While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Pags(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. St is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

In this paper, generic names in Pucciniomycotina and Ustilaginomycotina are evaluated pleomorphic fungi based on their type species to determine which names are synonyms. Twenty-one sets of sexually and asexually taxonomy typified names in Pucciniomycotina and eight sets in Ustilaginomycotina were determined to be congeneric and protected names compete for use.

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.

    An Inventory of Fungal Diversity in Ohio Research Thesis Presented In

    An Inventory of Fungal Diversity in Ohio Research Thesis Presented in partial fulfillment of the requirements for graduation with research distinction in the undergraduate colleges of The Ohio State University by Django Grootmyers The Ohio State University April 2021 1 ABSTRACT Fungi are a large and diverse group of eukaryotic organisms that play important roles in nutrient cycling in ecosystems worldwide. Fungi are poorly documented compared to plants in Ohio despite 197 years of collecting activity, and an attempt to compile all the species of fungi known from Ohio has not been completed since 1894. This paper compiles the species of fungi currently known from Ohio based on vouchered fungal collections available in digitized form at the Mycology Collections Portal (MyCoPortal) and other online collections databases and new collections by the author. All groups of fungi are treated, including lichens and microfungi. 69,795 total records of Ohio fungi were processed, resulting in a list of 4,865 total species-level taxa. 250 of these taxa are newly reported from Ohio in this work. 229 of the taxa known from Ohio are species that were originally described from Ohio. A number of potentially novel fungal species were discovered over the course of this study and will be described in future publications. The insights gained from this work will be useful in facilitating future research on Ohio fungi, developing more comprehensive and modern guides to Ohio fungi, and beginning to investigate the possibility of fungal conservation in Ohio. INTRODUCTION Fungi are a large and very diverse group of organisms that play a variety of vital roles in natural and agricultural ecosystems: as decomposers (Lindahl, Taylor and Finlay 2002), mycorrhizal partners of plant species (Van Der Heijden et al.

    Unraveling the Mechanisms of Sr35-Based Resistance in the Wheat-Puccinia Graminis F.Sp

    Unraveling the mechanisms of Sr35-based resistance in the wheat-Puccinia graminis f.sp. tritici pathosystem by Andrés Felipe Salcedo B.Sc., Universidad del Valle, Colombia, 2003 M.Sc., University of Puerto Rico, 2011 AN ABSTRACT OF A DISSERTATION Submitted in partial fulfillment of the requirements for the degree DOCTOR OF PHILOSOPHY Department of Plant Pathology College of Agriculture KANSAS STATE UNIVERSITY Manhattan, Kansas 2018 Abstract The fungus Puccinia graminis f. sp. tritici (Pgt) is the causal agent of the wheat stem rust disease. Wheat stem rust has attracted a lot of attention after the emergence of the Ug99 race group, which at the time of its origin was virulent on most of the wheat varieties cultivated around the world. The evolution and spread of the Pgt isolates from the Ug99 race group posed a serious threat to worldwide wheat production. To mitigate the potential impact of new rust epidemics in major wheat production areas, it remains critical to identify new strategies for breeding durable resistance traits. A detailed understanding of the plant-pathogen interaction mechanisms in the wheat-Pgt pathosystem should be the foundation of these strategies. The interaction between the matching pair of resistance (R) and avirulence (Avr) genes, an important element of the plant-pathogen interactions, is described by the broadly documented gene-for- gene model. The cloning of the Sr35 gene, which confers near immunity against all isolates from the Ug99 race group provided a unique opportunity to investigate the molecular mechanisms of resistance to stem rust in wheat. The goals of the present study were: (1) to determine whether the Sr35 gene alone is sufficient for conferring resistance against Ug99, (2) to assess the Sr35 transcript levels during the time course of infection, and (3) to identify and validate the corresponding Avr gene interacting with Sr35.

    311 The Uredinales of Delaware. H. S. Jackson—Purdue University. The following account of the Uredinales of Delaware is the result of a study of the rust flora of that State begun in 1906, during the tir_:e when the writer was connected with the Delaware College and Experi- ment Station. A preliminary manuscript was prepared at that time and has since been revised and amplified at variovis tinies and finally rewrit- ten in the present form in the winter of 1916-1917. A few changes and additions have since been made to bring the notes up to date. The records include all the material in the Herbarium of the Dela- ware College Agricultural Experiment Station, together with the collec- tions made by the writer during a period of three years, and most of the collections made by the late Mr. A. Commons of Wilmington, Delaware. Mr. Commons made a very extensive collection of the Phanerogams and Fungi of the State, largely during the period from 1885 to 1895. Most of the fungi were determined by Mr. J. B. Ellis and duplicates of the specimens are now in the herbarium of the New York Botanical Garden. A manuscript list of the fungi was prepared by Mr. Commons, but never published. The writer enjoyed the privilege of a conference with Mr. Coimv.ons in 1907 £:nd was permitted to make a record of the rusts from his manu- script list. His collection was not available for consultation at the time, having been stored in boxes in a garret in Wilmington. Duplicate:; of most of the specimens, however, have been found and examined in the Ellis herbarium at the New York Botanical Garden.

THE FUNGI OF IOWA PARASITIC ON PLANTS By JOSEPH C. GILMAN AND W. ANDREW ARCHER From the Department of Botany, Iowa State College, and the Office of Mycology and Disease Survey, United States Department of Agriculture. Accepted for publication June 20, 1929. The parasitic fungi, particularly those living on plants, have been the object of investigation in Iowa from the time when G. E. Bessey first estab­ lished the Department of Botany at Iowa State College. This interest has almost become traditional with the succession -0f B. D. Halsted and L.
