Abstract Background: Current tools for Co-phylogenetic analyses are not able to cope with the continuous accumulation of phylogenetic data. The sophisticated statistical test for host-parasite co-phylogenetic analyses implemented in Parafit does not allow it to handle large datasets in reasonable times. The Parafit and DistPCoA programs are the by far most compute-intensive components of the Parafit analysis pipeline. -
Revisiting the Concept of Host Range of Plant Pathogens

For personal use only. factors that influence the outcome of plant–microorganism interactions, the spatial and temporal dynamics of these factors, and the diversity of any given pathogen makes it increasingly challenging to define simple, all-purpose rules to circumscribe the host range of a pathogen. For bacteria, fungi, oomycetes, and viruses, we illustrate that host range is often an overlapping continuum—more so than the separation of discrete pathotypes—and that host jumps are common. By setting the mechanisms of plant–pathogen in- teractions into the scales of contemporary land use and Earth history, we propose a framework to assess the frontiers of host range for practical appli- cations and research on pathogen evolution. -
LUNDY FUNGI: FURTHER SURVEYS 2004-2008 by JOHN N
Journal of the Lundy Field Society, 2, 2010 LUNDY FUNGI: FURTHER SURVEYS 2004-2008 by JOHN N. HEDGER1, J. DAVID GEORGE2, GARETH W. GRIFFITH3, DILUKA PEIRIS1 1School of Life Sciences, University of Westminster, 115 New Cavendish Street, London, W1M 8JS 2Natural History Museum, Cromwell Road, London, SW7 5BD 3Institute of Biological Environmental and Rural Sciences, University of Aberystwyth, SY23 3DD Corresponding author, e-mail: [email protected] ABSTRACT The results of four five-day field surveys of fungi carried out yearly on Lundy from 2004-08 are reported and the results compared with the previous survey by ourselves in 2003 and to records made prior to 2003 by members of the LFS. 240 taxa were identified of which 159 appear to be new records for the island. Seasonal distribution, habitat and resource preferences are discussed. Keywords: Fungi, ecology, biodiversity, conservation, grassland INTRODUCTION Hedger & George (2004) published a list of 108 taxa of fungi found on Lundy during a five-day survey carried out in October 2003. They also included in this paper the records of 95 species of fungi made from 1970 onwards, mostly abstracted from the Annual Reports of the Lundy Field Society, and found that their own survey had added 70 additional records, giving a total of 156 taxa. They concluded that further surveys would undoubtedly add to the database, especially since the autumn of 2003 had been exceptionally dry, and as a consequence the fruiting of the larger fleshy fungi on Lundy, especially the grassland species, had been very poor, resulting in under-recording. Further five-day surveys were therefore carried out each year from 2004-08, three in the autumn, 8-12 November 2004, 4-9 November 2007, 3-11 November 2008, one in winter, 23-27 January 2006 and one in spring, 9-16 April 2005. -

Mykologie in Tübingen 1974-2011
Mykologie am Lehrstuhl Spezielle Botanik und Mykologie der Universität Tübingen, 1974-2011 FRANZ OBERWINKLER Kurzfassung Wir beschreiben die mykologischen Forschungsaktivitäten am ehemaligen Lehrstuhl „Spezielle Botanik und Mykologie“ der Universität Tübingen von 1974 bis 2011 und ihrer internationalen Ausstrahlung. Leitschiene unseres gemeinsamen mykologischen Forschungskonzeptes war die Verknüpfung von Gelände- mit Laborarbeiten sowie von Forschung mit Lehre. Dieses Konzept spiegelte sich in einem weit gefächerten Lehrangebot, das insbesondere den Pflanzen als dem Hauptsubstrat der Pilze breiten Raum gab. Lichtmikroskopische Untersuchungen der zellulären Baupläne von Pilzen bildeten das Fundament für unsere Arbeiten: Identifikationen, Ontogeniestudien, Vergleiche von Mikromorphologien, Überprüfen von Kulturen, Präparateauswahl für Elektronenmikroskopie, etc. Bereits an diesen Beispielen wird die Methodenvernetzung erkennbar. In dem zu besprechenden Zeitraum wurden Ultrastrukturuntersuchungen und Nukleinsäuresequenzierungen als revolutionierende Methoden für den täglichen Laborbetrieb verfügbar. Flankiert wurden diese Neuerungen durch ständig verbesserte Datenaufbereitungen und Auswertungsprogramme für Computer. Zusammen mit den traditionellen Anwendungen der Lichtmikroskopie und der Kultivierung von Pilzen stand somit ein effizientes Methodenspektrum zur Verfügung, das für systematische, phylogenetische und ökologische Fragestellungen gleichermaßen eingesetzt werden konnte, insbesondere in der Antibiotikaforschung, beim Studium zellulärer -

