OBJECTIVE To investigate the potential of Gomphidius viscidus, a kind of ectomycorrhizal fungi, for phytoremediation of anthracene in soil. METHODS Absorptioe changes of micro-habitat were studied in detail. CONCLUSION Ectomycorrhizal plants have a strong potential for remediation of polycyclic aromatic hydrocarn characteristics of both active and inactivated mycelia. RESULTS A high calcu...

Symbiotic fungi's role in providing nitrogen to host plants is well-studied in tundra at Toolik Lake, Alaska, but little-studied in the adjoining boreal forest ecosystem. Along a 570 km north-south transect from the Yukon River to the North Slope of Alaska, the 15N content was strongly reduced in ectomycorrhizal and ericoid mycorrhizal plants including Betula, Salix, Picea mariana (P. Mill.) B....

two ectomycorrhizal fungi, Pisolithus tinctorius (Pers.) Coker and Couch and Paxillus involutus (Batsch) Fr., was studied in vitro. Spermidine was the main polyamine in the mycelium of both fungi. Paxillus involutus also produced large amounts of the diamine putrescine, whereas Pisolithus tinctorius contained traces of the diamine cadaverine and released into the culture medium an unknown compo...

To investigate functional differences in the recognition and response mechanisms of conifer roots to fungi with different trophic strategies, Pinus sylvestris L. was challenged with a saprotrophic fungus Trichoderma aureoviride Rifai. The results were compared with separate studies investigating pine interactions with a pathogen, Heterobasidion annosum (Fr.) Bref. sensu stricto and an ectomycor...

Fungal community composition often shifts in response to warmer temperatures, which might influence decomposition of recalcitrant carbon (C). We hypothesized that evolutionary trade-offs would enable recalcitrant C-using taxa to respond more positively to warming than would labile C-using taxa. Accordingly, we performed a warming experiment in an Alaskan boreal forest and examined changes in th...

Biological invasions are a rapidly increasing driver of global change, yet fundamental gaps remain in our understanding of the factors determining the success or extent of invasions. For example, although most woody plant species depend on belowground mutualists such as mycorrhizal fungi and nitrogen-fixing bacteria, the relative importance of these mutualisms in conferring invasion success is ...

Forty-se\'en different isolates of ectomycorrhizal fungi, from 16 different genera, were screened for their etfecti\eness in increasmg the growth of Eucalyptus globulus Labill. where supply of P is deficient. Plants were grown in a P-deficienI sand, in pots, in a temperature-controlled glasshouse. Seedlings were harvested 63 and 87 d after planting, and were assessed for dry matter production a...

This article is a Commentary on Hagenbo et al. (2021), 230: 1609–1622. ‘There exciting potential for coupling in-growth bag approaches with other techniques to advance our fundamental understanding of EMM dynamics.’ Compared mycorrhizas and sporocarps, which are both relatively conspicuous produced in discrete units, quantifying the standing biomass dynamics significant challenge practice becau...
