    Abstract:

    The order Sordariales includes the polyphyletic family Lasiosphaeriaceae, which comprises approximately 30 genera characterized by its paraphysate ascomata, asci with apical apparati, and mostly two-celled ascospores, which have a dark apical cell and a hyaline lower cell, frequently ornamented with mucilaginous appendages[...].

  • A re-evaluation of the genus Myceliophthora (Sordariales, Ascomycota): its segregation into four genera and description of Corynascus fumimontanus sp. nov.
    Mycologia, 2015
    Co-Authors: Yasmina Marin-felix, Josep Guarro, Alberto Miguel Stchigel, Andrew N. Miller, José F. Cano-lira
    Abstract:

    Based on a number of isolates of Myceliophthora (Chaetomiaceae, Sordariales, Ascomycota) recently isolated from soil samples collected in USA, the taxonomy of the genus was re-evaluated through phylogenetic analyses of sequences from the nuc rDNA internal transcribed spacer region and genes for the second largest subunit of RNA polymerase II and translation elongation factor 1α. Members of Myceliophthora were split into four monophyletic clades strongly supported by molecular and phenotypic data. Such clades correspond with Myceliophthora, now restricted only to the type species of the genus Corynascus, which is re-established with five species, the new monotypic genus Crassicarpon and also the new genus Thermothelomyces (comprising four species). Myceliophthora lutea is mesophilic and a permanently asexual morph compared to the members of the other three mentioned genera, which also are able to sexually reproduce morphs with experimentally proven links to their asexual morphs. The asexual morph of M. lut...

  • Coprophilous contributions to the phylogeny of Lasiosphaeriaceae and allied taxa within Sordariales (Ascomycota, Fungi)
    Fungal Diversity, 2015
    Co-Authors: Åsa Kruys, Sabine M. Huhndorf, Andrew N. Miller
    Abstract:

    The phylogenetic relationships of Lasiosphaeriaceae are complicated in that the family is paraphyletic and includes Sordariaceae and Chaetomiaceae , as well as several polyphyletic genera. This study focuses on the phylogenetic relationships of the coprophilous genera, Anopodium, Apodospora, Arnium, Fimetariella and Zygospermella. They are traditionally circumscribed based on ascospore characters, which have proven homoplasious in other genera within the family . Our results based on LSU nrDNA and ß–tubulin sequences distinguish four lineages of Lasiosphaeriaceae taxa. Anopodium joins the clade of morphologically similar, yellow-pigmented species of Cercophora and Lasiosphaeria. Apodospora is monophyletic and joins a larger group of taxa with unclear affinities to each other, while Arnium is polyphyletic being scattered throughout three of the four major clades of Lasiosphaeriaceae. Fimitariella is represented by a single collection and joins the clade containing Cercophora scortea and Podospora appendiculata. Zygospermella shows affinities to the Lasiosphaeris clade. Based on a combination of morphological and molecular data, Echria stat. nov . is recognized at the genus level for the former Arnium section and two new combinations are proposed: E. gigantospora and E. macrotheca.

  • Phialemoniopsis, a new genus of Sordariomycetes, and new species of Phialemonium and Lecythophora.
    Mycologia, 2012
    Co-Authors: Haybrig Perdomo, Dania García, Josepa Gene, Josep Cano, Deanna A. Sutton, Richard C. Summerbell, Josep Guarro
    Abstract:

    In molecular studies involving numerous clinical isolates of the genera Acremonium, Phialemonium and Lecytophora some of them could not be identified. To clarify the phylogenetic relationships among these fungi and other related taxa, we performed a polyphasic study based on a detailed morphological study and on the analysis of sequences of four loci: the internal transcribed spacer regions, the D1/D2 domains of the 28S rRNA, actin and β-tubulin genes. The combination of the resulting data let us propose the new genus Phialemoniopsis to accommodate the opportunistic fungi Phialemonium curvatum and Sarcopodium oculorum and two new species, Phialemoniopsis cornearis and Phialemoniopsis pluriloculosa. The taxonomy of Phialemoniopsis has not been completely resolved, however, remaining incertae sedis within the Sordariomycetes. In addition, the new species Lecythophora luteorubra, Lecythophora cateniformis and Phialemonium globosum are described and the species Acremonium atrogriseum and Taifanglania inflata are transferred to the genus Phialemonium. Lecythophora and Phialemonium are currently monophyletic genera of the families Coniochaetaceae (Coniochaetales) and Cephalothecaceae (Sordariales) respectively, according to our results. Tables summarizing key morphological features to distinguish the current species of Lecythophora, Phialemonium and Phialemoniopsis are provided.

