Special Issue Information

Dear Colleagues,

DNA sequencing technology has revolutionized the taxonomy and diagnostics of true fungi and oomycetes, here referred to as fungi in a broad sense. Whole-genome sequencing of plant pathogens made the targeted design of primers for molecular diagnosis possible, next-generation sequencing proved to be a powerful tool to study the plant-associated microbiomes and the multi-locus sequence phylogeny resulted in a substantial taxonomic and nomenclatural revision of families and genera, including those of important plant pathogens. However, defining species boundaries is still challenging, and plant pathologists feel the need for a more stable molecular taxonomy. Moreover, not all fungi associated with plants are pathogens, and many shift to an aggressive pathogenic lifestyle when environmental conditions are favorable or the host plant is stressed. A promising aspect of a molecular taxonomy that also takes functional aspects into consideration is the search for genetic markers predicting the pathogenetic potential of fungi.

The aim of this Special Issue is to stimulate the debate on the implications of molecular taxonomy for both plant pathology and crop breeding for disease resistance. This Special Issue welcomes reviews addressing these general topics and scientific contributions demonstrating the usefulness of molecular techniques in identifying fungi associated with agricultural and forestry plants.

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.

Alternaria is a saprophytic and opportunistic fungus with a worldwide distribution that can affect the quality of various agricultural products, such as fruits, cereals, and pseudocereals. This research was carried out to investigate the population of this genus associated with quinoa cultivation in plots located in the Boyacá department (Colombia), the country’s third-largest quinoa-producing department. The present study found 17 Alternaria isolates, of which 13 were identified as A. alternata and 4 as A. scrophulariae (formerly A. conjuncta) employed molecular markers of internal transcribed spacer (ITS) region and translation elongation factor 1α (TEF-1α). In the pathogenicity test under greenhouse conditions, all the Alternaria isolates showed some degree of pathogenicity on Piartal quinoa cultivar plants although no significant differences were found in isolates. The severity indices ranged from 2 to 5, and the percentage of affected leaves per plant ranged between 15% and 40%. This fungus affected the foliar tissue of quinoa, resulting in chlorotic and necrotic spots, symptoms that can generate a reduction in the quality and productivity of crops. This is the first time that the pathogenicity of Alternaria spp. in the Piartal variety has been described and the first report of this genera in quinoa crops of Colombia. Full article
