The carbon starvation response of the ectomycorrhizal fungus Paxillus involutus. [PDF]

FEMS Microbiol Ecol, 2015
The amounts of carbon allocated to the fungal partner in ectomycorrhizal associations can vary substantially depending on the plant growth and the soil nutrient conditions, and the fungus may frequently be confronted with limitations in carbon.

Cadmium-responsive thiols in the ectomycorrhizal fungus Paxillus involutus. [PDF]

Appl Environ Microbiol, 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 ...

Paxillus involutus-Facilitated Cd²⁺ Influx through Plasma Membrane Ca²⁺-Permeable Channels Is Stimulated by H₂O₂ and H⁺-ATPase in Ectomycorrhizal Populus × canescens under Cadmium Stress. [PDF]

Front Plant Sci, 2016
Using a Non-invasive Micro-test Technique, flux profiles of Cd2+, Ca2+, and H+ were investigated in axenically grown cultures of two strains of Paxillus involutus (MAJ and NAU), ectomycorrhizae formed by these fungi with the woody Cd2+-hyperaccumulator ...

Comparative mitogenome analysis of two ectomycorrhizal fungi (Paxillus) reveals gene rearrangement, intron dynamics, and phylogeny of basidiomycetes [PDF]

IMA Fungus, 2020
In this study, the mitogenomes of two Paxillus species were assembled, annotated and compared. The two mitogenomes of Paxillus involutus and P. rubicundulus comprised circular DNA molecules, with the size of 39,109 bp and 41,061 bp, respectively ...

Diversity and Host Relationships of the Mycoparasite Sepedonium (Hypocreales, Ascomycota) in Temperate Central Chile [PDF]

Microorganisms, 2021
We present the first major survey of regional diversity, distribution and host-association of Sepedonium. Whereas the rather scarce worldwide records of this mycoparasitic fungus suggested no specific distribution pattern of most species before, we ...

Phenolic compounds in ectomycorrhizal interaction of lignin modified silver birch [PDF]

BMC Plant Biology, 2009
Background The monolignol biosynthetic pathway interconnects with the biosynthesis of other secondary phenolic metabolites, such as cinnamic acid derivatives, flavonoids and condensed tannins.

Fatal Immunohaemolysis after the Consumption of the Poison Pax Mushroom: A Focus on the Diagnosis of the Paxillus Syndrome with the Aid of Two Case Reports [PDF]

Diagnostics, 2019
This retrospective report focuses on the diagnosis of the Paxillus syndrome, based on two fatal cases of haemolysis following the consumption of Paxillus involutus. These mushrooms are still consumed regularly, despite earlier reports of life-threatening

The ectomycorrhizal fungus Paxillus involutus converts organic matter in plant litter using a trimmed brown-rot mechanism involving Fenton chemistry. [PDF]

Environ Microbiol, 2012
Soils in boreal forests contain large stocks of carbon. Plants are the main source of this carbon through tissue residues and root exudates. A major part of the exudates are allocated to symbiotic ectomycorrhizal fungi.

Inoculation with Paxillus involutus enhances lead translocation from the roots to the aerial tissues by promoting pectin degradation in the roots of Populus ×canescens

Industrial Crops and Products
Paxillus involutus (Batsch) Fr. inoculation can improve Pb translocation from the roots to the aboveground tissues of poplars, but the underlying mechanisms remain unknown. In this study, we inoculated Populus ×canescens with or without Pa. involutus and

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 ...
