Special Issue Information

Dear Colleagues,

Many aspects of the biology and ecology of hypogeus ectomycorrhizal fungi, such as truffles, remain largely unknown, both in terms of their mysterious life cycle and their ecological determinants for the fructification.

Some species of the genus Tuber are renowned worldwide for their organoleptic traits, thus having a considerable economic value, and are harvested in wild forests, as well as cultivated.

Unfortunately, the natural production of truffles has actually been declining, resulting in low and uncertain yields. Satisfying explanations for this decrease in both natural and cultivated truffle yields are still lacking, even though different factors have been suggested as possible explanation for this decline, including climate change and unsustainable over-harvesting.

Despite exciting advances in several research fields, our understanding of several aspects surrounding truffle biology, ecology, preservation strategy, and cultivation management still remain limited.

In this Special Issue, articles (original research papers, reviews, and opinions) dealing with various aspects related to biological and ecological requirements underlying the production mechanisms of this economically important fungal delicacy are welcome.

The scope of this Special Issue includes, but is not limited to, the following themes:

  • Analyses of genetic diversity, spatial, and temporal distribution patterns of strains in the field and population structure (on both large and small scales);
  • Life cycle and reproductive strategy;
  • Evolution and phylogenetics analyses;
  • Truffle ecology;
  • Microbial communities interacting with truffle fungi;
  • Planning actions to protect and preserve truffle natural resources and environment;
  • Optimization of truffle cultivation management strategies;
  • Genome sequencing and RNAseq analyses.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Fungi is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The enticing aroma of truffles is a key factor for their culinary value. Although all truffle species tend to be pricy, the most intensely aromatic species are the most sought after. Research into the aroma of truffles encompasses various disciplines including chemistry, biology, and sensory science. This study focusses on the chemical composition of the aroma of black truffles (Tuber melanosporum) and the changes occurring under different storage conditions. For this, truffle samples were stored under different treatments, at different temperatures, and measured over a total storage time of 12 days. Measurements of the truffle aroma profiles were taken with SPME/GC–MS at regular intervals. To handle the ample data collected, a systematic approach utilizing multivariate data analysis techniques was taken. This approach led to a vast amount of data which we made publicly available for future exploration. Results reveal the complexity of aroma changes, with 695 compounds identified, highlighting the need for a comprehensive understanding. Principal component analyses offer initial insights into truffle composition, while individual compounds may serve as markers for age (formic acid, 1-methylpropyl ester), freshness (2-Methyl-1-propanal; 1-(methylthio)-propane), freezing (tetrahydrofuran), salt treatment (1-chloropentane), or heat exposure (4-hydroxy-3-methyl-2-butanone). This research suggests that heat treatment or salt contact significantly affects truffle aroma, while freezing and cutting have less pronounced effects in comparison. The enrichment of compounds showing significant changes during storage was investigated with a metabolomic pathway analysis. The involvement of some of the enriched compounds on the pyruvate/glycolysis and sulfur pathways was shown. Full article
