Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute papers for publication in our upcoming issue “Genes in Wheat Scab Fungus Fusarium graminearum”. Fusarium graminearum is a causal agent of Fusarium head blight (FHB), which is one of the most important diseases of wheat and barley worldwide. In addition to causing severe yield losses, F. graminearum is a producer of the trichothecene mycotoxin deoxynivalenol (DON), which is harmful to human and animal health. Currently, global warming, climate change and changes in cropping systems have made FHB epidemics more frequent and severe. Novel sustainable management strategies for crop protection must be developed.

This Special Issue aims to attract studies that contribute to enhance our understanding on pathogen biology, host–pathogen interactions, host resistance to diseases, and disease management related to FHB. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: 1) biology of F. graminearum towards gaining greater insight into the infection process and the weak spots in the disease cycles; 2) biosynthesis and regulation of trichothecene mycotoxins in F. graminearum; 3) interaction between F. graminearum and its hosts, and plant immunity against F. graminearum; 4) new strategies towards the control of FHB and trichothecene mycotoxins production; 5) population diversity and adaptive evolution of F. graminearum revealed by genomics and population genomics.

We look forward to receiving your contributions.

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.

The Fusarium graminearum species complex is the main causal agent of wheat head blight worldwide. Trichothecenes produced by the pathogen in infected grains have important food safety implications. Previously reported studies on trichothecene production have all focused on the conditions conducive to mycotoxin production, while the molecular mechanisms of trichothecene biosynthesis in Fusarium strains under normal or non-inducing conditions are still unclear. Here, a global analysis of the fungal gene expression of three strains using the Affymetrix Fusarium GeneChip under non-inducing conditions is reported. Differentially expressed genes were identified among strains with different trichothecene-production ability, and some novel genes associated with trichothecene biosynthesis were found by bioinformatics analysis. To verify the transcriptome results, proteomic analyses of the three strains were conducted under the same culture conditions. In total, 69 unique fungal proteins were identified in 77 protein spots. Combined with transcriptome and proteome analysis, 27 novel genes were predicted to be associated with trichothecene mycotoxin production. A protein, encoded by FGSG_01403, was found to be associated with trichothecene production via proteome analysis. Gene knock-out mutations of FGSG_01403 resulted in mutants with increased production of trichothecenes. Future functional analysis of the candidate genes identified in this study may reveal new insights into the negative regulation of trichothecene production in the Fusarium graminearum species complex.
