Truffles have evolved from epigeous (aboveground) ancestors in nearly every major lineage of fleshy fungi. Because accelerated rates of morphological evolution accompany the transition to the truffle form, closely related epigeous ancestors remain unknown for most truffle lineages. This is the case for the quintessential truffle genus Tuber, which includes species with socio-economic importance...
BACKGROUND This work aimed at characterizing 12 isolates of the genus Tuber including Tuber melanosporum (11 isolates) and Tuber brumale (one isolate). This was done using internal transcribed spacer (ITS) sequences, confirming their origin. RESULTS Analysis of their mating type revealed that both MAT1-1 and MAT1-2 exist within these isolates (with 3 and 8 of each, respectively). We observed ...
Elaphomyces ('deer truffles') is one of the most important ectomycorrhizal fungal genera in temperate and subarctic forest ecosystems, but also one of the least documented in public databases. The current systematics are mainly based on macromorphology, and is not significantly different from that proposed by Vittadini (1831). Within the 49 species recognised worldwide, 23 were originally descr...
BACKGROUND False truffles are ecologically important as mycorrhizal partners of trees and evolutionarily highly interesting as the result of a shift from epigeous mushroom-like to underground fruiting bodies. Since its first description by Vittadini in 1831, inappropriate species concepts in the highly diverse false truffle genus Hymenogaster has led to continued confusion, caused by a large va...
Divergence of breeding system plays an important role in fungal speciation. Ectomycorrhizal fungi, however, pose a challenge for the study of reproductive biology because most cannot be mated under laboratory conditions. To overcome this barrier, we sequenced the draft genomes of the ectomycorrhizal sister species Rhizopogon vinicolor Smith and Zeller and R. vesiculosus Smith and Zeller (Basidi...
The order Phallales ( Basidiomycota ) is represented by gasteroid fungi with expanded and sequestrate basidiomata, known as stinkhorns false truffles. In phalloids, the first DNA sequence was published in 1997, after that, some studies aimed to resolve phylogenetic conflicts propose new species based on markers; however, number of families genera still generates controversies among researchers....
Multi-gene phylogenetic analyses were conducted to address the evolution of Clavicipitaceae (Ascomycota). Data are presented here for approximately 5900 base pairs from portions of seven loci: the nuclear ribosomal small and large subunit DNA (nrSSU and nrLSU), beta-tubulin, elongation factor 1alpha (EF-1alpha), the largest and second largest subunits of RNA polymerase II (RPB1 and RPB2), and m...