Molecular Phylogeny of Ustilago and Sporisorium Species (Basidiomycota, Ustilaginales) Based on Internal Transcribed Spacer (ITS) Sequences1
Color profile: Disabled Composite Default screen 976 Molecular phylogeny of Ustilago and Sporisorium species (Basidiomycota, Ustilaginales) based on internal transcribed spacer (ITS) sequences1 Matthias Stoll, Meike Piepenbring, Dominik Begerow, Franz Oberwinkler Abstract: DNA sequence data from the internal transcribed spacer (ITS) region of the nuclear rDNA genes were used to determine a phylogenetic relationship between the graminicolous smut genera Ustilago and Sporisorium (Ustilaginales). Fifty-three members of both genera were analysed together with three related outgroup genera. Neighbor-joining and Bayesian inferences of phylogeny indicate the monophyly of a bipartite genus Sporisorium and the monophyly of a core Ustilago clade. Both methods confirm the recently published nomenclatural change of the cane smut Ustilago scitaminea to Sporisorium scitamineum and indicate a putative connection between Ustilago maydis and Sporisorium. Overall, the three clades resolved in our analyses are only weakly supported by morphological char- acters. Still, their preferences to parasitize certain subfamilies of Poaceae could be used to corroborate our results: all members of both Sporisorium groups occur exclusively on the grass subfamily Panicoideae. The core Ustilago group mainly infects the subfamilies Pooideae or Chloridoideae. Key words: basidiomycete systematics, ITS, molecular phylogeny, Bayesian analysis, Ustilaginomycetes, smut fungi. Résumé : Afin de déterminer la relation phylogénétique des genres Ustilago et Sporisorium (Ustilaginales), responsa- bles du charbon chez les graminées, les auteurs ont utilisé les données de séquence de la région espaceur transcrit interne (ITS) des gènes nucléiques ADNr. Ils ont analysé 53 membres de ces genres, ainsi que trois genres apparentés. Les liens avec les voisins et l’inférence bayésienne de la phylogénie indiquent la monophylie d’un genre Sporisorium bipartite et la monophylie d’un clade Ustilago central. -

Dreyer 2, M.J. Wingfield 3, D. Begerow 4 Key words Abstract The smut genus Thecaphora contains plant parasitic microfungi that typically infect very specific plant organs. In this study, we describe a new species of Thecaphora from Oxalis lanata var. rosea (Oxalidaceae) in the anther-smut Cape Floristic Region of South Africa. Molecular phylogenetic reconstructions based on large subunit ribosomal Cape Floristic Region DNA sequence data confirmed the generic placement of the fungus and confirmed that it represents an undescribed Oxalis species for which the name T. capensis sp. nov. is provided. The closest known sister species of the new taxon is phylogeny T. oxalidis that infects the fruits of Oxalis spp. in Europe, Asia and the Americas. In contrast, T. capensis produces Thecaphora teliospores within the anthers of its host. This is the first documented case of an anther-smut from an African spe- cies of Oxalis and the first Thecaphora species described from Africa.

McTaggart1,2,3,5, R.G. Shivas1,2, A.D.W. Geering1,2,5, K. Vánky4, T. Scharaschkin1,3 Key words Abstract The fungal genera Ustilago, Sporisorium and Macalpinomyces represent an unresolved complex. Taxa within the complex often possess characters that occur in more than one genus, creating uncertainty for species smut fungi placement. Previous studies have indicated that the genera cannot be separated based on morphology alone. systematics Here we chronologically review the history of the Ustilago-Sporisorium-Macalpinomyces complex, argue for its Ustilaginaceae resolution and suggest methods to accomplish a stable taxonomy. A combined molecular and morphological ap- proach is required to identify synapomorphic characters that underpin a new classification. Ustilago, Sporisorium and Macalpinomyces require explicit re-description and new genera, based on monophyletic groups, are needed to accommodate taxa that no longer fit the emended descriptions. A resolved classification will end the taxonomic confusion that surrounds generic placement of these smut fungi.
