Convergent losses of decay mechanisms and rapid turnover of symbiosis genes in mycorrhizal mutualists
To elucidate the genetic bases of mycorrhizal lifestyle evolution, we sequenced new fungal genomes, including 13 ectomycorrhizal (ECM), orchid (ORM) and ericoid (ERM) species, and five saprotrophs,Expand

Engineered endophytic bacteria improve phytoremediation of water-soluble, volatile, organic pollutants
Phytoremediation of highly water soluble and volatile organic xenobiotics is often inefficient because plants do not completely degrade these compounds through their rhizospheres. This results inExpand

The cellular redox state as a modulator in cadmium and copper responses in Arabidopsis thaliana seedlings.
The cellular redox state is an important determinant of metal phytotoxicity. In this study we investigated the influence of cadmium (Cd) and copper (Cu) stress on the cellular redox balance inExpand

An inter-laboratory study to test the ability of amendments to reduce the availability of Cd, Pb, and Zn in situ.
An international inter-laboratory research program investigated the effectiveness of in situ remediation of soils contaminated by cadmium, lead and zinc, measuring changes in soil and soil solutionExpand

Nitrogen availability and colonization by mycorrhizal fungi correlate with nitrogen isotope patterns in plants
Summary • Nitrogen isotope (δ 15 N) patterns in plants may provide insight into plant N dynamics. Here, two analytical models of N-isotope cycling in plants and mycorrhizal fungi were tested, asExpand

Solubilization of toxic metal minerals and metal tolerance of mycorrhizal fungi
Abstract This work investigates the ability of ericoid mycorrhizal (ErM) and ectomycorrhizal (EcM) fungi to solubilize different toxic metal (Cd, Cu, Pb, Zn)-containing minerals. Minerals wereExpand

Differential responses of ectomycorrhizal fungi to heavy metals in vitro
Thirty-nine ectomycorrhizal isolates of Paxillus involutus, Pisolithus tinctorius, Suillus bovinus, S. luteus and S. variegatus were tested on cadmium, copper, nickel and zinc amended media toExpand

Genetic variation and heavy metal tolerance in the ectomycorrhizal basidiomycete Suillus luteus
Twenty-one isolates of the ectomycorrhizal fungus Suillus luteus were screened for their tolerance to the heavy metals Zn, Cd, Cu and Ni, measured as inhibition of radial growth and biomassExpand

The growth of the extramatrical mycelium of ectomycorrhizal fungi and the growth response of Pinus sylvestris L.
SUMMARY Nine ectomycorrhizal fungi have been studied for their effect on the growth of Pinus sylvestris L. seedlings. The plants were kept growing for six months in root chambers with a changeableExpand

Copper-Adapted Suillus luteus, a Symbiotic Solution for Pines Colonizing Cu Mine Spoils
ABSTRACT Natural populations thriving in heavy-metal-contaminated ecosystems are often subjected to selective pressures for increased resistance to toxic metals. In the present study we describe aExpand
