This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cercospora zeina, a causal pathogen of gray leaf spot (GLS) of maize, is responsible for up to 1 % of global yield losses. Previous small-scale population genetics studies have revealed that C. zeina is a highly diverse pathogen. Using microsatellite markers, we set out to determine the genetic diversity and population structure of 835 C. zeina isolates from five countries in Sub-Saharan Africa: Kenya, South Africa, Uganda, Zambia, and Zimbabwe, and to establish their evolutionary potential. Our findings revealed that populations from different farming systems exhibited partial, but significant population differentiation. Also, smallholder populations had a higher genetic diversity, number of private alleles and lower clonality than commercial populations. Country-level populations were highly diverse and structured, with migration occurring among populations. Interestingly, Zambia came out as a distinct population, with a lower genetic diversity, higher clonality and private alleles, indicative of a more recently introduced population. Our findings rejected the existing hypothesis of Durban harbor being the entry point of C. zeina into Africa, thus suggesting that the pathogen has other point(s) of entry. Additionally, signatures of cryptic sexual recombination were observed even though an attempt to induce the sexual stage in laboratory conditions was unsuccessful. We found no evidence for C. zeae-maydis, C. zeinaaÌ22́Ơ4́Øs sibling species in more than 1000 isolates collected from around Africa, thus confirming that C. zeina is the predominant species in Africa. Overall, this pathogen is a genetically well-established pathogen in Africa with its population structure being influenced by sexual recombination, migration and human activities. This study, therefore, provides a basis for effective monitoring of C. zeinaaÌ22́Ơ4́Øs dispersal and is a tool for designing more effective regional-specific management strategies to reduce the acquisition and movement of highly virulent strains that overcome host resistance or fungicide control.

Available in PDF, EPUB and Kindle. Book excerpt: From February 24 -28, 1992 an international symposium on Durability of Disease Resistance was held at the International Agricultural Centre in Wageningen, the Netherlands. The symposium, organized by the Department of Plant Breeding of Wageningen Agricultural University and the Centre for Plant Breeding and Repro duction Research, CPRO-DLO, was part of the DGIS funded programme Durable Resistance in Developing Countries. Without any form of prevention or protection nearly all crops will be seriously or even severely damaged by a range of pathogens. In modern agriculture man has been able to control many if not most pathogens using i) pesticides, ii) phyto sanitary methods such as control of seed and plant material in order to start a crop disease free, iii) agronomic measures such as crop rotation, iv) disease resis tance or combinations of these measures. Over the years the use of pesticides has increased enormously and so did the pro blems associated with pesticide use, such as environmental pollution and building of resistance and tolerance to these pesticides in the pathogens. The use of resis tance too increased strongly over the years and here too problems arose.

Download or read book Seed Borne Diseases of Agricultural Crops Detection Diagnosis Management written by Ravindra Kumar and published by Springer Nature. This book was released on 2020-05-18 with total page 860 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global population is increasing rapidly, and feeding the ever-increasing population poses a serious challenge for agriculturalists around the world. Seed is a basic and critical input in agriculture to ensure global food security. Roughly 90 percent of the crops grown all over the world are propagated by seed. However, seed can also harbour and spread pathogens, e.g. fungi, bacteria, nematodes, viruses etc., which cause devastating diseases. Seed-borne pathogens represent a major threat to crop establishment and yield. Hence, timely detection and diagnosis is a prerequisite for their effective management. The book "Seed-Borne Diseases of Agricultural Crops: Detection, Diagnosis & Management" addresses key issues related to seed-borne/transmitted diseases in various agricultural crops. Divided into 30 chapters, it offers a comprehensive compilation of papers concerning: the history of seed pathology, importance of seed-borne diseases, seed-borne diseases and quarantine, seed health testing and certification, detection and diagnosis of seed-borne diseases and their phytopathogens, host-parasite interactions during development of seed-borne diseases, diversity of seed-borne pathogens, seed-borne diseases in major agricultural crops, non-parasitic seed disorders, mechanisms of seed transmission and seed infection, storage fungi and mycotoxins, impact of seed-borne diseases on human and animal health, and management options for seed-borne diseases. We wish to thank all of the eminent researchers who contributed valuable chapters to our book, which will be immensely useful for students, researchers, academics, and all those involved in various agro-industries.

Download or read book Bambara groundnut Utilization and Future Prospects written by Victoria A. Jideani and published by Springer Nature. This book was released on 2021-09-27 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bambara groundnut (BGN) or Vigna subterranea is an extremely hardy grain legume. As it produces reasonable yields even under conditions of drought and low soil fertility, it is also a climate-smart crop. Previously underutilized, BGN is the subject of growing interest among researchers and consumers for its balanced nutritional profile. Indigenous consumers of BGN report medicinal benefits from the plant; however, such knowledge is at risk of being lost with the urbanization and changing lifestyles of younger generations. To date, there is no comprehensive resource on the Bambara groundnut, despite market demand for plant proteins around the globe. Authored by scientists who have researched and developed patents using BGN, Bambara Groundnut: Utilization and Future Prospects aims to fill this gap. The text provides in-depth coverage on breeding, food and feed utilization, medicinal benefits and future research prospects. Drawing on both indigenous knowledge and cutting-edge research, Bambara Groundnut is the first book to fully explore the potential of this remarkable crop.
