Download or read book Origin of Cultivated Rice written by H.-I. Oka and published by Elsevier Science. This book was released on 1988-01-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to up-date our present understanding of the origin of cultivated rice and in doing so involves different disciplines of biology and the archaeological-historical sciences. Various recent discoveries are reviewed and questions posed for further consideration by the reader.The book covers a wide range of studies on problems relative to the origin of cultivated rice, placing emphasis on ecological and genetical aspects. Comparisons are made between two cultivated rice species, independently evolved in Asia and Africa from respective wild progenitors. Phenomena are observed during mixed planting and hybrids discussed. Detailed information is presented about Asian common wild rice, thought to be the ancestor of common rice. The dynamics of domestication are considered with regard to hybridization, selection, formation of weedy types and the accumulation of genetic diversity. Also included are recent archaeological findings in relation to the beginnings of rice culture, leading to the hypothesis of diffused origins. Cultivars of common rice fall into one of two types called Indica and Japonica. The dynamics of differentiation are discussed, giving evidence and different hypotheses. Information on the genetic bases and functions of various reproductive barriers found between the cultivated and wild taxa is presented and discussed. The practical aspects of crop-evolutionary studies concerned with the breeding phylosophy and germplasm conservation are briefly commented on and arguments for rediversification of crop germplasm and conservation of the environment given.Senior scientists and post-graduate students interested in rice genetics, crop evolution, and related sciences will find this book invaluable.
Download or read book Black Rice written by Judith A. Carney and published by Harvard University Press. This book was released on 2009-07-01 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few Americans identify slavery with the cultivation of rice, yet rice was a major plantation crop during the first three centuries of settlement in the Americas. Rice accompanied African slaves across the Middle Passage throughout the New World to Brazil, the Caribbean, and the southern United States. By the middle of the eighteenth century, rice plantations in South Carolina and the black slaves who worked them had created one of the most profitable economies in the world. Black Rice tells the story of the true provenance of rice in the Americas. It establishes, through agricultural and historical evidence, the vital significance of rice in West African society for a millennium before Europeans arrived and the slave trade began. The standard belief that Europeans introduced rice to West Africa and then brought the knowledge of its cultivation to the Americas is a fundamental fallacy, one which succeeds in effacing the origins of the crop and the role of Africans and African-American slaves in transferring the seed, the cultivation skills, and the cultural practices necessary for establishing it in the New World. In this vivid interpretation of rice and slaves in the Atlantic world, Judith Carney reveals how racism has shaped our historical memory and neglected this critical African contribution to the making of the Americas.

Download or read book Lost Crops of Africa written by National Research Council and published by National Academies Press. This book was released on 1996-02-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scenes of starvation have drawn the world's attention to Africa's agricultural and environmental crisis. Some observers question whether this continent can ever hope to feed its growing population. Yet there is an overlooked food resource in sub-Saharan Africa that has vast potential: native food plants. When experts were asked to nominate African food plants for inclusion in a new book, a list of 30 species grew quickly to hundreds. All in all, Africa has more than 2,000 native grains and fruitsâ€""lost" species due for rediscovery and exploitation. This volume focuses on native cereals, including: African rice, reserved until recently as a luxury food for religious rituals. Finger millet, neglected internationally although it is a staple for millions. Fonio (acha), probably the oldest African cereal and sometimes called "hungry rice." Pearl millet, a widely used grain that still holds great untapped potential. Sorghum, with prospects for making the twenty-first century the "century of sorghum." Tef, in many ways ideal but only now enjoying budding commercial production. Other cultivated and wild grains. This readable and engaging book dispels myths, often based on Western bias, about the nutritional value, flavor, and yield of these African grains. Designed as a tool for economic development, the volume is organized with increasing levels of detail to meet the needs of both lay and professional readers. The authors present the available information on where and how each grain is grown, harvested, and processed, and they list its benefits and limitations as a food source. The authors describe "next steps" for increasing the use of each grain, outline research needs, and address issues in building commercial production. Sidebars cover such interesting points as the potential use of gene mapping and other "high-tech" agricultural techniques on these grains. This fact-filled volume will be of great interest to agricultural experts, entrepreneurs, researchers, and individuals concerned about restoring food production, environmental health, and economic opportunity in sub-Saharan Africa.

Download or read book The Impact of Short Interspersed Elements SINEs on the Host Genome written by Richard J. Maraia and published by Springer. This book was released on 1995-07-11 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about Short Interspersed Elements (SINEs), the homologous repetitive sequences that inhabit complex genomes. The nearly one million Alu elements interspersed in human DNA are well known to genetics researchers because of their propensity for de novo insertion into active genes. SINEs represent a complex potential of regulatory information and provide genetic variability to their host-species yet they remain enigmatic with regard to function at the cellular level. This volume catalogs our current knowledge and understanding of these elements and attempts to illuminate their biologic roles. It provides insights from disciplines such as gene regulation, cell biology, human heredity, population biology, epigenetics and evolution. Each chapter provides an examination of SINEs from a unique perspective.

Download or read book Broadening the Genetic Base of Grain Cereals written by Mohar Singh and published by Springer. This book was released on 2016-09-13 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers comprehensive coverage of important grain cereals including their origin and distribution, crop gene pool, level of diversity, production constraints, traits of importance for genetic base widening, crop improvement methodologies, genome mapping, genomics for breeding, and future strategies. The chapters, contributed by eminent crop researchers from around the world, provide rare insights into the crop-specific constraints and prospects drawing from their substantial experience. As such, the book offers an essential source of information for grain cereals scientists, teachers, students, policy planners and developmental experts alike. Grain cereals, which comprise rice, wheat, maize, barley, oats, sorghum and millets, are members of the grass family. These crops are vital to human nutrition, thanks to their roles as staple food crops in different parts of the globe. Some of them are rich sources of carbohydrates, which provide energy, while others are important sources of minerals, vitamins and proteins, in addition to their medicinal properties. In most cereals, the existing variability among elite germplasm has been exploited to attain a desirable level of productivity. However, to make further breakthroughs in enhancing yield and improving stability in future crop cultivars, new sources of genes/alleles need to be identified in wild/weedy species and incorporated into the cultivated varieties. Though there have been many publications on various aspects of grain cereal improvement in the recent past, to date this essential information has remained scattered among different periodicals.
