This book was released on 2005 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quinoa (Chenopodium quinoa Willd.) is a staple grain for the indigenous people of the Andean region of South America with excellent nutritional qualities, including protein content. The objective of this study is to report on the development of fluorescence-tagged simple sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs) to (1) genetically characterize the inherent diversity of 152 accessions of C. quinoa; (2) determine to what degree the CIP-FAO collection represents the range of genetic diversity in quinoa; and (3) test four hypotheses regarding quinoa?s center of diversity, Highland and Lowland clustering patterns, origin of Lowland varieties, and the origin of domestication. Thirty-five SSR loci comprising 432 alleles ranging from 5 (QAAT10) to 28 (QAAT50) alleles per locus (mean=13) were used to survey the 152 accessions of quinoa from the USDA and CIP-FAO collections. Heterozygosity was detected in 14.25% of the accessions for SNP loci and in at least one locus for 51% of the accessions. Both UPGMA and PCA analyses partitioned the quinoa accessions into two main clusters. The first major cluster consisted of accessions from the Andean highlands of Peru, Bolivia, Ecuador, Argentina, and extreme northeastern Chile. The other main cluster contained accessions from both the Lowlands of Chile and those collected by Emigdio Ball?? The CIP-FAO collection appears to give a good representation of quinoa?s genetic diversity within these two main clusters. The significance of patterns of genetic diversity within C. quinoa is discussed.

An important strategy to overcome the challenges in providing food for the world population in a sustainable manner is through concerted efforts by crop scientists to embrace new technologies in increasing yield, quality and improving food safety while minimizing adverse environmental impact of the agricultural activities. Most of the proven molecular and genetic technologies in crop science have been tested and verified in model plants such as Arabidopsis and tomato. The technologies, when deployed on various plant species of importance for human nutrition and industrial applications, including cereals, vegetables, fruits, herbs, fibre and oil crops, face many challenges, not only due to their longer life cycle but many other physiological and environmental factors affecting yield and quality of plant products. Furthermore, major impacts on crop production due to catastrophic diseases and global climate change needs urgent and innovative solutions. Therefore a systematic approach, employing various leading-edge technologies that enable the functional elucidation of key pathway genes via ‘omics tools, genome wide association with desired phenotypes and development of cost effective and practicable molecular tools for selection, is vital. The International Conference on Crop Improvement was held to address these and other pressing issues. This volume summarizes the keynote presentations from the meeting and highlights addition discussions that are critical to crop improvement in a challenging time.

Download or read book The Quinoa Genome written by Sandra M. Schmöckel and published by Springer Nature. This book was released on 2021-02-04 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on quinoa, providing background information on its history, summarizing recent genetic and genomic advances, and offering directions for future research. Meeting the caloric and nutritional demands of our growing population will not only require increases in overall food production, but also the development of new crops that can be grown sustainably in agricultural environments that are increasingly susceptible to degradation. Quinoa is an ancient crop native to the Andean region of South America that has recently gained international attention because its seeds are high in protein, particularly in essential amino acids. Quinoa is also highly tolerant of abiotic stresses, including drought, frost and salinity. For these reasons, quinoa has the potential to help address issues of food security – a potential that was recognized when the United Nations declared 2013 the International Year of Quinoa. However, more effort is needed to improve quinoa agronomically and to understand the mechanisms of its abiotic stress tolerance; the recent development of genetic and genomic tools, including a reference genome sequence, will now help accelerate research in these areas.

Download or read book Gene Pool Diversity and Crop Improvement written by Vijay Rani Rajpal and published by Springer. This book was released on 2016-02-02 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population is estimated to reach to more than 10 billion by the year 2050. These projections pose a challenging situation for the agricultural scientists to increase crops productivity to meet the growing food demands. The unavailability and/or inaccessibility to appropriate gene pools with desired traits required to carry out genetic improvement of various crop species make this task formidable for the plant breeders. Incidentally, most of the desired genes reside in the wild genetic relatives of the crop species. Therefore, exploration and characterization of wild genetic resources of important crop species is vital for the efficient utilization of these gene pools for sustainable genetic improvements to assure food security. Further, understanding the myriad complexities of genic and genomic interactions among species, more particularly of wild relatives of crop species and/or phylogenetically distant germplasm, can provide the necessary inputs to increase the effectiveness of genetic improvement through traditional and/or genetic engineering methods. This book provides comprehensive and latest insights on the evolutionary genesis of diversity, access and its utilization in the evolution of various crop species. A comprehensive account of various crops, origin, exploitation of the primary, secondary and tertiary gene pools through breeding, biosystematical, cytogenetical and molecular phylogenetical relationships, and genetic enhancement through biotechnological interventions among others have been provided as the necessary underpinnings to consolidate information on the effective and sustainable utilization of the related genetic resources. The book stresses upon the importance of wild germplasm exploration, characterization and exploitation in the assimilation of important crop species. The book is especially intended for students and scientists working on the genetic improvement of crop species. Plant Breeders, Geneticists, Taxonomists, Molecular Biologists and Plant Biotechnologists working on crop species are going to find this book very useful.

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 Sustainable Agriculture Reviews 51 written by Praveen Guleria and published by Springer Nature. This book was released on 2021-04-12 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of climate change, pollution and food safety, the current challenge is to enhance legumes production to sustain the growing population needs by 2050. This is a daunting task because abiotic and biotic stresses are threatening the growth, survival and productivity of legumes. For instance, the productivity of legumes is documented to be reduced by 14-88% by abiotic stresses. The co-occurrence of abiotic and biotic stresses under field conditions leads to interactive stress types, thus yielding positive or negative outcomes. Legumes react using antioxidant defense, osmoregulatory adjustments, hormonal regulations and molecular mechanisms to tolerate stress. Hence, improving legume productivity requires knowledge on the sensitivity, mechanisms and approaches of stress tolerance in legumes, in order to design new crops and alternative management systems. This book presents advances on bioactive compounds, applications, effect of various stresses and biotechnology-based stress tolerance mechanisms of legumes. This is our second volume on Legume Agriculture and Biotechnology, published in the series Sustainable Agriculture Reviews.
