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.

Sporecasting Biogeography Across Scales: Continental Patterns and Local Constraints on Macrofungal Dispersal

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Understanding how aerial fungal diversity varies across space, habitat, and disturbance is key to linking local‐scale sporocarp (fruiting body) reproduction with continental‐scale biogeography. In this study, we combined passive spore trap metabarcoding with macrofungal sporocarp records from 31 plots in eight sites across North America to ...

Transcriptional Responses of Paxillus involutus and Betula pendula During Formation of Ectomycorrhizal Root Tissue

Molecular Plant-Microbe Interactions, 2004
In order to obtain information on genes specifically expressed in the ectomycorrhizal symbiosis, 3,555 expressed sequence tags (ESTs) were analyzed from a cDNA library constructed from ectomycorrhiza formed between the basidiomycete Paxillus involutus ...

Cadmium-Responsive Thiols in the Ectomycorrhizal Fungus Paxillus involutus [PDF]

Applied and Environmental Microbiology, 2004
ABSTRACT Molecular and cellular mechanisms underlying the sustained metal tolerance of ectomycorrhizal fungi are largely unknown. Some of the main mechanisms involved in metal detoxification appear to involve the chelation of metal ions in the cytosol with thiol-containing compounds, such as glutathione, phytochelatins, or ...

Microplastic mineralization rate in Fenton reactions depends on polymer type

Journal of Environmental Quality, Volume 55, Issue 2, March/April 2026.
Abstract Despite microplastics (MPs) being highly inert pollutants, Fenton‐type reactions—using hydrogen peroxide (H2O2) and iron(II) ions (Fe2+)—may effectively initiate chain cleavage and induce mineralization. However, mineralization rates and mechanisms for different MP types at varying Fenton reagent concentrations remain unclear.

Aluminium tolerance of different Paxillus involutus Fr. strains originating from polluted and nonpolluted sites

Acta Societatis Botanicorum Poloniae, 2014
The caps of the sporocarps of P. involutus originating from the polluted site (Luboń) and from the control site in Kórnik and Puszcza Nadnotecka accumulated high amounts of aluminium and revealed symptoms of bioconcentration.

Growth response of drought-stressed Pinus sylvestris seedlings to single- and multi-species inoculation with ectomycorrhizal fungi. [PDF]

PLoS ONE, 2012
Many trees species form symbiotic associations with ectomycorrhizal (ECM) fungi, which improve nutrient and water acquisition of their host. Until now it is unclear whether the species richness of ECM fungi is beneficial for tree seedling performance, be

Amelioration of planting stress by soil amendment with a hydrogel–mycorrhiza mixture for early establishment of beech (Fagus sylvatica L.) seedlings [PDF]

, 2011
Introduction The mortality of nursery-grown beech (Fagus sylvatica L.) seedlings after out planting into the field is usually high. Objectives The goal of this study was to characterize the response of beech seedlings to planting stress and to test if ...

Orthoquinone, Cyclic, and Acyclic α‐Diketone Natural Products: From Food Applications to Pharmacotherapy

Phytochemicals in Food and Medicine, Volume 1, Issue 1, March 2026.
The orthoquinone metabolites from plants have antimicrobial, antioxidant, antiviral, cytotoxic, and anti‐inflammatory effects. ABSTRACT The structural diversity of natural products is vast and fascinating, and they have been recognized as an enormously diverse source of new lead compounds.
