Assessing genetic variation within populations and genetic exchange between populations requires an understanding of the distribution and abundance of individual genotypes within the population. Previous workers have used somatic incompatibility testing to distinguish clones or individuals in natural populations of ectomycorrhizal fungi. However, somatic incompatibility tests performed with isolates of Suillus granulatus from a natural population revealed a lack of transitiveness, which brought…

Comparison of RAPD technique and somatic incompatibility tests for the identification of Phlebiopsis gigantea strains
Both methods allowed us to clearly demonstrate the presence of inoculated strains 1 year after treatment and provides a valuable tool for discriminating between different P. gigantea strains and conducting epidemiological studies.
Assessment of the genetic variation among Suillus granulatus populations in Israel
Conspicuous genetic differentiation between the two S. granulatus groups indicates that there was no extensive gene flow, and the spread of alleles within or between populations might be by repeats of short- distance spore dispersal rather than by long-distance spore disperseal.
Genetic Structure within Septobasidium Colonies Suggests Outcrossing and Frequent Non Self-Fusion
Genotyping of multiple tissue isolates demonstrated that individual Septobasidium colonies were composed of a single heterozygous dikaryotic mycelium, with colonies maintaining their genetic identity despite frequent non self-fusions.
Isozyme variation and somatic incompatibility in populations of the ectomycorrhizal fungus Suillus collinitus
This study showed a high correlation between the results of electrophoretic isozyme analysis and those of somatic incompatibility reactions, which indicated high intraspecific variation between isolates from the same location and from different locations.
Genomic Fingerprinting of Ectomycorrhizal Fungi by Microsatellite-Primed PCR
Random amplification of polymorphic DNA (RAPD) has been used for the analysis of populations of Suillus granulatus and Laccaria bicolor and has been reported to be very sensitive to experimental variables.
Genetic structure of a natural population of the ectomycorrhizal fungus Suillus pungens
The combination of extensive vegetative growth and abundant fruiting suggests S. pungens utilizes more carbon than might be expected for a species which accounts for <3% of the total ectomycorrhizal abundance at the site, and genetic analysis shows that although out-crossing appears to predominate in the population, at least a low percentage of spores are secondarily homothallic.
Genetic variation within and among populations of Fomitopsis pinicola (Basidiomycetes)
RAPD polymorphisms used to reveal the genetic population structure of Fomitopsis pinicola from 5 populations in southwestern Sweden with outliers in Finland and Norway revealed that multiple infections were present in a single tree and that the fungus probably infects host-trees by basidiospores, arriving via the air.
Characterization of Cryphonectria parasitica strains by random amplified polymorphic DNA (RAPD) technique and conventional methods
RAPD analysis proved to be an efficient method for distinguishing between different C. parasitica genotypes, and small dsRNA fragments were found in two Austrian strains that exhibited reduced virulence.


The fungus Armillaria bulbosa is among the largest and oldest living organisms
A means by which individual fungi can be unambiguously identified within local populations is reported and an individual of Armillaria bulbosa is identified that occupies a minimum of 15 hectares, weighs in excess of 10,000kg, and has remained genetically stable for more than 1,500 years.
