compared their gene repertoires with those of fungi with different lifestyles (ecto- and orchid mycorrhiza, endophytes, Saprotrophs, pathogens). We also identified fungal transcripts induced in symbiosis. The ERM fungal gene contents for polysaccharide-degrading enzymes, lipases, proteases and enzymes involved in secondary metabolism are closer to those of Saprotrophs and pathogens than to those of ectomycorrhizal symbionts. The fungal genes most highly upregulated in symbiosis are those coding for fungal and plant cell wall-degrading enzymes (CWDEs), lipases, proteases, transporters and mycorrhiza-induced small secreted proteins (MiSSPs). The ERM fungal gene repertoire reveals a capacity for a dual Saprotrophic and biotrophic lifestyle. This may reflect an incomplete transition from Saprotrophy to the mycorrhizal habit, or a versatile life strategy similar to fungal endophytes.

the plant cell wall decomposing machinery underlies the functional diversity of forest fungi
Science, 2011Co-Authors: Daniel C Eastwood, Fred O Asiegbu, Kerrie Barry, Dimitrios Floudas, Manfred Binder, Andrzej Majcherczyk, Patrick Schneider, Andrea Aerts, Scott E Baker, Mika BendiksbyAbstract:Brown rot decay removes cellulose and hemicellulose from wood?residual lignin contributing up to 30percent of forest soil carbon?and is derived from an ancestral white rot Saprotrophy in which both lignin and cellulose are decomposed. Comparative and functional genomics of the ?dry rot? fungus Serpula lacrymans, derived from forest ancestors, demonstrated that the evolution of both ectomycorrhizal biotrophy and brown rot Saprotrophy were accompanied by reductions and losses in specific protein families, suggesting adaptation to an intercellular interaction with plant tissue. Transcriptome and proteome analysis also identified differences in wood decomposition in S. lacrymans relative to the brown rot Postia placenta. Furthermore, fungal nutritional mode diversification suggests that the boreal forest biome originated via genetic coevolution of above- and below-ground biota

The Plant Cell Wall-Decomposing Machinery Underlies the Functional Diversity of Forest Fungi

Comparative and functional genomics of the "dry rot" fungus Serpula lacrymans, derived from forest ancestors, demonstrated that the evolution of both ectomycorrhizal biotrophy and brown rot Saprotrophy were accompanied by reductions and losses in specific protein families, suggesting adaptation to an intercellular interaction with plant tissue.

Contrasting effects of ectomycorrhizal fungi on early and late stage decomposition in a boreal forest
The ISME Journal, 2018Co-Authors: Erica Sterkenburg, Karina Engelbrecht Clemmensen, Roger D. Finlay, Alf Ekblad, Björn D. LindahlAbstract:Symbiotic ectomycorrhizal fungi have received increasing attention as regulators of below-ground organic matter storage. They are proposed to promote organic matter accumulation by suppressing Saprotrophs, but have also been suggested to play an active role in decomposition themselves. Here we show that exclusion of tree roots and associated ectomycorrhizal fungi in a boreal forest increased decomposition of surface litter by 11% by alleviating nitrogen limitation of Saprotrophs–a “Gadgil effect”. At the same time, root exclusion decreased Mn-peroxidase activity in the deeper mor layer by 91%. Our results show that ectomycorrhizal fungi may hamper short-term litter decomposition, but also support a crucial role of ectomycorrhizal fungi in driving long-term organic matter oxidation. These observations stress the importance of ectomycorrhizal fungi in regulation of below-ground organic matter accumulation. By different mechanisms they may either hamper or stimulate decomposition, depending upon stage of decomposition and location in the soil profile.

Modelling the influence of ectomycorrhizal decomposition on plant nutrition and soil carbon sequestration in boreal forest ecosystems
New Phytologist, 2016Co-Authors: Preetisri Baskaran, Karina Engelbrecht Clemmensen, Riitta Hyvönen, S. Linnea Berglund, Björn D. Lindahl, Göran I. Ågren, Stefano ManzoniAbstract:Summary Tree growth in boreal forests is limited by nitrogen (N) availability. Most boreal forest trees form symbiotic associations with ectomycorrhizal (ECM) fungi, which improve the uptake of inorganic N and also have the capacity to decompose soil organic matter (SOM) and to mobilize organic N (‘ECM decomposition’). To study the effects of ‘ECM decomposition’ on ecosystem carbon (C) and N balances, we performed a sensitivity analysis on a model of C and N flows between plants, SOM, Saprotrophs, ECM fungi, and inorganic N stores. The analysis indicates that C and N balances were sensitive to model parameters regulating ECM biomass and decomposition. Under low N availability, the optimal C allocation to ECM fungi, above which the symbiosis switches from mutualism to parasitism, increases with increasing relative involvement of ECM fungi in SOM decomposition. Under low N conditions, increased ECM organic N mining promotes tree growth but decreases soil C storage, leading to a negative correlation between C stores above- and below-ground. The interplay between plant production and soil C storage is sensitive to the partitioning of decomposition between ECM fungi and Saprotrophs. Better understanding of interactions between functional guilds of soil fungi may significantly improve predictions of ecosystem responses to environmental change.

