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
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
In North America, management of viruses in seed potatoes has primarily been done through seed certification. In last decade, the effectiveness of certification has been challenged by the reemergence of Potato virus Y (PVY). The potyvirus is transmitted by aphids in a non-persistent manner. Three major factors have led to its reemergence: i) the occurrence of PVY strains that show mild symptoms and cause tuber necrotic ringspot disease; ii) the release and popularity of potato cultivars that do not show symptoms of infection; and iii) the limited availability of resistant cultivars. These factors have resulted in higher incidence of PVY in seed potatoes and rejection of seed lots in recent years, which has an economic impact on the seed potato industry. Additionally, seed certification programs have seen an increase in the cost of PVY management. The research presented here describes the development and evaluation of tools that can improve current PVY management. I addressed the need for a more cost-efficient and flexible assay to detect potato viruses through the optimization of a chemiluminescent dot-blot immunoassay. I also evaluated the usefulness of using minitubers as seed to reduce the risk of PVY in seed propagation. I found that, compared to plants grown from conventional seed, minituber-grown plants produced lower yields, emerged and matured later, but were not more susceptible to PVY. Finally, I collaborated with breeders at the University of Wisconsin-Madison to address the need for PVY resistant commercial potato cultivars in two projects. The first project involved the application of marker-assisted selection to introduce PVY resistance genes Ryadg and Rysto into Wisconsin cultivars. The results of screening populations derived from crosses with resistant parents provided evidence of the usefulness of molecular markers for selecting PVY resistant plants and suggest that PVY resistance is not linked to undesirable traits. The second project focused on identifying and evaluating markers linked to PVY resistance gene Rychc. The results suggest that the markers developed are useful for selecting resistant plants, as well as provide evidence of the presence of a lethal factor associated with PVY susceptibility that could aid in identifying resistant individuals.

Book Description
Operational Research (OR) deals with the use of advanced analytical methods to support better decision-making. It is multidisciplinary with strong links to management science, decision science, computer science and many application areas such as engineering, manufacturing, commerce and healthcare. In the study of emergent behaviour in complex adaptive systems, Agent-based Modelling & Simulation (ABMS) is being used in many different domains such as healthcare, energy, evacuation, commerce, manufacturing and defense. This collection of articles presents a convenient introduction to ABMS with papers ranging from contemporary views to representative case studies. The OR Essentials series presents a unique cross-section of high quality research work fundamental to understanding contemporary issues and research across a range of Operational Research (OR) topics. It brings together some of the best research papers from the esteemed Operational Research Society and its associated journals, also published by Palgrave Macmillan.
