Houbraken, [email protected]; J.C. Frisvad, [email protected] Abstract: The Eurotiales is a relatively large order of Ascomycetes with members frequently having positive and negative impact on human activities. Species within this order gain attention from various research fields such as food, indoor and medical mycology and biotechnology. In this article we give an overview of families and genera present in the Eurotiales and introduce an updated subgeneric, sectional and series classification for Aspergillus and Penicillium. Finally, a comprehensive list of accepted species in the Eurotiales is given. The classification of the Eurotiales at family and genus level is traditionally based on phenotypic characters, and this classification has since been challenged using sequence-based approaches. Here, we re-evaluated the relationships between families and genera of the Eurotiales using a nine-gene sequence dataset. Based on this analysis, the new family Penicillaginaceae is introduced and four known families are accepted: Aspergillaceae, Ela- phomycetaceae, Thermoascaceae and Trichocomaceae. The Eurotiales includes 28 genera: 15 genera are accommodated in the Aspergillaceae (Aspergillago, Aspergillus, Evansstolkia, Hamigera, Leiothecium, Monascus, Penicilliopsis, Penicillium, Phialomyces, Pseudohamigera, Pseudopenicillium, Sclerocleista, Warcupiella, Xerochrysium and Xeromyces), eight in the Trichocomaceae (Acidotalaromyces, Ascospirella, Dendrosphaera, Rasamsonia, Sagenomella, Talaromyces, Thermomyces, Trichocoma), two in the Thermoascaceae (Paecilomyces, Thermoascus) and one in the Penicillaginaceae (Penicillago). The classification of the Elaphomycetaceae was not part of this study, but according to literature two genera are present in this family (Elaphomyces and Pseudotulostoma). The use of an infrageneric classification system has a long tradition in Aspergillus and Penicillium. Most recent taxonomic studies focused on the sectional level, resulting in a well-established sectional classification in these genera. In contrast, a series classification in Aspergillus and Penicillium is often outdated or lacking, but is still relevant, e.g., the allocation of a species to a series can be highly predictive in what functional characters the species might have and might be useful when using a phenotype-based identification. The majority of the series in Aspergillus and Penicillium are invalidly described and here we introduce a new series classification. Using a phylogenetic approach, often supported by phenotypic, physiologic and/or extrolite data, Aspergillus is subdivided in six subgenera, 27 sections (five new) and 75 series (73 new, one new com- bination), and Penicillium in two subgenera, 32 sections (seven new) and 89 series (57 new, six new combinations). Correct identification of species belonging to the Eurotiales is difficult, but crucial, as the species name is the linking pin to information. Lists of accepted species are a helpful aid for researchers to obtain a correct identification using the current taxonomic schemes. In the most recent list from 2014, 339 Aspergillus, 354 Penicillium and 88 Talaromyces species were accepted. These numbers increased significantly, and the current list includes 446 Aspergillus (32 % increase), 483 Penicillium (36 % increase) and 171 Talaromyces (94 % increase) species, showing the large diversity and high interest in these genera. We expanded this list with all genera and species belonging to the Eurotiales (except those belonging to Elaphomycetaceae). The list includes 1187 species, distributed over 27 genera, and contains MycoBank numbers, collection numbers of type and ex-type cultures, subgenus, section and series classification data, information on the mode of reproduction, and GenBank accession numbers of ITS, beta-tubulin (BenA), calmodulin (CaM) and RNA polymerase II second largest subunit (RPB2) gene sequences.

Larsen * Department of Biotechnology and Biomedicine, Technical University of Denmark, Søltofts Plads, Building 221, DK-2800 Kgs. Lyngby, Denmark; [email protected] (Y.G.); [email protected] (J.C.F.) * Correspondence: [email protected]; Tel.: +45-4525-2632 Received: 12 May 2020; Accepted: 8 June 2020; Published: 15 June 2020 Abstract: Recently, a rare class of nonribosomal peptides (NRPs) bearing a unique Oxepine-Pyrimidinone-Ketopiperazine (OPK) scaffold has been exclusively isolated from fungal sources. Based on the number of rings and conjugation systems on the backbone, it can be further categorized into three types A, B, and C. These compounds have been applied to various bioassays, and some have exhibited promising bioactivities like antifungal activity against phytopathogenic fungi and transcriptional activation on liver X receptor α. This review summarizes all the research related to natural OPK NRPs, including their biological sources, chemical structures, bioassays, as well as proposed biosynthetic mechanisms from 1988 to March 2020. The taxonomy of the fungal sources and chirality-related issues of these products are also discussed. Keywords: oxepine; nonribosomal peptides; bioactivity; biosynthesis; fungi; Aspergillus 1. Introduction Nonribosomal peptides (NRPs), mostly found in bacteria and fungi, are a class of peptidyl secondary metabolites biosynthesized by large modularly organized multienzyme complexes named nonribosomal peptide synthetases (NRPSs) [1]. These products are amongst the most structurally diverse secondary metabolites in nature; they exhibit a broad range of activities, which have been exploited in treatments such as the immunosuppressant cyclosporine A and the antibiotic daptomycin [2,3].

