Diversity of the Capnocheirides Rhododendri-Dominated Fungal Community in the Phyllosphere of Rhododendron Ferrugineum L
Nova Hedwigia Vol. 97 (2013) Issue 1–2, 19–53 Article Stuttgart, August 2013 Diversity of the Capnocheirides rhododendri-dominated fungal community in the phyllosphere of Rhododendron ferrugineum L. Fabienne Flessa* and Gerhard Rambold University of Bayreuth, Deptartment of Mycology, Universitätsstraße 30, 95447 Bayreuth, Germany With 3 figures and 3 tables Abstract: Individuals of Rhododendron ferrugineum at natural sites within the mountain ranges and valleys Flüela, Julier, Monstein and Grimsel (in the cantons of Graubünden and Bern, Switzerland) were analysed to determine the occurrence of pigmented epifoliar fungi in their phyllosphere. Molecular data from the fungal isolates revealed a wide range of species to be present, forming a well characterized oligospecific community, with Capnocheirides rhododendri (Mycosphaerellaceae, Capnodiales, Ascomycota) being the most frequently occurring taxon. One group of fungi was exclusively isolated from the leaf surfaces and recognized as being residential epifoliar. A second ecological group was absolutely restricted to the inner leaf tissues and considered as truly endofoliar. Members of a third group occurring in both the epifoliar and endofoliar habitats were considered to have an intermediate life habit. Members of this latter group are likely to invade the inner leaf tissues from the outside after having established a mycelium on the leaf surface. Comparison of the degree of pigmentation between cultivated strains of the strictly epifoliar and strictly endofoliar community members provided some indication that epifoliar growth is to a certain degree correlated with the ability of the fungi to develop hyphal pigmentation. The endofoliar growth is assumed to entail a complete lack or presence of a more or less weak hyphal pigmentation. -

Paskiewicz5, Richard J. Harrison6, David J. Hughes7, Thomas Wolf8, Ekaterina Shelest8, Jenny Graap1, Jan Hoffmann1, Claudia Wenzel1,13, Nadine Wöltje1, Kevin M. King9, Bruce D. L. Fitt10, Ulrich Güldener11, Anna Avrova12 and Wolfgang Knogge1* Abstract Background: The Rhynchosporium species complex consists of hemibiotrophic fungal pathogens specialized to different sweet grass species including the cereal crops barley and rye. A sexual stage has not been described, but several lines of evidence suggest the occurrence of sexual reproduction. Therefore, a comparative genomics approach was carried out to disclose the evolutionary relationship of the species and to identify genes demonstrating the potential for a sexual cycle. Furthermore, due to the evolutionary very young age of the five species currently known, this genus appears to be well-suited to address the question at the molecular level of how pathogenic fungi adapt to their hosts. Results: The genomes of the different Rhynchosporium species were sequenced, assembled and annotated using ab initio gene predictors trained on several fungal genomes as well as on Rhynchosporium expressed sequence tags. Structures of the rDNA regions and genome-wide single nucleotide polymorphisms provided a hypothesis for intra-genus evolution. Homology screening detected core meiotic genes along with most genes crucial for sexual recombination in ascomycete fungi. In addition, a large number of cell wall-degrading enzymes that is characteristic for hemibiotrophic and necrotrophic fungi infecting monocotyledonous hosts were found. -

Source of Useful Traits
Chapter 8 Source of Useful Traits Leonard W. Panella, Piergiorgio Stevanato, Ourania Pavli and George Skaracis Abstract In the late 1800s, there already was speculation that Beta maritima might provide a reservoir of resistance genes that could be utilized in sugar beet breeding. European researchers had crossed Beta maritima and sugar beet and observed many traits in the hybrid progeny. It is impossible to estimate how widely Beta maritima was used in the production of commercial varieties, because most of the germplasm exchanges were informal and are difficult to document. Often these crosses of sugar beet with sea beet germplasm contained undesirable traits, e.g., annualism, elongated crowns, fangy roots, high fiber, red pigment (in root, leaf, or petiole) and much lower sucrose production. It is believed that lack of acceptance of Beta maritima as a reservoir of genes was because most of the evaluations of the progeny were done in early generations: The reactions of the hybrids vulgaris × maritima were not impressive, and it is clear now that they were not adequately studied in the later generations. Keywords Disease resistance · Rhizomania · Cercospora · Nematodes · Drought · Salt stress · Root rot · Curly top · Virus yellows · Powdery mildew · Polymyxa betae Contrary to other species of the genus Beta, the evolutionary proximity between the sea beet and the cultivated types favors casual crosses (Hjerdin et al. 1994). Important characters of resistance to diseases, currently present in cultivated varieties, have been isolated from wild material (Table 8.1). According to several authors, Beta maritima is also an important means to increase the genetic diversity of cultivated types, now rather narrow from a domestication bottleneck and continuous selection for improve- ment of production and quality traits (Bosemark 1979; de Bock 1986; Doney 1998; L. -

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.
