Preface The study of fungal biotechnology is proceeding at an unprecedented rate with an array of new tools to generate a wealth of disciplines and subdisciplines. By means of modern biotechnology, fungi have justified their practical application to varied domains of human enterprise, and thus promise considerable potential in the agricultural, food, and environmental spheres. The successful application of fungal biotechnological processes in these areas requires the integration of a number of scientific disciplines and technologies. These may include subjects as diverse as agronomy, chemistry, genetic manipulation, and process engineering. The practical use of newer techniques such as genetic recombination, bioinformatics, and robotics has revolutionized modern biotechnology-based agri-food industries, and created the enormous range of possible applications of fungi. Tremendous biodiversity of agriculturally important fungi exists—the benefit of which is not fully harnessed. The level of technology required to take full advantage may range from the simple introduction of a single fungus in biocontrol processes to the extensive manipulation of the organism that facilitates overproduction of a particular enzyme or metabolite. In modern agri-industry, fungi offer many established beneficial roles, particularly as biofertilizers, mycorrhizae, and biocontrol agents of pathogens, pests, and weeds. As pathogens, fungi represent a heavy negative impact on human health, agriculture, and environment. In agriculture, annual crop losses by phytopathogenic fungi in the field and also during post- harvest exceed 200 billion Euros, and in the United States alone, over $600 million are spent annually on agricultural fungicides. The balance of beneficial and detrimental effects is reflected in many other areas of agriculture and horticulture. Fungi that inhabit tropical or temperate soils, as mycorrhiza, endophytes, phytopathogens, entomopathogens, or simple saprophytes, are significant resources in transformation of biological matter, and they offer many bioproducts including secondary metabolites, antibiotics, and catabolic enzymes of enormous potential. The world has won a crucial battle in the area of food security, but the war is still on. A total of 800 million people—that is, one of every six persons in the developing world—do not have access to food. One-third of all pre–school-age children in the developing countries face food insecurity. In the food and feed arena, fungi are historically important as mushrooms and fermented foods and in baking and brewing. Such roles are supplemented by the provision of fungi to offer food processing enzymes and additives, and more recently the development of protein-based foodstuffs from filamentous fungi. On the detrimental side, fungi cause extensive spoilage of stored and processed foodstuff. Through direct pathogenesis and biodeterioration of foods and other agricultural commodities, fungi cause considerable economic consequences as well. In these cases, techniques developed from biochemistry and molecular biology can be deployed to analyze the relevant processes, and to evolve tools for the detection, characterization, and tracking of the organisms involved. Although such endeavors may seem rather far removed from the traditional definition of fungal biotechnology, the information derived can be pivotal in understanding the underlying intricate processes, and arriving at suitable control measures. The utilization of fungi in the environment is a more recent development, and can have particular association with both food and agriculture, with fungal remediation of land having implications for biofertilizers, mycorrhizae, and food crop Copyright 2004 by Marcel Dekker, Inc. All Rights Reserved. development, among many other considerations. The degradative activities of fungi have also been harnessed in programs related to bioremediation of contaminated land, treatment of industrial wastes, and biotransformation of specific compounds. Many of the applications of fungal biotechnology in these areas rely not on identifying new activities but in harnessing and expanding roles that the fungi undertake normally in the environment. Several books on the role of fungi in agricultural, food, and environmental applications have appeared since the 1990s. However, subjects relating to these areas are so broad that no single book can provide all the available information. Consequently, this book complements the others by providing valuable information that is not available elsewhere. The book encompasses a broad range of information on biotechnological potential of entomopathogenic fungi, ergot alkaloids, fungi in disease control, the development of mycoherbicides, control of nematodes, control of plant disease, strategies for controlling vegetable and fruit crops, mycotoxigenic fungi, development of biofungicides, production of edible fungi, fermented foods, and high-value products such as mycoprotein, yeasts in the wine industry, the role of fungi in

Date: December 2018 Copyright © 2018 Stellenbosch University All rights reserved i Stellenbosch University https://scholar.sun.ac.za Abstract Alien grasses have caused major impacts in their introduced ranges, including transforming natural ecosystems and reducing agricultural yields. This is clearly of concern for South Africa. However, alien grass impacts in South Africa are largely unknown. This makes prioritising them for management difficult. In this thesis, I investigated the negative environmental and socio-economic impacts of 58 alien grasses occurring in South Africa from 352 published literature sources, the mechanisms through which they cause impacts, and the magnitudes of those impacts across different habitats and regions. Through this assessment, I ranked alien grasses based on their maximum recorded impact. Cortaderia sellonoana had the highest overall impact score, followed by Arundo donax, Avena fatua, Elymus repens, and Festuca arundinacea.

The emergence of cereal fungal diseases and the incidence of leaf spot diseases in Finland Marja Jalli, Pauliina Laitinen and Satu Latvala MTT Agrifood Research Finland, Plant Production Research, FI-31600 Jokioinen, Finland, email: [email protected] Fungal plant pathogens causing cereal diseases in Finland have been studied by a literature survey, and a field survey of cereal leaf spot diseases conducted in 2009. Fifty-seven cereal fungal diseases have been identified in Finland. The first available references on different cereal fungal pathogens were published in 1868 and the most recent reports are on the emergence of Ramularia collo-cygni and Fusarium langsethiae in 2001. The incidence of cereal leaf spot diseases has increased during the last 40 years. Based on the field survey done in 2009 in Finland, Pyrenophora teres was present in 86%, Cochliobolus sativus in 90% and Rhynchosporium secalis in 52% of the investigated barley fields.Mycosphaerella graminicola was identi- fied for the first time in Finnish spring wheat fields, being present in 6% of the studied fields.Stagonospora nodorum was present in 98% and Pyrenophora tritici-repentis in 94% of spring wheat fields. Oat fields had the fewest fungal diseases. Pyrenophora chaetomioides was present in 63% and Cochliobolus sativus in 25% of the oat fields studied.

These include the uplands of the Clees, Stiperstones and Long Mynd with their associated heath land, forested land such as the Forest of Wyre and the Mortimer Forest, the lowland bogs and meres in the north of the county, and agricultural land scattered with small woodlands and copses. This diversity makes Shropshire unique. The Shropshire Fungus Group has been in existence for 18 years. (Inaugural meeting 6th December 1992. The aim was to produce a fungus flora for the county. This aim has not yet been realised for a number of reasons, chief amongst these are manpower and cost. The group has however collected many records by trawling the archives, contributions from interested individuals/groups, and by field meetings. It is these records that are published here. The first Shropshire checklist was published in 1997. Many more records have now been added and nearly 40,000 of these have now been added to the national British Mycological Society’s database, the Fungus Record Database for Britain and Ireland (FRDBI). During this ten year period molecular biology, i.e. DNA analysis has been applied to fungal classification.

Nematode sampling Unlike some pests and diseases, nematodes cannot be monitored by observation in the field. Nematodes must be extracted for microscopic examination in the laboratory. Nematodes can be collected by sampling soil and plant materials. There is no problem in finding nematodes, but getting the species and numbers you want may be trickier. In general, natural and undisturbed habitats will yield greater diversity and more slow-growing nematode species, while temporary and/or disturbed habitats will yield fewer and fast- multiplying species. Sampling considerations Getting nematodes in a sample that truly represent the underlying population at a given time requires due attention to sample size and depth, time and pattern of sampling, and handling and storage of samples.

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.
