Special Issue Information

Dear Colleagues,

Over the last century, a plethora of fungal microorganisms exerting beneficial effects on a wide variety of plant species have been described and characterized. Some of them enhance plant growth and yield production either by secreting volatile (VOCs) or nonvolatile metabolites or by directly interacting with plant roots and increasing nutrient availability or accessibility (i.e., fungal symbionts). Others modulate plant fitness indirectly through antibiosis, parasitism or competition with some of the biotic threats that compose the root microbiota and that continuously influence plant health throughout its entire life cycle (i.e., endophytes, entomopathogenic, mycoparasitic, and nematophagous fungi). Similarly, nonpathogenic isolates of closely related deadly pathogenic fungi offer protection to plants by modulating their resistance potential via induction of defense responses.

Despite major advances have been achieved in the last few decades on the modes of action employed by different beneficial fungal species, the molecular determinants of the crosstalk laying at the base of these fascinating fungal–plant or fungal–pathogen interactions are still far away from being clearly understood. Some of the main unresolved questions regard how and which microbial- or plant-derived signals mediate direct or indirect beneficial effects on plants and in microbiota composition. In this context, recent findings have also highlighted that harmed plants have the potential to reshape their root microbiome via the recruitment of beneficial microorganisms. Which fungal species act as plant “helpers” and the interkingdom dialogue occurring during plant–pathogen–helper tripartite interactions is still poorly understood.

In this context, Pathogens will launch a Special Issue devoted to “Beneficial Fungal Interactions with Plants or with Plant Pathogens”. This Special Issue will focus on those fungal species (and/or natural compounds) which mediate a positive effect on plant physiology or health status and will include both original research and review articles covering all aspects of the signaling events occurring among beneficial fungi, pathogens, and plants and leading to a positive output in terms of plant fitness (i.e., nutrient acquisition, growth promotion, and disease resistance).

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 papers will be 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. Pathogens 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 1400 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.

Organic Amendments Modulate Soil Microbiota and Reduce Virus Disease Incidence in the TSWV-Tomato Pathosystem

Application of organic amendments is considered an eco-friendly practice to promote soil fertility and suppressiveness against a wide range of soil-borne pathogens. However, limited information is available about the capabilities of organic amendments to control virus disease. In this study, the suppressiveness of different organic amendments (i.e., compost manure, biochar, alfalfa straw, and glucose) was determined against the Tomato spotted wilt virus (TSWV) on tomato plants in a 1-year-long mesocosm experiment. Organic treatments were compared to the ordinary soil management based on mineral fertilizers and fumigation. Tomato seedlings were inoculated with TSWV and the infection and symptoms were assessed three weeks later. The disease incidence was higher in soil treated with mineral fertilizers and fumigation (> 80%) compared to the application of organic amendments, with alfalfa straw and biochar recording the lowest incidence (< 40%). Moreover, soil microbiota structure and diversity were assessed by high-throughput sequencing of bacterial and eukaryotic rRNA gene markers. Several members belonging to the bacterial phyla of Acidobacteria, Actinobacteria, Bacteroidetes, and Proteobacteria, as well as members of the fungal genus Acremonium, were positively associated with plant health. This study showed that conventional practices, by shifting microbiome composition, may increase TSWV incidence and severity. Full article
