The genetic structure of populations of the ectomycorrhizal basidiomycete Suillus luteus in heavy metal polluted and nonpolluted areas was studied. Sporocarps were collected at nine different locations and genotyped at four microsatellite loci. Six of the sampling sites were severely contaminated with heavy metals and were dominated by heavy metal‐tolerant individuals. Considerable genetic diversity was found within the geographical subpopulations, but no reduction of the genetic diversity… 

Genetic diversity and population structure of Chinese Lentinula edodes revealed by InDel and SSR markers

This was the first study on the Genetic structure and differentiation between populations, as well as the relationship between genetic structure and phenotypic traits in L. edodes, which suggested Geographic distribution could play a vital role in the formation of the observed population structure.

Incipient local adaptation in a fungus: evolution of heavy metal tolerance through allelic and copy-number variation

Genome scans across individuals from recently polluted and nearby unpolluted soils in Belgium revealed no evidence of population structure but detected allelic divergence and gene copy number variation in genes involved in metal exclusion, storage, immobilization, and reactive oxygen species detoxification.

Specific regions in the Sod1 locus of the ericoid mycorrhizal fungus Oidiodendron maius from metal-enriched soils show a different sequence polymorphism.

To investigate within-species gene divergence in stressful environments, sequence polymorphism of a neutral and a functional gene in O. maius isolates derived from the serpentine site, from a site heavily polluted with industrial wastes and from unpolluted sites were compared.

Population Biology and Ecology of Ectomycorrhizal Fungi

Investigation through the prism of landscape genetics and demographic reconstruction helped deciphering ancient and modern environmental drivers of population diversity, indicating the value of EcMF for testing biogeographic hypotheses.

Genetic Population Structure of the Ground Beetle, Pterostichus oblongopunctatus, Inhabiting a Fragmented and Polluted Landscape: Evidence for Sex-Biased Dispersal

This investigation of population genetic structure indicated, for the first time, male-biased dispersal in carabid beetles and demonstrated the application of microsatellite markers to answer questions regarding complex interactions between population structure and physical properties of the landscape.

Understanding introduction history: Genetic structure and diversity of the edible ectomycorrhizal fungus, Suillus luteus, in Patagonia (Argentina)

The results suggest that the weak genetic structure of the species reflects the short time that has elapsed since the introduction of S. luteus into Patagonia, and its expansion with exotic afforestation there, and is probably related to the anthropogenic movement of inoculum associated with forestry practices.

Little to no genetic structure in the ectomycorrhizal basidiomycete Suillus spraguei (Syn. S. pictus) across parts of the northeastern USA

The population genetic structure of the ectomycorrhizal basidiomycete Suillus spraguei over distances up to 600 km in northeastern USA forests is determined and supports the presence of a single cluster.

Fungal heavy metal adaptation through single nucleotide polymorphisms and copy‐number variation

Adaptation in the mycorrhizal fungus Suillus luteus driven by soil heavy metal contamination is document and contribute to understanding the processes underlying local adaptation under strong environmental selection.



AFLP-based assessment of the effects of environmental heavy metal pollution on the genetic structure of pioneer populations of Suillus luteus.

Overall, the genetic differentiation between subpopulations was low, but Bayesian inference indicated the presence of two genetically differentiated clusters of individuals, which may correspond to different intercompatibility groups in S. luteus.

Genetic variation and heavy metal tolerance in the ectomycorrhizal basidiomycete Suillus luteus

The in vitro Zn and Cd tolerance of the S. luteus isolates from the polluted habitat were significantly higher than the tolerances measured in the isolate from the nonpolluted site, suggesting that the elevated soil metal concentrations might be responsible for the evolution of adaptive Zn-Cd tolerance.

Genetic variation between and within populations of a perennial grass: Arrhenatherum elatius

Using morphological characters as well as allozyme markers, the genetic diversity in populations on toxic soils (mining spoil) was found to be higher than in populations in normal pasture, suggesting that the tolerant populations have been built up from a large number of tolerant genotypes emanating from normal pasture populations in which tolerance genes are not uncommon.

On the evolution of heavy‐metal tolerant populations in Armeria maritima: evidence from allozyme variation and reproductive barriers

The pattern of reproductive isolation among populations suggests that evolution of heavy‐metal tolerant populations has not triggered the development of reproductive barriers against non‐tolerant populations, however, partial reproductive isolation has occurred under geographic separation.

Evolutionary adaptation to Zn toxicity in populations of Suilloid fungi

The severe Zn pollution in the surroundings of the Zn smelters has clearly triggered the evolution of an increased Zn tolerance in the pioneer Suilloid fungi, and the frequency of Zn-tolerant genotypes decreases.

Genetics of mine invasions by Deschampsia cespitosa (Poaceae)

Isozyme variation in populations from contaminated and uncontaminated sites were compared to investigate the genetic consequences of mine invasion and find out whether diploid or tetraploid populations are more vulnerable to mine invasion.

Genetic diversity and heavy metal tolerance in populations of Silene paradoxa L. (Caryophyllaceae): a random amplified polymorphic DNA analysis

Eight populations of Silene paradoxa L. (Caryophyllaceae) growing in copper mine deposits, in serpentine outcrops or in noncontaminated soil in central Italy, were analysed using random amplified polymorphic DNA (RAPD) markers to investigate the pattern of genetic variation.

Genetic and Phylogeographic Structures of the Symbiotic Fungus Tuber magnatum

This study is the first to identify a genetic and phylogeographic structure in T. magnatum, and found that the southernmost and the northwesternmost populations were significantly differentiated from the rest of the populations.

The potential for evolution of heavy metal tolerance in plants

A series of grasslands of different ages which have suffered copper pollution for different lengths of time have been used to follow the evolution of metal tolerance, showing that the tolerant populations consist of a large number of different individual clones or genotypes.

Patterns of vegetative growth and gene flow in Rhizopogon vinicolor and R. vesiculosus (Boletales, Basidiomycota)

It is demonstrated that isolation by distance does not occur in either species at the intraplot sampling scale and that clonal propagation (vegetative growth) is significantly more prevalent in R. vesiculosus than inR.
