Metabolism of [15N]Alanine in the Ectomycorrhizal Fungus Paxillus involutus
Experimental Mycology, 1995Alanine metabolism in the ectomycorrhizal fungus Paxillus involutus was investigated using [N-15]alanine. Short-term exposure of mycelial discs to [N-15]alanine showed that the greatest flow of N-15 was to glutamate and to aspartate. Levels of enrichment were as high as 15-20% for glutamate and 13-18% for aspartate, whereas that of alanine reached 30%.

Multiple gene genealogies and species recognition in the ectomycorrhizal fungus Paxillus involutus
Mycological Research, 2008Paxillus involutus (basidiomycetes, Boletales) is a common ectomycorrhizal fungus in the Northern Hemisphere. The fungus displays significant variation in phenotypic characters related to morphology, physiology, and ecology. Previous studies have shown that P. involutus contains several intersterility groups and morphological species. In this study, we

The effect of Paxillus involutus Fr. on aluminum sensitivity of Norway spruce seedlings
Tree Physiology, 1993Non-mycorrhizal Norway spruce seedlings (Picea abies Karst.) and Norway spruce seedlings colonized with Paxillus involutus Fr. were grown in an axenic silica sand culture system. After successful mycorrhizal colonization, the seedlings were exposed to 200 or 800 micro M AlCl(3) for 10 weeks.

Genetic transformation of the ectomycorrhizal fungus Paxillus involutus by particle bombardment
Mycological Research, 1995Paxillus involutus was transformed using gold particle mediated gene transfer. Transformation was determined using the hygromycin B phosphotransferase gene (hph) as the selectable marker and the β-glucuronidase gene (GUS) as a reporter gene. Southern blot analysis confirmed that the vector DNA for both hph and GUS genes was integrated into the fungal ...

Mycorrhizal formation by Paxillus involutus strains in relation to their IAA‐synthesizing activity
New Phytologist, 1997summaryIAA production by the ectomycorrhizal fungus Paxillus invotutus grown in pure culture was investigated by testing IAA accumulation or IAA‐synthesizing activity. All the Paxillus involutus strains studied released indole compounds either when incubated with 0.5 mM tryptophan or in its absence.

Factors affecting amino acid uptake by the ectomycorrhizal fungus Paxillus involutus
Mycological Research, 1995Factors affecting amino acid uptake by the ectomycorrhizal fungus Paxillus involutus were investigated using tracer kinetic experiments. Amino acid uptake by P. involutus was dependent on the pH of the incubation medium. Uptake of L-glutamate and L-glutamine had a distinct pH optimum around pH 4.0 and declined sharply between pH 4.5 and 6.4.

[Poisoning with the brown roll-rim mushroom, Paxillus involutus].
Ugeskrift for laeger, 1991Brown Roll-Rim (Paxillus involutus) is a dangerous poisonous mushroom with symptoms of poisoning which occur a few hours after consumption. Repeated consumption may cause sensitization to a heat-stable toxin, resulting in haemolysis which may be of all degrees. In addition, severe gastrointestinal symptoms may be due to a heat-instable toxin.