Tissue fragments were analyzed on potato-glucose agar (PDA) and maltose (MA) (Difco) media using standard laboratory techniques. Cultures were identified using classi- cal and molecular methods. Macro- and microscopic colony morphology was characteristic of fungi from the genus Aspergillus (restricted growth series), most probably Aspergillus penicillioides Speg. Molecular analysis of the following rDNA regions: ITS1, ITS2, 5.8S, 28S rDNA, LSU and β-tubulin were carried out for the isolates studied. A high level of similarity was found between sequences from certain rDNA regions, i.e. ITS1-5.8S-ITS2 and LSU, what confirmed the classification of the isolates to the species A. penicillioides. The classification of our isolates to A. penicillioides species was confirmed also by the phylogenetic analysis.

  • ABSTRACT LEWIS, MARY HUNT. Genetic Structure of Soil
    ABSTRACT LEWIS, MARY HUNT. Genetic Structure of Soil Populations of Aspergillus Section Flavi and Efficacy of Biocontrol of Aflatoxin Contamination in Corn. (Under the direction of Dr. Ignazio Carbone and Dr. Peter S. Ojiambo). Corn is contaminated with aflatoxin, a carcinogenic mycotoxin, when aflatoxigenic strains within Aspergillus section Flavi infect corn kernels. Biocontrol using non- aflatoxigenic strains of A. flavus have been shown to have the greatest potential to control aflatoxin contamination in corn. However, factors that influence the efficacy of biocontrol agents in different locations are not fully understood. One factor affecting the effectiveness biocontrol could be the genetic structure of the native soil populations of Aspergillus section Flavi. In this study, we investigated how the genetic structure of native soil populations of Aspergillus section Flavi could impact the effectiveness of two commercially available biological control products in different locations in the southeastern US. Field trials were conducted in Alabama, Georgia and North Carolina in the 2012 and 2013 growing seasons. Biocontrol products AF36 and Afla-Guard® were applied to the corn at the VT stage. Soil samples were collected prior to and 1-week after biocontrol application and at harvest to determine the genetic structure of soil populations. In all states, A. flavus (61-100%) was the most dominant species within section Flavi, with A. parasiticus (<35%) being the second- most frequently isolated species. A. nomius, A. caelatus and A. tamarii were detected only in Alabama, but at very low frequencies (<5%). Multi-locus sequence typing revealed that prior to biocontrol application in North Carolina in 2012, 48% of the isolates were the same haplotype as the biocontrol strain Afla-Guard, which belongs to lineage IB, while only 6% were of the same haplotype as AF36, which belongs to lineage IC.

Moldagulova avenue, 34 Abstract With the use of classical identification methods, which imply the identification of fungi by cultural and morphological features, they may not be reliable. With the development of modern molecular methods, it became possible to quickly and accurately determine the species and race of the fungus. The purpose of this work was to study bioecology and refine the species composition of fungi of the genus Aspergillus, Penicillium on seeds of cereal crops. The article presents materials of scientific research on morphological and molecular genetic peculiarities of storage fungi, affecting seeds of grain crops. Particular attention is paid to the fungi that develop in the stored grain. The seeds of cereals (Triticum aestivum L., Avena sativa L., Hordeum vulgare L., Zea mays L., Oryza sativa L., Sorghum vulgare Pers., Panicum miliaceum L.) were collected from the granaries of five districts (Talgar, Iliysky, Karasai, Zhambul, Panfilov) of the Almaty region. The pathogens of diseases of fungal etiology were found from the genera Penicillium, Aspergillus influencing the safety, quality and safety of the grain.

A total of 25 isolates were identified into ten genera based on internal transcribed spacer region (ITS) sequence analysis, namely Aspergillus, Clonostachys, Colletotrichum, Curvularia, Gliocladiopsis, Metarhizium, Myrmecridium, Penicillium, Scedosporium and Trichoderma consisting 18 fungi species. Aspergillus and Penicillium species were claimed as predominant microfungi inhabiting the soil. Findings from this study can be used as a checklist for future studies related to fungi distribution in tropical lands. For improving further study, factors including the physicochemical properties of soil and anthropogenic activities in the sampling area should be included.

  • The Phylogeny of Plant and Animal Pathogens in the Ascomycota
    Physiological and Molecular Plant Pathology (2001) 59, 165±187 doi:10.1006/pmpp.2001.0355, available online at http://www.idealibrary.com on MINI-REVIEW The phylogeny of plant and animal pathogens in the Ascomycota MARY L. BERBEE* Department of Botany, University of British Columbia, 6270 University Blvd, Vancouver, BC V6T 1Z4, Canada (Accepted for publication August 2001) What makes a fungus pathogenic? In this review, phylogenetic inference is used to speculate on the evolution of plant and animal pathogens in the fungal Phylum Ascomycota. A phylogeny is presented using 297 18S ribosomal DNA sequences from GenBank and it is shown that most known plant pathogens are concentrated in four classes in the Ascomycota. Animal pathogens are also concentrated, but in two ascomycete classes that contain few, if any, plant pathogens. Rather than appearing as a constant character of a class, the ability to cause disease in plants and animals was gained and lost repeatedly. The genes that code for some traits involved in pathogenicity or virulence have been cloned and characterized, and so the evolutionary relationships of a few of the genes for enzymes and toxins known to play roles in diseases were explored. In general, these genes are too narrowly distributed and too recent in origin to explain the broad patterns of origin of pathogens. Co-evolution could potentially be part of an explanation for phylogenetic patterns of pathogenesis. Robust phylogenies not only of the fungi, but also of host plants and animals are becoming available, allowing for critical analysis of the nature of co-evolutionary warfare. Host animals, particularly human hosts have had little obvious eect on fungal evolution and most cases of fungal disease in humans appear to represent an evolutionary dead end for the fungus.
