Monocyclic Components for Evaluating Disease Resistance to Cercospora Arachidicola and Cercosporidium Personatum in Peanut
Monocyclic Components for Evaluating Disease Resistance to Cercospora arachidicola and Cercosporidium personatum in Peanut by Limin Gong A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 6, 2016 Keywords: monocyclic components, disease resistance Copyright 2016 by Limin Gong Approved by Kira L. Bowen, Chair, Professor of Entomology and Plant Pathology Charles Y. Chen, Associate Professor of Crop, Soil and Environmental Sciences John F. Murphy, Professor of Entomology and Plant Pathology Jeffrey J. Coleman, Assisstant Professor of Entomology and Plant Pathology ABSTRACT Cultivated peanut (Arachis hypogaea L.) is an economically important crop that is produced in the United States and throughout the world. However, there are two major fungal pathogens of cultivated peanuts, and they each contribute to substantial yield losses of 50% or greater. The pathogens of these diseases are Cercospora arachidicola which causes early leaf spot (ELS), and Cercosporidium personatum which causes late leaf spot (LLS). While fungicide treatments are fairly effective for leaf spot management, disease resistance is still the best strategy. Therefore, it is important to evaluate and compare different genotypes for their disease resistance levels. The overall goal of this study was to determine resistance levels of different peanut genotypes to ELS and LLS. The peanut genotypes (Chit P7, C1001, Exp27-1516, Flavor Runner 458, PI 268868, and GA-12Y) used in this study include two genetically modified lines (Chit P7 and C1001) that over-expresses a chitinase gene. This overall goal was addressed with three specific objectives: 1) determine suitable conditions for pathogen culture and spore production in vitro; 2) determine suitable conditions for establishing infection in the greenhouse; 3) compare ELS and LLS disease reactions of young plants to those of older plants. -

Multigene Phylogenies Reveal That Red Band Needle Blight of Pinus Is Caused by Two Distinct Species of Dothistroma, D
STUDIES IN MYCOLOGY 50: 551–565. 2004. Multigene phylogenies reveal that red band needle blight of Pinus is caused by two distinct species of Dothistroma, D. septosporum and D. pini Irene Barnes1*, Pedro W. Crous2, Brenda D. Wingfield1 and Michael J. Wingfield1 1Department of Genetics, Forestry and Agricultural Biotechnology Institute (FABI), University of Pretoria, Pretoria, South Africa, 0002; 2 Centraalbureau voor Schimmelcultures (CBS), Fungal Biodiversity Centre, P.O. Box 85167, 3508 AD Utrecht, The Netherlands *Correspondence: I. Barnes, [email protected] Abstract: The red band needle blight fungus, Dothistroma septosporum is a widely distributed pathogen of many pine species. Three morphological varieties of this pathogen have been described based on differences in conidial length. However, contro- versy exists as to whether spore size represents an adequate characteristic to distinguish between forms of D. septosporum. The aim of this investigation was to consider the phylogenetic relationships between D. septosporum isolates from different coun- tries. An additional objective was to determine whether comparisons of DNA sequence data support the morphological varie- ties recognized for this species. DNA from portions of the nuclear ribosomal internal transcribed spacer (ITS), !-tubulin and elongation factor 1- genes were sequenced and analysed for isolates from 13 different countries representing five continents. Results show that isolates of the pathogen encompass two divergent lineages representing distinct phylogenetic species. One phylogenetic species (Lineage I) is found worldwide, while the other (Lineage II), is restricted to the North-Central U.S.A. The names D. pini and D. septosporum are available for these species. The former name should apply to the phylogenetic species currently known only from the United States. -

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. -
