Download or read book The Potato Crop written by Hugo Campos and published by Springer Nature. This book was released on 2019-12-03 with total page 524 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Viroids and Satellites describes plant diseases and their causal agents while also addressing the economic impact of these diseases. The book discusses various strategies for state-of-the-art methods for the detection and control of pathogens in their infected hosts and provides pivotal information from the discovery of viroids through the analysis of their molecular and biological properties, to viroid pathogenesis, host interactions, and RNA silencing pathways. Students, researchers and regulators will find this to be a comprehensive resource on the topics presented. - Provides coverage of the basic biological properties of disease, along with applied knowledge - Features economic impacts, transmission, geographical distribution, epidemiology, detection, and control within each chapter - Organizes viroid diseases by viroid taxonomy and viroid species

Download or read book Phytoplasmas Plant Pathogenic Bacteria I written by G.P. Rao and published by Springer. This book was released on 2018-08-02 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytoplasma-associated diseases are a major limiting factor to quality and productivity of many ornamentals, horticultural and other economically important agriculture crops worldwide. Annual losses due to phytoplasma diseases in many crops vary, but under the pathogen favorable conditions they always lead to disastrous consequences to farming community. As there is no effective cure for phytoplasma diseases, the management options emphasize on their exclusion, minimizing their spread by insect vectors and propagation materials and on development of host plant resistance. The phytoplasma associated plant diseases have a history of more than 50 years. Phytoplasmas have undoubtedly infected plants and cause diseases for centuries before they are described and proven to be the causal agents. But important progress related to identification of phytoplasmas only began after 1980’s. Phytoplasmas have emerged as the most serious constraints in the production of several crops all around the world during last four decades. Phytoplasmas constitute a major limiting factor to quality and productivity of cereals, horticultural, ornamentals and many other economically important crops all over the world. Annual losses due to phytoplasma diseases may vary, but under the pathogen favorable condition, phytoplasma disease may lead to disastrous consequences for farming and industry community. The scientific literature concerning phytoplasma occurrence, characterization, diagnosis, detection, and management is growing at a fast pace. Significant advancement in the last decades on diagnostic, biological and molecular properties, epidemiology, host-pathogen-insect interactions as well as management of phytoplasmas has been made. Till date, no authentic compilation is available to know the progress of phytoplasmas characterization major crops all over the world. The planned book will compile all the updated information available information on phytoplasmas by distinguished experts in the form of edited book entitled “Characterization and epidemiology of phytoplasma associated diseases”. The book covers recent and update information on emerging and re-emerging phytoplasma diseases affecting important crops in tropics and subtropics. It provides comprehensive information on disease distribution, occurrence, and identification of the phytoplasmas including the recent approaches for diagnostics, transmission, and information about losses and geographical distribution along with and management aspects. This volume contains 11-12 chapters contributed by the experienced and recognized experts working on different group of phytoplasmas affecting major crops all over the world. The information on various topics is at advanced as well as comprehensive level and provides the period wise developments of phytoplasma research. The book covers major chapters on an up to date progress of phytoplasma research, and then phytoplasma diseases associated with vegetable, pulse, oils crops, cereals, sugar crops, fruit crops, ornamentals, medicinal plants, palms species, forest tress and weeds. We have covered historical background, geographical distribution, identification and characterization, genetic diversity, host pathogen interaction and management aspects of important phytoplasma diseases infecting our major agricultural crops. The information on various topics is advanced as well as comprehensive, and provides thought provoking ideas for planning novel research ideas for future. This book will be useful to everyone interested in mollicutes, phytoplasma, spiroplasmas, plant pathology, disease control and plant biology and serve as an exhaustive and up-to-date compendium of references on various aspects of different groups of phytoplasmas affecting important crops worldwide.

Download or read book Seed borne plant virus diseases written by K. Subramanya Sastry and published by Springer Science & Business Media. This book was released on 2013-01-05 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seeds provide an efficient means in disseminating plant virus and viroid diseases. The success of modern agriculture depends on pathogen free seed with high yielding character and in turn disease management. There is a serious scientific concern about the transmission of plant viruses sexually through seed and asexually through plant propagules. The present book provides the latest information along with the total list of seed transmitted virus and viroid diseases at global level including, the yield losses, diagnostic techniques, mechanism of seed transmission, epidemiology and virus disease management aspects. Additional information is also provided on the transmission of plant virus and virus-like diseases through vegetative propagules. It is also well known that seed transmitted viruses are introduced into new countries and continents during large-scale traffic movements through infected germplasm and plant propogules. The latest diagnostic molecular techniques in different virus-host combinations along with disease management measures have been included. The book shall be a good reference source and also a text book to the research scientists, teachers, students of plant pathology, agriculture, horticulture, life sciences, green house managers, professional entrepreneurs, persons involved in quarantines and seed companies. This book has several important features of seed transmitted virus diseases and is a good informative source and thus deserves a place in almost all university libraries, seed companies and research organizations.
