Book Description
Potato virus Y (PVY) infects a wide host range mainly within the Solanaceae and is distributed worldwide. PVY is transmitted by more than 40 aphid species in a non persistent manner. Isolates of the PVY species are highly variable at biological, serological and molecular levels. Epidemiological studies have highlighted the emergence of distinct potato PVY variants able to induce necroses on potato tubers. Due to the lack of efficient resistance to PVY isolates inducing necrotic symptoms in cultivated varieties and the plant-to-plant transmission of isolates through the daughter tubers, PVY has become the most economically important virus for the potato industry. The review offers an overview of several decades of research on PVY but also focuses on the latest data obtained by expert on PVY worldwide on the biological characteristics of PVY, interactions between aphids-hosts, its evolution and management. Identified knowledge gaps to understand further PVY biology will be discussed.

Book Description
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.

Book Description
This book offers a comprehensive guide to the identification, detection, characterization, classification and management of plant pathogens and other beneficial microbes in agriculture. The science of plant pathology is a dynamic field and, given the growing interest in sustainable agricultural practices, plant disease management has also gained importance. Further, there has been a shift from traditional chemical-based methods to eco-friendly integrated disease management strategies with a greater focus on bio-control and other eco-friendly technologies. This book provides a comprehensive and timely account of latest concepts and advances in the field of plant pathology, including detection and diagnosis, host resistance, disease forecasting and plant biotechnological approaches. Accordingly, it will be of great interest to academics and all stakeholders working in the fields of plant pathology, microbiology, biotechnology, plant breeding, and other life sciences.

Book Description
This book is a comprehensive up-to-date treatise that includesinformation on virus-, viroid- and phytoplasma-induced potatodiseases. The chapters of this book were written by internationallywell-known experts and include novel techniques of detection, virusisolation, transmission and epidemiology of the pathogens, as well astheir control by rapid propagation of the virus-tested clones, breeding for resistance by conventional and biotechnological methodsand implementation of certification schemes.Also included are chapters on the botanical characteristics andeconomic importance of the potato, main cultivars, historicalperspectives and emerging viruses in relation to control proceduresand regulations.This book will be of major value to all those interested in potatoes -researchers and students, general practitioners, seed potato growers, tissue culture laboratories, inspection services and regulatoryauthorities; and should attract audiences from all potato growingareas: US, Europe, South America, Russia, India and China.

Book Description
Potato viruses cause significant potato yield loss world wide. It is important to understand the nature of the potato virus populations present in a geographical region in order to develop appropriate control strategies. A wide-ranging survey of potato viruses in potatoes being grown in the northeastern USA had never been done. A survey of six potato viruses, Potato virus A (PVA), Potato virus M (PVM), Potato virus S (PVS), Potato virus X (PVX), Potato virus Y (PVY), and Potato leafroll virus (PLRV), was conducted in New York and Maine during 2002 and 2003. Leaf samples were tested by ELISA and PVY-positive samples were further tested to determine if a necrotic strain of PVY (PVYN, PVYN:O, or PVYNTN) was present. In both years, PVY and PVS were identified in a majority of the samples, and mixed infections predominated in 83% of the symptomatic leaves in 2002. Of the total 394 PVY-positive samples, three reacted with monoclonal antibody (MAb) 1F5 and caused veinal necrosis (VN) in tobacco. Two of these isolates caused tuber necrosis in the potato cv. Yukon Gold. Three PVY isolates reacted with MAb 1F5 but did not cause VN in tobacco, and two caused VN but did not react with MAb 1F5. Two of the necrotic PVY isolates collected, along with a PVYO isolate, were used to conduct multi-year experiments to determine the impact of PVY strain, potato cultivar, and time of infection on marketable yield and tuber infection efficiency. It was found that final disease incidence in the field could not be used to predict tuber infection, as inoculated plants testing negative in the field produced infected tubers. PVY infection decreased marketable yield, but yield was dependent on the potato cultivar and inoculation time. PVY infected between 25 and 100% of the marketable tubers. Our results suggest that, compared with other isolates, necrotic strains of PVY might be less effectively removed in seed potato production systems and this may explain the emergence of necrotic strains.
