Available in PDF, EPUB and Kindle. Book excerpt: The bacterial wilt diseases caused by members of the Ralstonia solanacearum species complex have never been more important. 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.

Download or read book Peppers written by Vincent M. Russo and published by CABI. This book was released on 2012 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The group of plants called pepper is diverse, containing plants that contribute to the fresh and processed markets and are also used in pharmaceuticals and other non-food commercial products. Peppers developed in tropical regions, but are grown and used in every country where they can be grown and in countries where production is difficult. The book examines peppers from historical, genetic, physiological, production, and post-harvest standpoints following the development of the cultivated crop from the wild type. The diverse examples of pod types that have been developed and their variation in pungency are examined. Production methods, including the importance of fertilization and irrigation are discussed, as are the constraints on production, including pests, pathogens and weeds. Harvesting methods and the post-harvest challenges and opportunities, which exist at a level not found for other crops, will be explored.

Download or read book The Wild Solanums Genomes written by Domenico Carputo and published by Springer Nature. This book was released on 2021-09-21 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the latest information on the organization of genomes in wild Solanum species and emphasizes how this information is yielding direct outcomes in the fields of molecular breeding, as well as a better understanding of both the patterns and processes of evolution. Cultivated Solanums, such as potato, tomato, and pepper, possess a high number of wild relatives that are of great importance for practical breeding and evolutionary studies. Their germplasm is often characterized by allelic diversity, as well as genes that are lacking in the cultivated species. Wild Solanums have not been fully exploited by breeders. This is mainly due to the lack of information regarding their genetics and genomics. However, the genome of important cultivated Solanaceae such as potato, tomato, eggplant, and pepper has already been sequenced. On the heels of these recent developments, wild Solanum genomes are now becoming available, opening an exciting new era for both basic research and varietal development in the Solanaceae.

Download or read book Solanaceae Biology and Systematics written by William G. D'Arcy and published by Columbia University Press. This book was released on 1986 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the puzzling phenomenon of new veiling practices among lower middle class women in Cairo, Egypt. Although these women are part of a modernizing middle class, they also voluntarily adopt a traditional symbol of female subordination. How can this paradox be explained? An explanation emerges which reconceptualizes what appears to be reactionary behavior as a new style of political struggle--as accommodating protest. These women, most of them clerical workers in the large government bureaucracy, are ambivalent about working outside the home, considering it a change which brings new burdens as well as some important benefits. At the same time they realize that leaving home and family is creating an intolerable situation of the erosion of their social status and the loss of their traditional identity. The new veiling expresses women's protest against this. MacLeod argues that the symbolism of the new veiling emerges from this tense subcultural dilemma, involving elements of both resistance and acquiescence.

Download or read book Metabolic Analyses of Ralstonia Solanacearum During Plant Pathogenesis written by Tiffany Marie Lowe-Power and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bacterial wilt pathogen Ralstonia solanacearum infects host plants through the roots and then systemically colonizes the xylem vessels that transport water and minerals from the roots to shoots. Although xylem sap is dilute and nutrient poor, R. solanacearum thrives in xylem vessels and grows to over 10^9 CFU /g stem. The focus of my thesis research was to investigate metabolic adaptations that enable R. solanacearum success in plant hosts. A previous transcriptomic study found that in tomato xylem, R. solanacearum expresses many catabolic pathways that may contribute to R. solanacearum growth in the xylem, including two pathways that degrade the plant phenolic metabolites, hydroxycinnamic acids and salicylic acid. Hydroxycinnamic acids are plant phenolics that are directly antimicrobial and are also precursors of higher phenolics. To study the role of hydroxycinnamic acid degradation, I created an R. solanacearum mutant lacking the feruloyl-CoA synthase (fcs) that cannot degrade hydroxycinnamic acids. In vitro and in planta experiments with this mutant revealed that hydroxycinnamic acid degradation protected R. solanacearum from the toxicity of two hydroxycinnamic acids, caffeic acid and p-coumaric acid. Further, this catabolic capacity allowed the pathogen to grow on these two metabolites, as well as on the less-toxic ferulic acid. The fcs mutant had delayed growth in tomato roots, which moderately reduced its virulence on tomato plants. Salicylic acid (SA) is a plant defense hormone that primes plants to resist R. solanacearum. I found that expression of the SA degradation pathway was induced by SA itself but not by the pathway intermediate gentisic acid. To determine the role of SA degradation in bacterial wilt disease, I created R. solanacearum mutants that lacked either the first step in SA degradation (nagGH) or the entire pathway (nagAaGHAbIKL). Studies with these mutants demonstrated that SA degradation allowed R. solanacearum to grow on SA, protected the pathogen from SA toxicity, and contributed to R. solanacearum virulence on tobacco but not on tomato plants, which use gentisic acid as a defense signal. My final project used an untargeted metabolomics approach to understand how bacterial wilt disease changes xylem chemistry. I found that bacterial wilt disease increases concentrations of at least eight xylem nutrients that enabled R. solanacearum to grow better in ex vivo sap from infected plants than in sap from healthy plants. This helps explain the rapid growth of this pathogen in host xylem tissue. Second, my work revealed a novel R. solanacearum metabolic virulence strategy: the bacterium produces abundant quantities of the polyamine putrescine in the xylem. Applying exogenous putrescine to tomato plants before inoculation accelerated bacterial growth, bacterial spread, and wilt disease progression. Exogenous putrescine, which is not a bacterial nutrient, facilitated success of diverse R. solanacearum strains on tobacco and three different tomato lines. Moreover, putrescine was also increased in xylem sap of tomato plants infected with a fungal vascular pathogen, suggesting that this polyamine may play a general role in wilt disease development.
