Hidden fairy rings and males—Genetic patterns of natural Burgundy truffle (Tuber aestivum Vittad.) populations reveal new insights into its life cycle

Florian Staubli, Lea Imola, Benjamin Dauphin, Virginie Molinier, more

Environmental Microbiology > 24 > 12 > 6376 - 6391

Burgundy truffles are heterothallic ascomycetes that grow in symbiosis with trees. Despite their esteemed belowground fruitbodies, the species' complex lifecycle is still not fully understood. Here, we present the genetic patterns in three natural Burgundy truffle populations based on genotyped fruitbodies, ascospore extracts and ectomycorrhizal root tips using microsatellites and the mating‐type...

The fall of the summer truffle: Recurring hot, dry summers result in declining fruitbody production of Tuber aestivum in Central Europe

Brian S. Steidinger, Ulf Büntgen, Uli Stobbe, Willy Tegel, more

Global Change Biology > 28 > 24 > 7376 - 7390

Global warming is pushing populations outside their range of physiological tolerance. According to the environmental envelope framework, the most vulnerable populations occur near the climatic edge of their species' distributions. In contrast, populations from the climatic center of the species range should be relatively buffered against climate warming. We tested this latter prediction using a combination...

European mushroom assemblages are phylogenetically structured by temperature

Claus Bässler, Jacob Heilmann‐Clausen, Carrie Andrew, Lynne Boddy, more

Ecography > 2022 > 11 > n/a - n/a

Recent global warming affects species compositions at an unprecedented rate. To predict climate‐induced changes in species assemblages, a better understanding of the link between species occurrence and climate is needed. Macrofungal fruit body assemblages are correlated with the thermal environment at the European scale. However, it is still unknown whether macrofungal communities are also phylogenetically...

Root colonization of bait plants by indigenous arbuscular mycorrhizal fungal communities is not a suitable indicator of agricultural land-use legacy

Jan Jansa, Veronika Řezáčová, Petr Šmilauer, Hans-Rudolf Oberholzer, more

Agriculture, Ecosystems & Environment > 2016 > 231 > C > 310-319

Arbuscular mycorrhizal (AM) fungi are present in all soils and comprise an important component of soil biota with respect to plant nutrition and growth as well as soil quality. Previous research in a number of agroecosystems had documented large impacts from various management practices (e.g., tillage, fertilization, crop rotation) on the levels of host root colonization and/or composition of the...

Climate impacts on fungal community and trait dynamics

Carrie Andrew, Einar Heegaard, Rune Halvorsen, Fernando Martinez-Peña, more

Fungal Ecology > 2016 > 22 > C > 17-25

Although climate change and variability can impact fungal phenology, the effects on community composition are less understood. Additionally, climatic variability might modify trait selection in fungi, including spore size and dispersal characteristics. Compositional and trait modifications of fungal communities would have important consequences for fungal biogeography, interactions with plant communities,...

Fine-scale genetic structure of natural Tuber aestivum sites in southern Germany

Virginie Molinier, Claude Murat, Andri Baltensweiler, Ulf Büntgen, more

Mycorrhiza > 2016 > 26 > 8 > 895-907

Although the Burgundy truffle (Tuber aestivum) is an ectomycorrhizal fungus of important economic value, its subterranean life cycle and population biology are still poorly understood. Here, we determine mating type and simple sequence repeat (SSR) maternal genotypes of mapped fruiting bodies to assess their genetic structure within two naturally colonized forest sites in southern Germany. Forty-one...

Drought-induced changes in the phenology, productivity and diversity of Spanish fungi

Ulf Büntgen, Simon Egli, J. Diego Galván, Jeffrey M. Diez, more

Fungal Ecology > 2015 > 16 > Complete > 6-18

Mushrooms are amongst the most important of non-timber forest products, with growing economic value in many rural areas of the Mediterranean region. At the same time, the effects of climate variability on fungal ecology and productivity are insufficiently understood, because the belowground life cycle of fungi is mediated in many different ways and observational field surveys at the community level...

Long-term irrigation effects on Spanish holm oak growth and its black truffle symbiont

Ulf Büntgen, Simon Egli, Loic Schneider, Georg von Arx, more

Agriculture, Ecosystems and Environment > 2015 > 202 > Complete > 148-159

The Périgord black truffle is an exclusive culinary delicacy, but its Mediterranean harvests have declined, despite cultivation efforts since the 1970s. The role of long-term irrigation, symbiotic fungus-host interaction, and microbial belowground progression remain poorly understood, because generally too short experimental settings miss the necessary degree of real world complexity and reliable...

Drought resistance of Pinus sylvestris seedlings conferred by plastic root architecture rather than ectomycorrhizal colonisation

Barbara Moser, Tabea Kipfer, Sarah Richter, Simon Egli, more

Annals of Forest Science > 2015 > 72 > 3 > 303-309

Context Increased summer drought is considered as a threat to the regeneration of Pinus sylvestris in the Central Alps. To a certain degree, seedlings are able to mitigate negative effects of drought by altering root/shoot ratios. But, seedlings may also enhance access to water and nutrients by cooperation with ectomycorrhizal fungi. Aims ...

Long-term results of therapeutic local anesthesia (neural therapy) in 280 referred refractory chronic pain patients

Simon Egli, Mirjam Pfister, Sabina M. Ludin, Katia Puente de la Vega, more

BMC Complementary and Alternative Medicine > 2015 > 15 > 1 > 1-9

Background Can the application of local anesthetics (Neural Therapy, NT) alone durably improve pain symptoms in referred patients with chronic and refractory pain? If the application of local anesthetics does lead to an improvement that far exceeds the duration of action of local anesthetics, we will postulate that a vicious circle of pain in the reflex arcs has been disrupted (hypothesis). Methods...

Breaking new ground at the interface of dendroecology and mycology

Ulf Büntgen, Simon Egli

Trends in Plant Science > 2014 > 19 > 10 > 613-614

New insight on the mycorrhizal fungus–host association, expected to emerge from combining dendrochronology, wood anatomy and mycology, may help to understanding better and disentangle biotic, abiotic, and combined edaphic factors of the mutualistic relation between ectomycorrhizal fungi and their perennial partners.

Climate variation effects on fungal fruiting

Lynne Boddy, Ulf Büntgen, Simon Egli, Alan C. Gange, more

Fungal Ecology > 2014 > 10 > Complete > 20-33

Earth's climate is changing. Effects of climate change on fungal distribution and activity are hard to predict because they are mediated in many different ways, including: fungal physiology, reproduction and survival, host physiology, spatial and temporal distribution of hosts, resource availability and competition. Currently it is hard to monitor such effects on fungal mycelium in the field, but...

Rhizosphere fungal assemblages and soil enzymatic activities in a 110-years alpine chronosequence

Monika Welc, Emmanuel Frossard, Simon Egli, Else K. Bünemann, more

Soil Biology and Biochemistry > 2014 > 74 > Complete > 21-30

The abundance, distribution and functions of soil fungi in alpine ecosystems remain poorly understood. We aimed at linking the fungal community structure with soil enzymatic activities in the rhizospheres of several plants associating with mycorrhizal fungi (arbuscular, ecto- and ericoid) and growing along a soil developmental gradient on the forefield of an alpine glacier. Fungal communities in roots...