  • Sordaria macrospora: 25 years as a model organism for studying the molecular mechanisms of fruiting body development
    Applied Microbiology and Biotechnology, 2020
    Co-Authors: Ines Teichert, Stefanie Pöggeler, Minou Nowrousian
    Abstract:

    Fruiting bodies are among the most complex multicellular structures formed by fungi, and the molecular mechanisms that regulate their development are far from understood. However, studies with a number of fungal model organisms have started to shed light on this developmental process. One of these model organisms is Sordaria macrospora , a filamentous ascomycete from the order Sordariales . This fungus has been a genetic model organism since the 1950s, but its career as a model organism for molecular genetics really took off in the 1990s, when the establishment of a transformation protocol, a mutant collection, and an indexed cosmid library provided the methods and resources to start revealing the molecular mechanisms of fruiting body development. In the 2000s, “omics” methods were added to the S. macrospora tool box, and by 2020, 58 developmental genes have been identified in this fungus. This review gives a brief overview of major method developments for S. macrospora , and then focuses on recent results characterizing different processes involved in regulating development including several regulatory protein complexes, autophagy, transcriptional and chromatin regulation, and RNA editing. Key points • Sordaria macrospora is a model system for analyzing fungal fruiting body development. • More than 100 developmental mutants are available for S. macrospora. • More than 50 developmental genes have been characterized in S. macrospora.

  • Suppression subtractive hybridization and comparative expression analysis to identify developmentally regulated genes in filamentous fungi
    Journal of basic microbiology, 2012
    Co-Authors: Stefan Gesing, Daniel Schindler, Minou Nowrousian
    Abstract:

    Ascomycetes differentiate four major morphological types of fruiting bodies (apothecia, perithecia, pseudothecia and cleistothecia) that are derived from an ancestral fruiting body. Thus, fruiting body differentiation is most likely controlled by a set of common core genes. One way to identify such genes is to search for genes with evolutionary conserved expression patterns. Using suppression subtractive hybridization (SSH), we selected differentially expressed transcripts in Pyronema confluens (Pezizales) by comparing two cDNA libraries specific for sexual and for vegetative development, respectively. The expression patterns of selected genes from both libraries were verified by quantitative real time PCR. Expression of several corresponding homologous genes was found to be conserved in two members of the Sordariales (Sordaria macrospora and Neurospora crassa), a derived group of ascomycetes that is only distantly related to the Pezizales. Knockout studies with N. crassa orthologues of differentially regulated genes revealed a functional role during fruiting body development for the gene NCU05079, encoding a putative MFS peptide transporter. These data indicate conserved gene expression patterns and a functional role of the corresponding genes during fruiting body development; such genes are candidates of choice for further functional analysis.

  • Evolution of multicopper oxidase genes in coprophilous and non-coprophilous members of the order Sordariales.
    Current genomics, 2011
    Co-Authors: Stefanie Pöggeler
    Abstract:

    Multicopper oxidases (MCO) catalyze the biological oxidation of various aromatic substrates and have been identified in plants, insects, bacteria, and wood rotting fungi. In nature, they are involved in biodegradation of biopolymers such as lignin and humic compounds, but have also been tested for various industrial applications. In fungi, MCOs have been shown to play important roles during their life cycles, such as in fruiting body formation, pigment formation and pathogenicity. Coprophilous fungi, which grow on the dung of herbivores, appear to encode an unexpectedly high number of enzymes capable of at least partly degrading lignin. This study compared the MCO-coding capacity of the coprophilous filamentous ascomycetes Podospora anserina and Sordaria macrospora with closely related non-coprophilous members of the order Sordariales. An increase of MCO genes in coprophilic members of the Sordariales most probably occurred by gene duplication and horizontal gene transfer events.
