Baker & Mikael R. Andersen * Section Flavi encompasses both harmful and beneficial Aspergillus species, such as Aspergillus oryzae, used in food fermentation and enzyme production, and Aspergillus flavus, food spoiler and mycotoxin producer. Here, we sequence 19 genomes spanning section Flavi and compare 31 fungal genomes including 23 Flavi species. We reassess their phylogenetic relationships and show that the closest relative of A. oryzae is not A. flavus, but A. minisclerotigenes or A. aflatoxiformans and identify high genome diversity, especially in sub-telomeric regions. We predict abundant CAZymes (598 per species) and prolific secondary metabolite gene clus- ters (73 per species) in section Flavi. However, the observed phenotypes (growth char- acteristics, polysaccharide degradation) do not necessarily correlate with inferences made from the predicted CAZyme content. Our work, including genomic analyses, phenotypic assays, and identification of secondary metabolites, highlights the genetic and metabolic diversity within section Flavi. 1 Department of Biotechnology and Bioengineering, Technical University of Denmark, Søltoft Plads 223, 2800 Kongens Lyngby, Denmark. 2 US Department of Energy Joint Genome Institute, 2800 Mitchell Drive, Walnut Creek, CA 94598, USA. 3 Kikkoman Corporation, 250 Noda, 278-0037 Noda, Japan. 4 Fungal Physiology, Westerdijk Fungal Biodiversity Institute & Fungal Molecular Physiology, Utrecht University, Uppsalalaan 8, 3584 CT Utrecht, The Netherlands. 5 Department of Microbiology, Faculty of Agriculture and Forestry, University of Helsinki, Viikinkaari 9, Helsinki, Finland. 6 US Department of Energy Joint BioEnergy Institute, 5885 Hollis St., Emeryville, CA 94608, USA. 7 Architecture et Fonction des Macromolécules Biologiques, (CNRS UMR 7257, Aix- Marseille University, 163 Avenue de Luminy, Parc Scientifique et Technologique de Luminy, 13288 Marseille, France. 8 Department of Plant and Microbial Biology, University of California, 111 Koshland Hall, Berkeley, CA 94720, USA. 9 Kanazawa Institute of Technology, 3 Chome-1, 924-0838 Yatsukaho, Hakusan-shi, Ishikawa-ken, Japan. 10 Environmental Molecular Sciences Division, Earth and Biological Sciences Directorate, Pacific Northwest National Laboratory, 902 Battelle Blvd, Richland, WA 99354, USA. *email: [email protected] NATURE COMMUNICATIONS | (2020) 11:1106 | https://doi.org/10.1038/s41467-019-14051-y | www.nature.com/naturecommunications 1 ARTICLE NATURE COMMUNICATIONS | https://doi.org/10.1038/s41467-019-14051-y spergillus section Flavi encompasses a large number of alternative species for industrial use, combat pathogenicity, find A species, many of which have a significant impact on novel bioactives, and to identify useful enzymes.

  • The Phylogeny of Plant and Animal Pathogens in the Ascomycota

    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.

Houbraken1,2 and R.A. Samson1 1CBS-KNAW Fungal Biodiversity Centre, Uppsalalaan 8, 3584 CT Utrecht, The Netherlands; 2Microbiology, Department of Biology, Utrecht University, Padualaan 8, 3584 CH Utrecht, The Netherlands. *Correspondence: Jos Houbraken, [email protected] Abstract: Species of Trichocomaceae occur commonly and are important to both industry and medicine. They are associated with food spoilage and mycotoxin production and can occur in the indoor environment, causing health hazards by the formation of β-glucans, mycotoxins and surface proteins. Some species are opportunistic pathogens, while others are exploited in biotechnology for the production of enzymes, antibiotics and other products. Penicillium belongs phylogenetically to Trichocomaceae and more than 250 species are currently accepted in this genus. In this study, we investigated the relationship of Penicillium to other genera of Trichocomaceae and studied in detail the phylogeny of the genus itself. In order to study these relationships, partial RPB1, RPB2 (RNA polymerase II genes), Tsr1 (putative ribosome biogenesis protein) and Cct8 (putative chaperonin complex component TCP-1) gene sequences were obtained. The Trichocomaceae are divided in three separate families: Aspergillaceae, Thermoascaceae and Trichocomaceae. The Aspergillaceae are characterised by the formation flask-shaped or cylindrical phialides, asci produced inside cleistothecia or surrounded by Hülle cells and mainly ascospores with a furrow or slit, while the Trichocomaceae are defined by the formation of lanceolate phialides, asci borne within a tuft or layer of loose hyphae and ascospores lacking a slit.

    Lists of Names in Aspergillus and Teleomorphs As Proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (Doi: 10.3852/14-0

    Lists of names in Aspergillus and teleomorphs as proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (doi: 10.3852/14-060), based on retypification of Aspergillus with A. niger as type species John I. Pitt and John W. Taylor, CSIRO Food and Nutrition, North Ryde, NSW 2113, Australia and Dept of Plant and Microbial Biology, University of California, Berkeley, CA 94720-3102, USA Preamble The lists below set out the nomenclature of Aspergillus and its teleomorphs as they would become on acceptance of a proposal published by Pitt and Taylor (2014) to change the type species of Aspergillus from A. glaucus to A. niger. The central points of the proposal by Pitt and Taylor (2014) are that retypification of Aspergillus on A. niger will make the classification of fungi with Aspergillus anamorphs: i) reflect the great phenotypic diversity in sexual morphology, physiology and ecology of the clades whose species have Aspergillus anamorphs; ii) respect the phylogenetic relationship of these clades to each other and to Penicillium; and iii) preserve the name Aspergillus for the clade that contains the greatest number of economically important species. Specifically, of the 11 teleomorph genera associated with Aspergillus anamorphs, the proposal of Pitt and Taylor (2014) maintains the three major teleomorph genera – Eurotium, Neosartorya and Emericella – together with Chaetosartorya, Hemicarpenteles, Sclerocleista and Warcupiella. Aspergillus is maintained for the important species used industrially and for manufacture of fermented foods, together with all species producing major mycotoxins. The teleomorph genera Fennellia, Petromyces, Neocarpenteles and Neopetromyces are synonymised with Aspergillus. The lists below are based on the List of “Names in Current Use” developed by Pitt and Samson (1993) and those listed in MycoBank (www.MycoBank.org), plus extensive scrutiny of papers publishing new species of Aspergillus and associated teleomorph genera as collected in Index of Fungi (1992-2104).

This book is an introduction to the chemistry of fungal metabolites. The aim is to illustrate, within the context of fungal metabolites, the historical progression from chemical to spectroscopic methods of structure elucidation, the development in biosynthetic studies from establishing sequences and mechanisms to chemical enzymology and genetics and the increasing understanding of the biological roles of natural products.
