Special Issue Information

Dear Colleagues,

Mycorrhizal fungi are a group of microorganisms that form a symbiotic relationship with plant roots. By interacting with their host plants, they form a mutually beneficial association. This symbiotic relationship plays a vital role in plant nutrient uptake, growth and development, and stress resistance. Mycorrhizal fungi are ubiquitous widespread soil microorganisms that include arbuscular mycorrhizal, ectomycorrhizal, ericoid mycorrhizal and orchid mycorrhizal fungi, among others. These microbes have been proven to offer an array of advantages to host plants, e.g., improving crops' nutrient status and enhancing their fitness, quality and yield. In recent years, research on mycorrhizal fungi has continued to expand, and the fields implicated have become increasingly diverse.

This Special Issue aims to gather the latest research results and theoretical advances with regard to mycorrhizal fungi, and to promote academic exchange and collaboration. We welcome papers that address the following topics:

  • Interaction of all types of mycorrhizal fungi with plants;
  • The role of mycorrhizal fungi in plant nutrient uptake and growth regulation;
  • The function of mycorrhizal fungi in ecosystems
  • The use of mycorrhizal fungi in environmental restoration and sustainable agricultural/forestry development.

This Special Issue of Microorganisms plans to collect recent research on mycorrhizal fungi. Original research articles and comprehensive reviews are welcome.

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. Microorganisms 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 2700 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.

Avocado is one of the most in-demand fruits worldwide and the trend towards its sustainable production, regulated by international standards, is increasing. One of the most economically important diseases is root rot, caused by Phythopthora cinnamomi. Regarding this problem, antagonistic microorganism use is an interesting alternative due to their phytopathogen control efficiency. Therefore, the interaction of arbuscular mycorrhizal fungi of the phylum Glomeromycota, native to the Peruvian coast (GWI) and jungle (GFI), and avocado rhizospheric bacteria, Bacillus subtilis and Pseudomonas putida, was evaluated in terms of their biocontrol capacity against P. cinnamomi in the “Zutano” variety of avocado plants. The results showed that the GWI and Bacillus subtilis combination increased the root exploration surface by 466.36%. P. putida increased aerial biomass by 360.44% and B. subtilis increased root biomass by 433.85%. Likewise, P. putida rhizobacteria showed the highest nitrogen (24.60 mg ∙ g−1 DM) and sulfur (2.60 mg ∙ g−1 DM) concentrations at a foliar level. The combination of GWI and Bacillus subtilis was the treatment that presented the highest calcium (16.00 mg ∙ g−1 DM) and magnesium (8.80 mg ∙ g−1 DM) concentrations. The microorganisms’ multifunctionality reduced disease severity by 85 to 90% due to the interaction between mycorrhizae and rhizobacteria. In conclusion, the use of growth promoting microorganisms that are antagonistic to P. cinnamomi represents a potential strategy for sustainable management of avocado cultivation. Full article
