A high-affinity ammonium transporter from the mycorrhizal ascomycete Tuber borchii
Fungal Genetics and Biology, 2002An 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 ...

Characterization of the Tuber borchii nitrate reductase gene and its role in ectomycorrhizae
Molecular Genetics and Genomics, 2003The 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

Survey on the intraspecific variability of Tuber borchii Vittad
2011T. borchii is a very common truffle in Sardinia and in other Italian regions. It is a ubiquitous spedes as it can be found both in the inland hills and the coastal environment especial1y when covered by pine forests, in a wide range of variable soils from c1ayey types to the loose and sandy ones; with sub-alkaline, sub-acid and even acid reaction as in

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 ...

Mycorrhization: Tuber borchii Vittad. competitivity with respect to other species of Tuber.
2009In truffle beds planted in environments not suitable for the truffle species chosen, mychorrhizal substitution usually takes place after a period of time. The present work was aimed at verifying the capacity of mycorrhization of Tuber borchii in the presence of other Tuber species in the soil.

TAXONOMIC AND QUALITY ISSUES ASSOCIATED WITH THE COMMERCIALIZATION OF TUBER BORCHII
2010Tuber 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 ...
