Global Patterns of Gene Regulation Associated with the Development of Ectomycorrhiza Between Birch (Betula pendula Roth.) and Paxillus involutus (Batsch) Fr.

Molecular Plant-Microbe Interactions, 2005
The formation of ectomycorrhizal (ECM) root tissue is characterized by distinct morphological and developmental stages, such as preinfection and adhesion, mantle, and Hartig net formation.

Coumarin-pi, a new antioxidant coumarin derivative from Paxillus involutus

Natural Product Research, 2019
Chemical investigation of Paxillus involutus lead to the isolation of a new coumarin derivative coumarin-pi (1), and three known compounds (2-4). The structure of the new compound was elucidated by interpretation of 1D and 2D NMR data.

The Paxillus involutus (Boletales, Paxillaceae) complex in Europe: genetic diversity and morphological description of the new species Paxillus cuprinus, typification of P. involutus s.s., and synthesis of species boundaries. [PDF]

Fungal Biology, 2014
Paxillus involutus is a model species for ecological or physiological studies of ectomycorrhizal agaricomycetes. Three to six groups or species linked to it have been ecologically and morphologically distinguished.

Selected elements of Poison Pax Paxillus involutus [PDF]

Journal of Environmental Science and Health, Part A, 2007
Concentrations of Ag, Al, Ba, Ca, Cd, Co, Cu, Cr, Cs, Fe, Ga, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Rb, Se, Sb, Sr, V, Tl and Zn have been determined in the whole fruiting bodies as well as separately in caps and stalks of Poison Pax collected from three geographically distant sites across Poland. The elements were determined using ICP-MS, ICP-OES, HG-AAS and

Rock-eating mycorrhizas: their role in plant nutrition and biogeochemical cycles [PDF]

, 2014
A decade ago, tunnels inside mineral grains were found that were likely formed by hyphae of ectomycorrhizal (EcM) fungi. This observation implied that EcM fungi can dissolve mineral grains. The observation raised several questions on the ecology of these

Current 137Cs accumulation by mushrooms in different site types of scots pine forests of Ukrainian Polissia [PDF]

Ядерна фізика та енергетика, 2023
The study of 137Cs radioactive contamination of fruiting bodies of mushrooms was carried out in September - October 2022 in 18 sampling sites laid out in the Korosten district of Zhytomyr region in 3 of the most widespread forest site types (FST): fresh ...

Fungal taste for minerals: the ectomycorrhizal fungus Paxillus involutus triggers specific genes when extracting potassium from different silicates

bioRxiv, 2021
Silicates make up about 90% of the Earth’s crust and constitute the main source of mineral nutrients for microorganisms and plants. Fungi can actively weather silicates to extract nutrients. However, it is unclear whether they are able to obtain the same

Ammonium and methylamine transport by the ectomycorrhizal fungus Paxillus involutus and ectomycorrhizas [PDF]

FEMS Microbiology Ecology, 1999
Using [(14)C]methylamine as an analogue of ammonium, the kinetics and the energetics of NH(4)(+) transport were studied in the ectomycorrhizal fungus, Paxillus involutus (Batsch) Fr. The apparent half-saturation constant (K(m)) and the maximum uptake rate (V(max)) for the carrier-mediated transport derived from the Eadie-Hofstee transformation were 180

Ecological Half-Life of ¹³⁷Cs in Fungi

Ecologies, 2022
The ecological half-life of 137Cs was calculated individually for four symbiotrophic fungi species (Boletus edulis, Imleria badia, Suillus luteus, Paxillus involutus) at 10 sampling sites in the Chornobyl exclusion zone and in the Kyiv region.

Transcriptomic responses to cadmium in the ectomycorrhizal fungus Paxillus involutus [PDF]

FEBS Letters, 2004
The molecular mechanisms underlying the response of ectomycorrhizal fungi to heavy metals in general and cadmium in particular remain poorly understood. We screened 2040 arrayed cDNAs of the ectomycorrhizal fungus Paxillus involutus to identify cadmium‐responsive genes by using differential hybridization.
