The research presented in this volume reveals a pathogen on the move, with a growing global profile. While these diseases inflict ongoing and increasing crop losses on subsistence farmers, the pathogen now has significant political and economic impact in the developed world.This book, based on the 3rd International Bacterial Wilt Symposium, covers topics ranging from the basic biology of the host-pathogen interaction to applied research, designed to immediately address disease losses in the field. Contributors to the book span a broad range of applied and basic biologists. They work in all parts of the world, offering current data on sustainable low-tech disease control practices and on R. solanacearum as a model system for understanding molecular plant-microbe interactions.Bacterial Wilt Disease and the Ralstonia solanacearum Species Complex opens with two key reviews. One presents a thoughtful analysis of international collaborations on bacterial wilt research in the context of a review of literature published on the topic. The second is a global assessment of the current impact of bacterial wilt. Although there are still significant gaps in the data available, for the first time a general idea of the real impact and extent of these diseases around the world is presented.Topics covered in this resource include: epidemiology, disease management, breeding and deployment, host plant response and disease management, pathogen genetics, R. solanacearum in banana and plantains, and diversity and detection. Experts provide overviews focusing on the pressing research needs in each area. These overview chapters are intended to give the reader the best current understanding of the topic and to suggest promising directions for future research.Global Impact of R. solanacearum:R. solanacearum is a contentious topic in agricultural trade negotiations in the European Union and is subject to strict quarantine and eradication regulations in the United States. This legislation has had unforeseen economic impacts on laborers in developing nations where millions of ornamental plant cuttings are produced for the North American and European markets. In addition, reports at the 3rd International Bacterial Wilt Symposium indicated that the most rapid and alarming increases in bacterial wilt disease incidence around the world are on potatoes, bananas and plantains. More than ever, scientists who work with this pathogen must recognize that although bacterial wilt certainly can cause severe crop losses on a local scale, it also plays a complex and significant role in the worldwide agricultural matrix.

Available in PDF, EPUB and Kindle. Book excerpt: Jointly published with INRA, Paris. Bacterial wilt, caused by Ralstonia solanacearum, is a very destructive plant disease that attacks over 450 different species, including many of the most important economic crop plants. Often endemic, the bacterium transmits through the soil, penetrates the plant root system and eventually causes irreversible wilting and death. This book summarizes the current information on bacterial wilt for both the basic research community and for concerned professionals who are faced with the disease in the field, offering the latest approaches to diagnosis and control of the disease. Emphasis is placed on integrated and biologically sustainable control methods. Also presented is the most recent genetic/biochemical research exploring the interaction between the bacterium and its plant host at the molecular level.

Available in PDF, EPUB and Kindle. Book excerpt: Bacterial wilt caused by Ralstonia solanacearum limits the global production of many crops. The extensive genetic diversity of the bacterium has in recent years led to the concept of a R. solanacearum Species Complex (RSSC). Genome sequencing of over 30 representative strains of the each phylogenetic groups has broadened our knowledge of the evolution and speciation of RSSC. This enabled the identification of novel virulence-associated functions. Furthermore, a large number of studies have been carried on plants-R. solanacearum interactions and shed light on the genetics, molecular biology, and disease development. These studies have documented the infection strategies of R. solanacearum employed to cope with plant immune defenses. Although these qualitative investigations are a basis to understand the pathogenesis of R. solanacearum, they are insufficient to know whether or not plants will be diseased. These fundamental questions require a quantitative understanding of the processes responsible for the rise, dissemination and fall of the infection populations of R. solanacearum. This work pioneered the quantitative study in plant bacterial pathogens by addressing the following question: "How many R. solanacearum individuals enter from the root to establish the bacterial wilt disease in plant?" It allowed us to determine what factors control the infection dynamics of R. solanacearum within the host plant. This scientific question requires a re-examination on the life cycle of R. solanacearum and the precise characterization of the whole infection process in plant. Seven dynamical parameters were refined from five subsequent infection steps of R. solanacearum in host plant. Then, we established a mathematical model of within-host dynamics of the bacterium by the integration of these parameters. The model suggests that the whole population dynamics influences the founding population/bottleneck size of R. solanacearum. The in vivo assessment of parameters and their interactions predicted a small founding population size, around four hundred bacterial cells, which was confirmed by experimental measurements with a probabilistic approach. To understand mechanisms restricting R. solanacearum population, we further investigated impacts of bacterial virulence, plant barriers and environmental factor on the infection founding population. We showed that infection bottleneck is mainly modulated by the pathogen (virulence arsenal), the host (physical and immunity traits) and the environmental conditions (temperature).

Book excerpt: The Ralstonia solanacearum (Rs) species complex contains some of the most scientifically and economically important bacterial plant pathogens. This destructive group causes lethal bacterial wilt disease (BWD) at every level of production from small- to large-scale farming operations, affecting over 200 plant species, including the model host tomato. This remarkable pathogen's biology allows it to feast in seemingly nutrient poor environments, notably the host xylem. The results of bacterial mutagenesis and multiple forms of virulence and xylem sap growth assays demonstrated that quorum sensing specifically adapts Rs metabolism for success in the different nutritional environments of plant roots and xylem sap. The best way to control BWD is planting wilt-resistant varieties, although the mechanisms of wilt resistance are poorly understood. Inspired by previous xylem sap growth assays, we found that Rs grew less on xylem sap from the widely-used wilt-resistant tomato breeding line Hawaii7996 (H7996) than on sap from a susceptible plant. However, the Rs strain UW551, which can overcome H7996 resistance, was not inhibited by sap from H7996 plants. Future characterization led to the discovery that some Rs strains uses multiple mechanisms to overcome Hawaii7996 inhibitory xylem sap, including subverting plant defenses and degrading antimicrobial phenolic chemicals. These findings will further our understanding of biochemical responses underlying tomato resistance to BWD.Along with plant pathology, this thesis explores the scholarship in teaching and learning. The findings illuminate faculty evidence-based teaching implementation changes during a disruptive social climate and identify differences in teaching motivative for STEM faculty.

Book excerpt: This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.
