Special Issue Information

Dear Colleagues,

Arbuscular Mycorrhizal Fungi (AMF) play a crucial role in terrestrial ecosystems, promoting plant growth through symbiotic associations with roots. Recent studies have highlighted the remarkable diversity within AMF communities, revealing a wide range of species adapted to different environmental conditions. This taxonomic complexity is essential for understanding their ecological functions and evolutionary relationships. Advances in molecular techniques, such as high-throughput sequencing and metagenomics, have uncovered cryptic species and provided a clearer picture of their phylogeny. Moreover, the application of AMF extends beyond natural ecosystems, showing their potential in sustainable agriculture and in the production of molecules relevant to industries. By enhancing nutrient uptake and improving plant resilience to stress, AMF inoculants are being explored to reduce chemical fertilizer dependency. Understanding the diversity, application, and taxonomy of AMF is, therefore, vital for developing tailored biofertilizers and promoting ecosystem restoration, paving the way for more resilient and productive agroecosystems in a changing world.

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. 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.

Drought stress significantly hinders the cultivation of medicinal plants such as licorice (Glycyrrhiza uralensis), valued for its bioactive compounds, glycyrrhizin, and liquiritin. This study aims to investigate how co-inoculation with arbuscular mycorrhizal fungus Rhizophagus irregularis and Trichoderma harzianum can enhance licorice drought tolerance and secondary metabolite production, providing insights for sustainable agriculture in arid regions. The results demonstrate that inoculation with R. irregularis significantly improved biomass, drought stress tolerance, and increased glycyrrhizin and liquiritin concentrations by 29.9% and 3.3-fold, respectively, particularly under drought conditions. Co-inoculation with T. harzianum further boosted glycyrrhizin yield by 93.7%, indicating a synergistic relationship between the two microbes. The expression of key biosynthetic genes, including squalene synthase (SQS1) for glycyrrhizin and chalcone synthase (CHS) for liquiritin, was significantly upregulated, enhancing water use efficiency and the biosynthesis of secondary metabolites. Nutrient analysis showed improved phosphorus uptake, alongside reduced root carbon and nitrogen concentrations, leading to greater nutrient utilization efficiency. These findings suggest that co-inoculating R. irregularis and T. harzianum is a promising approach to improving licorice growth and medicinal quality under drought stress, with broad applications for sustainable crop management.
