Périgord black truffle genome uncovers evolutionary origins and mechanisms of symbiosis
The sequence of the haploid genome of T. melanosporum is reported, which at ∼125 megabases is the largest and most complex fungal genome sequenced so far and results from a proliferation of transposable elements accounting for ∼58% of the genome.
Historical Biogeography and Diversification of Truffles in the Tuberaceae and Their Newly Identified Southern Hemisphere Sister Lineage
A global sampling of the Tuberaceae based on DNA sequence data from four loci suggests that Tuber evolved from an epigeous ancestor, and a well-resolvedTuberaceae phylogeny shows high levels of regional and continental endemism.
Effects of Essential Oils on Phytopathogenic Fungi In Vitro
The essential oils of Thymus vulgaris L., of Lavandula R.C. hybrid and Mentha piperita L. were tested in vitro against the pathogenic fungi and SEM observations revealed that these oils cause degeneration of the fungal hyphae which appeared emptied of their cytoplasmic content.
Occurrence and diversity of bacterial communities in Tuber magnatum during truffle maturation.
Molecular approaches made it possible to identify alpha-Proteobacteria as major constituents of a bacterial component associated with T. magnatum ascoma, independently from the degree of maturation.
Molecular phylogeny of truffles (Pezizales: Terfeziaceae, Tuberaceae) derived from nuclear rDNA sequence analysis.
Distinct episodes of fruit body morphology shifts are discernable in the 18S rDNA phylogenetic tree and the shift from an epigeous to a hypogeous form is the most parsimonious interpretation of character transformation, without any instance of character reversal.
Determination of specific volatile organic compounds synthesised during Tuber borchii fruit body development by solid-phase microextraction and gas chromatography/mass spectrometry.
The production of aromadendrene in the completely unripe fruit body suggests the existence of communication events in the early stage of ascomata formation between the fungus and the host plant, and their possible biological roles are discussed.
The ectomycorrhizal community in natural Tuber borchii grounds.
It is suggested that the presence of young oaks contributed to the maintenance of T. borchii colonization on pines, and species composition was markedly affected by the host plant, although community structure and composition was also influenced by the location from which the soil cores were collected.
