Special Issue Information

Dear Colleagues,

Wood decay fungi are central players of forest life and carbon cycling. They are highly diversified and involved in complex biotic and abiotic interactions at all stages of wood and tree life. Their precise identification through classical approaches is made difficult by their polymorphism and small size. Some of them are also involved in human and/or animal/plant diseases, reinforcing the importance of their proper detection and control.

The capacity to have a proper diagnosis of fungi actually involved in a particular situation of interest constitute a determining factor of success of any mitigation or control attempt by physical and/or chemical treatment. It also concerns non-wood building parts since wood fungi can expand their damages beyond wood. Molecular tools enabling a precise identification of fungi from minute building air or material samples allow faster and more accurate identification but are still costly and subjected to sampling issues, especially when a diagnosis is needed for whole buildings or other civil engineering works, particularly if asymptomatic. Contributions to this Special Issue are expected to deal with those issues, particularly regarding the setup of HT DNA analysis systems at affordable cost and in combination with other predictive approaches of service life.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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. Forests 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Ganoderma resinaceum Boud. is commonly found in Mediterranean region, but rarely in Western, Central or Eastern Europe. It is a parasitic basidiomycetous fungus causing stem decay—especially in urban trees. A collection of nine fungal specimens from Slovakia (Central Europe), morphologically identified as G. resinaceum, was recently studied on the basis of sequence data from the internal transcribed spacer (ITS) regions. Analyses showed that the collections clustered into two separate groups. In this study—for the first time—the sequences of other molecular markers, namely partial translation elongation factor (tef1-α) region and partial 25S large subunit ribosomal RNA gene (25S LSU rRNA), as well as matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI–TOF MS) were obtained and used to evaluate the genetic variability of G. resinaceum. All these analyses confirm the existence of two previously unrecognized genotypes within the morphospecies. Full article

Prunus divaricata and Prunus armeniaca are important wild fruit trees that grow in part of the Western Tianshan Mountains in Central Asia, and they have been listed as endangered species in China. Shot-hole disease of stone fruits has become a major threat in the wild-fruit forest of the Western Tianshan Mountains. Twenty-five isolates were selected from diseased P. divaricata and P. armeniaca. According to the morphological characteristics of the culture, the 25 isolates were divided into eight morphological groups. Conidia were spindle-shaped, with ovate apical cells and truncated basal cells, with the majority of conidia comprising 3–4 septa, and the conidia had the same shape and color in morphological groups. Based on morphological and cultural characteristics and multilocus analysis using the internal transcribed spacer (ITS) region, partial large subunit (LSU) nuclear ribosomal RNA (nrRNA) gene, and the translation elongation factor 1-alpha (tef1) gene, the fungus was identified as Wilsonomyces carpophilus. The 25 W. carpophilus isolates had high genetic diversity in phylogenetic analysis, and the morphological groups did not correspond to phylogenetic groups. The pathogenicity of all W. carpophilus isolates was confirmed by inoculating healthy P. divaricata and P. armeniaca leaves and fruits. The pathogen was re-isolated from all inoculated tissues, thereby fulfilling Koch’s postulates. There were no significant differences in the pathogenicity of different isolates inoculated on P. armeniaca and P. divaricata leaves (p > 0.05). On fruit, G053 7m3 and G052 5m2 showed significant differences in inoculation on P. armeniaca, and G010 5m2 showed extremely significant differences with G004 7m2 and G004 5m2 on P. divaricata (p < 0.05). This is the first report on shot-hole disease of P. armeniaca (wild apricot) leaves and P. divaricata induced by W. carpophilus in China. Full article