ectomycorrhizal fungi potential organic matter decomposers yet not Saprotrophs
New Phytologist, 2015Co-Authors: Björn D. Lindahl, Anders TunlidAbstract:Although hypothesized for many years, the involvement of ectomycorrhizal fungi in decomposition of soil organic matter remains controversial and has not yet been fully acknowledged as an important factor in the regulation of soil carbon (C) storage. Here, we review recent findings, which support the view that some ectomycorrhizal fungi have the capacity to oxidize organic matter, either by brown-rot' Fenton chemistry or using white-rot' peroxidases. We propose that ectomycorrhizal fungi benefit from organic matter decomposition primarily through increased nitrogen mobilization rather than through release of metabolic C and question the view that ectomycorrhizal fungi may act as facultative Saprotrophs. Finally, we discuss how mycorrhizal decomposition may influence organic matter storage in soils and mediate responses of ecosystem C sequestration to environmental changes.

Translocation of 32P between interacting mycelia of a wood‐decomposing fungus and ectomycorrhizal fungi in microcosm systems
New Phytologist, 1999Co-Authors: Björn D. Lindahl, Stefan Olsson, Jan Stenlid, Roger D. FinlayAbstract:SUMMARY Interactions between Saprotrophic and ectomycorrhizal fungi have been largely ignored, although their mycelia often share the same microsites. The mycelial systems show general similarity to each other and, although the enzymatic potential of the Saprotrophic fungi is generally considered to be higher, the importance of organic nutrient sources to ectomycorrhizal fungi is now widely accepted. In the experiments described here, nutritional interactions involving transfer of elements from one mycelium to the other have been monitored dynamically using radioactive tracers and a non-destructive electronic autoradiography system. Microcosms were used in which mycelial systems of the ectomycorrhizal fungi Suillus variegatus and Paxillus involutus, extending from Pinus sylvestris host plants, were confronted with mycelia of the Saprotroph Hypholomafasciculare extending from wood blocks. The fungi showed a clear morphological confrontation response. The mycorrhizal mycelium often formed dense patches over the Hypholoma mycelia. Up to 25 % of the 32p present in the Hypholoma mycelium was captured by the mycorrhizal fungi and translocated to the plant host within 30 d. The transfer of 32p to the Saprotroph from labelled mycorrhizal mycelium was one to two orders of magnitude lower. The significance of this transfer as a 'short cut' in nutrient cycling is discussed.

New Phytologist © 2018 New Phytologist Trust Some soil fungi in the Leotiomycetes form ericoid mycorrhizal (ERM) symbioses with Ericaceae. In the harsh habitats in which they occur, ERM plant survival relies on nutrient mobilization from soil organic matter (SOM) by their fungal partners. The characterization of the fungal genetic machinery underpinning both the symbiotic lifestyle and SOM degradation is needed to understand ERM symbiosis functioning and evolution, and its impact on soil carbon (C) turnover. We sequenced the genomes of the ERM fungi Meliniomyces bicolor, M. variabilis, Oidiodendron maius and Rhizoscyphus ericae, and compared their gene repertoires with those of fungi with different lifestyles (ecto- and orchid mycorrhiza, endophytes, Saprotrophs, pathogens). We also identified fungal transcripts induced in symbiosis. The ERM fungal gene contents for polysaccharide-degrading enzymes, lipases, proteases and enzymes involved in secondary metabolism are closer to those of Saprotrophs and pathogens than to those of ectomycorrhizal symbionts. The fungal genes most highly upregulated in symbiosis are those coding for fungal and plant cell wall-degrading enzymes (CWDEs), lipases, proteases, transporters and mycorrhiza-induced small secreted proteins (MiSSPs). The ERM fungal gene repertoire reveals a capacity for a dual Saprotrophic and biotrophic lifestyle. This may reflect an incomplete transition from Saprotrophy to the mycorrhizal habit, or a versatile life strategy similar to fungal endophytes.
