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.

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.

Ils ont analysé 53 membres de ces genres, ainsi que trois genres apparentés.

It is endemic to West Java, Indonesia, specifically around Mount Gede, Mount Pangaro and south of Sukabumi. The Bleeding Toad’s scientific name, cruentata, is from the Latin word meaning “bleeding” because of the frog’s overall reddish-purple appearance and blood-red and yellow marbling on its back. Geographical range The population declined drastically after the eruption of Mount Galunggung in 1987. It is Knowledge believed that other declining factors may be habitat alteration, loss, and fragmentation. Experts Although the lethal chytrid fungus, responsible for devastating declines (and possible Get Involved extinctions) in amphibian populations globally, has not been recorded in this area, the sudden decline in a creekside population is reminiscent of declines in similar amphibian species due to the presence of this pathogen. Only one individual Bleeding Toad was sighted from 1990 to 2003. Part of the range of Bleeding Toad is located in Gunung Gede Pangrango National Park. Future conservation actions should include population surveys and possible captive breeding plans. The production of the IUCN Red List of Threatened Species™ is made possible through the IUCN Red List Partnership.

Anthracoidea Transberingiana, a New Smut Species on Carex Pauciflora from Beringia
Phytotaxa 174 (2): 105–110 ISSN 1179-3155 (print edition) www.mapress.com/phytotaxa/ PHYTOTAXA Copyright © 2014 Magnolia Press Article ISSN 1179-3163 (online edition) http://dx.doi.org/10.11646/phytotaxa.174.2.5 Anthracoidea transberingiana, a new smut species on Carex pauciflora from Beringia MARCIN PIĄTEK Department of Mycology, W. Szafer Institute of Botany, Polish Academy of Sciences, Lubicz 46, PL-31-512 Kraków, Poland e-mail: [email protected] Abstract The new smut fungus, Anthracoidea transberingiana attacking ovaries of Carex pauciflora, is described and illustrated from Beringia (Alaska and Kamchatka). The new species is compared with Anthracoidea caricis-pauciflorae infecting the same host plant species predominantly in northern Europe, from which it differs in having smaller spores, thinner spore walls, 2–3 weakly visible internal swellings and somewhat less prominent spore ornamentation. Key words: Anthracoideaceae, Cyperaceae, plant pathogens, smut fungi, Ustilaginales Introduction The few-flowered sedge Carex pauciflora Lightfoot (1777: 543) is a circumpolar species, widely distributed in arctic, boreal and montane ecosystems of North America, Europe and Asia where it occurs mostly on the Sphagnum bogs or different kinds of acidic peat soils (Chater 1980, Hultén & Fries 1986, Egorova 1999, Cochrane 2002). In northern Europe, the few-flowered sedge is rarely infected by the ovary smut Anthracoidea caricis-pauciflorae (Lehtola 1940: 127) Kukkonen (1963: 74). This smut species was also reported from two extra-European stations, namely British Colombia in North America (Kukkonen 1963) and Kamchatka in Asia (Karatygin & Azbukina 1989). In the European and world smut monographs, Vánky (1994, 2012) reported that A. caricis-pauciflorae occurs in northern Europe, northern North America and north-east Asia.

Abstract: This is the first publication dedicated to the diversity of smut fungi in Panama based on field work, the study of herbarium specimens, and references taken from literature. It includes smuts parasitizing cultivated and wild plants. The latter are mostly found in rural vegetation. Among the 24 species cited here, 14 species are recorded for the first time for Panama. One of them, Sporisorium ovarium, is observed for the first time in Central America. Entyloma spilanthis is found on the host species Acmella papposa var. macrophylla (Asteraceae) for the first time. Entyloma costaricense and Entyloma ecuadorense are considered synonyms of Entyloma compositarum and Entyloma spilanthis respectively. For the new conbination Sponsorium panamensis see note at the end of this publication. Descriptions of the species are complemented by some illustrations, a checklist, and a key.

Characterising plant pathogen communities and their environmental drivers at a national scale A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University by Andreas Makiola Lincoln University, New Zealand 2019 General abstract Plant pathogens play a critical role for global food security, conservation of natural ecosystems and future resilience and sustainability of ecosystem services in general. Thus, it is crucial to understand the large-scale processes that shape plant pathogen communities. The recent drop in DNA sequencing costs offers, for the first time, the opportunity to study multiple plant pathogens simultaneously in their naturally occurring environment effectively at large scale. In this thesis, my aims were (1) to employ next-generation sequencing (NGS) based metabarcoding for the detection and identification of plant pathogens at the ecosystem scale in New Zealand, (2) to characterise plant pathogen communities, and (3) to determine the environmental drivers of these communities. First, I investigated the suitability of NGS for the detection, identification and quantification of plant pathogens using rust fungi as a model system.
