Burgundy truffles (Tuber aestivum syn. Tuber uncinatum) are the highly prized fruit bodies of subterranean fungi always occurring in ectomycorrhizal symbiosis with host plants. Successful cultivation can be achieved through artificial mycorrhization and outplanting of mostly oaks and hazel on suitable terrain. Here, we review ecological requirements, the influence of environmental factors, and the importance of molecular techniques for a successful cultivation of T. aestivum across Europe. The historical background and current knowledge of T. aestivum cultivation are discussed in light of its socioeconomic relevance.

“…Tuber indicum is also a black truffle species that is phylogenetically and morphologically close or similar to T. melanosporum , and it is one of the major commercial truffles in China (Zhang et al, 2019). In addition to T. indicum, Tuber sinoaestivum , and Tuber pseudoexcavatum are all Chinese black truffles with commercial value, and they have been exported to Europe, the United States, and Australia, although they do not command a price as high as T. melanosporum (García-Montero et al, 2010; Zambonelli, 2012; Ye et al, 2018). Also, the investigations about the T. sinoaestivum and T. pseudoexcavatum were relatively rare compared with T. melanosporum and T. indicum.…”

Truffles are ascomycetous ectomycorrhizal fungi that have elevated status in the culinary field due to their unique aroma and taste as well as their nutritional value and potential biological activities. Tuber melanosporum, T. indicum, T. panzhihuanense, T. sinoaestivum, and T. pseudoexcavatum are five commercial truffle species mainly distributed in Europe or China. In this study, an untargeted metabolomics technology based on an ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was applied to analyze the metabolic profiles and variations among these five truffle species. In our results, a total of 2376 metabolites were identified under positive ion mode, of which 1282 had significantly differential amounts and covered 110 pathways or metabolisms. Principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA) revealed a clear separation from each of these five truffles, indicating a significantly different metabolic profile among them, with the biggest difference between T. melanosporum and the other four truffles. The differential metabolites covered various chemical categories, and a detailed analysis was performed for nine metabolic categories, including amino acids, saccharides and nucleosides, organic acids, alkaloids, flavonoids, carnitines, phenols and alcohols, esters, and sulfur compounds. For each of the nine categories, most of metabolites predominantly accumulated in T. melanosporum compared with the other four truffles. Meanwhile, there were significant differences of the average ion intensity in each category among the five truffles, e.g., higher amounts of amino acids was detected in T. panzhihuanense and T. pseudoexcavatum; T. indicum contained significantly more carnitines, while there were more alkaloids in T. melanosporum. Additionally, some metabolites with biological activities were discussed for each category, such as acetyl-L-carnitine, adenine, neobavaisoflavone, and anandamide. Generally, this study may provide the valuable information regarding the variation of the metabolic composition of these five commercial truffle species, and the biological significance of these metabolites was uncovered to explore the metabolic mechanisms of truffles, which would be helpful for further research on the compounds and potential biological functions in truffles that have not yet been investigated.

“…Chen et al (2005) and Song et al (2005) also noticed these differences but failed to use them for specific discrimination. European mycologists also noted the more globose spores in the Chinese T. sinoaestivum, but regarded it as a separate taxon (Zambonelli et al 2012). Although T. aestivum is regarded as a widespread species with high morphological variation, the differences in T. sinoaestivum exceed the variation accepted for T. aestivum.…”

A new Tuber species, T. sinoaestivum, is described from southwestern China based on morphological and molecular analyses. The new species, which was found fruiting in association with Pinus armandii, has been previously misidentified as T. aestivum (=T. uncinatum). Although morphologically quite similar, T. sinoaestivum differs from the European species by more globose ascospores ornamented with a shallower reticulum. ITS sequence analyses show only 92% similarity between the two species, further supporting the taxonomic separation of T. sinoaestivum from T. aestivum.
