TAXONOMIC AND QUALITY ISSUES ASSOCIATED WITH THE COMMERCIALIZATION OF TUBER BORCHII

, 2010
Tuber borchii Vittad., commonly called bianchetto (whitish truffle), is an edible truffle with excellent culinary qualities. However, bianchetto is often regarded as one of the lesser truffles because it is often sold mixed with morphologically similar species in the Puberulum clade (Jeandroz et al., 2008) such as Tuber maculatum Vittad., Tuber ...

Strain differences in the mycelium of the ectomycorrhizal Tuber borchii

Mycological Research, 1999
Four strains of Tuber borchii were grown in liquid medium containing glucose. Evaluation of growth patterns revealed a trend of exponential growth for only one strain. Subsequently, enzyme levels were assayed and polypeptide and mRNA electrophoretic profiles were analyzed. Although the four strains were found to have many properties in common such as

SPECIFIC PRIMERS FOR RAPID TYPING OF TUBER BORCHII MYCORRHIZAL ROOTS

Acta Horticulturae, 1998
Truffles are Ascomycetous fungi that need to form a symbiotic association (mycorrhiza) with the roots of a host plant to be able to produce their fruitbodies. Many of the morphological characters used to identify a truffle fruitbody, however, are lost during this phase. DNA analyses have therefore been devised for the typing of truffle species.

The volatile organic compounds from the mycelium of Tuber borchii Vitt.

Phytochemistry, 2000
The mycelium of T. borchii (characterized by DNA analysis) grown in sterile liquid medium produced some VOCs. The VOCs were retained on carbographs by passing a flow of helium, isolated and characterized in a GC-MS equipment after a thermal desorption.

Molecular characterisation of the small GTPase CDC42 in the ectomycorrhizal fungus Tuber borchii Vittad.

Protoplasma, 2007
The small GTPase CDC42 is ubiquitously expressed in eukaryotes, where it participates in the regulation of the cytoskeleton and a wide range of cellular processes, including cytokinesis, gene expression, cell cycle progression, apoptosis, and ...

A high-affinity ammonium transporter from the mycorrhizal ascomycete Tuber borchii

Fungal Genetics and Biology, 2002
An ammonium transporter cDNA, named TbAMT1, was isolated from the ectomycorrhizal ascomycetous truffle Tuber borchii. The polypeptide encoded by TbAMT1 (52 kDa) functionally complements ammonium uptake-defective yeast mutants and shares sequence similarity with previously characterized ammonium transporters from Saccharomyces (Mep) and Arabidopsis ...

The ectomycorrhizal community in an experimental Tuber borchii truffiére

2004
The community of ectomycorrhizal fungi (ECF) in a Pinus pinea- Tuber borchii truffière was studied using both morphological and molecular methods. The abundance of types of ectomycorrhizae and the presence of sporocarps of ECF have been studied for 13 years. The occurrence of T. borchii mycorrhizae and ascocarps was compared. Six different morphotypes

Characterization of the Tuber borchii nitrate reductase gene and its role in ectomycorrhizae

Molecular Genetics and Genomics, 2003
The nitrate assimilation pathway represents a useful model system in which to study the contribution of a mycorrhizal fungus to the nitrogen nutrition of its host plant. In the present work we cloned and characterized the nitrate reductase gene (tbnr1) from Tuber borchii. The coding region of tbnr1 is 2,787 nt in length, and it encodes a protein of 929

Morphological and molecular modifications induced by different carbohydrate sources in Tuber borchii.

Journal of molecular microbiology and biotechnology, 2010
During the life cycle of mycorrhizal fungi, morphological, genetic and metabolic modifications are induced in the fungus and its symbiotic partner. These changes are influenced by environmental factors: light, gravity, oxygen, temperature, soil type, nutrients, root exudates and the presence of particular bacterial and perhaps fungal and viral ...
