Special Issue Information

Dear Colleagues,

Fungi are among the most dominant causal agents of plant diseases. In addition to causing yield and quality losses, many fungal pathogens produce mycotoxins to contaminate crops before or after harvest, posing a threat to our food and feed safety. Understanding the regulating mechanisms of fungal pathogens’ vegetative growth, sexual/asexual reproduction, toxin biosynthesis, pathogenesis and host–pathogen interactions is critical for developing effective strategies to control plant diseases. In recent years, scientific and technological advances have significantly promoted progress in the research on plant fungal pathogens.

We welcome research and review manuscripts focused on plant diseases caused by fungi or fungal-like organisms. Topics of interest for this Special Issue of the Journal of Fungi include, but are not limited to, the following:

  1. Biology of plant fungal pathogens including vegetative growth, conidiation, and sexual development;
  2. Mycotoxin biosynthesis;
  3. Pathogenesis;
  4. Host–pathogen interactions;
  5. Effects of abiotic and biotic environmental factors.

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. 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.

Protein phosphatases are crucial enzymes that regulate key cellular processes such as the cell cycle, gene transcription, and translation in eukaryotes. Seven PP2C protein phosphatases have been identified in Magnaporthe oryzae. However, their synergistic roles in the pathology and physiology of M. oryzae remain poorly investigated. By qRT-PCR analysis, we found that PTC1 and PTC2 are significantly upregulated in the PTC5 deletion mutant. The double deletion of the MoPTC5/MoPTC1 and MoPTC5/MoPTC2 genes significantly reduced hyphal growth, conidiophore formation, sporulation, and virulence in M. oryzae. In addition, the double-knockout mutants were increasingly sensitive to different osmotic, oxidative, and cell wall stresses. Western blot analysis revealed that MoPtc5 plays a synergistic function with MoPtc1 and MoPtc2 in the regulation of MoMps1 and MoOsm1 phosphorylation levels. Lastly, appressorium formation and turgor generation were remarkably affected in the ΔMoptc5ΔMoptc1 and ΔMoptc5ΔMoptc2 double-deletion mutants. These findings demonstrate the overlapping roles of PP2c protein phosphatase in the fungal development and pathogenesis of M. oryzae. Full article
