This book was released on 1964 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was explore possible associations between heterochromatic chromosome knobs and racial characteristics in maize and thus to identify chromosomal segments which contribute to racial specifity. Plants from two races widely different in knob constitution and morphological characteristics were crossed reciprocally. The resulting F1 and F2 generations were studied. Cytological observations and me measurements of the 16 characters most distinctive of the two races were on 60 f1 and 126 F2 plants. Results were statistically significant in 48 cases of association between knobs and characteristics among the 150 analyzed. In nine cases the level of significance was P- 1% and in the other 39 cases 2,5% P 10%. Signicante differences bet- ween plants with heterozygous knobs and the mean of homozygous knobbed and knobless plants are taken to mean that the condition of the knob can reflect the condition of the genes linked to it. The association of knobs and characteristics was postulated as a mechanism by which knobs are selected during the formation of races in maize.

Download or read book Maize written by Duccio Bonavia and published by Cambridge University Press. This book was released on 2013-05-13 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines one of the thorniest problems of ancient American archaeology: the origins and domestication of maize. Using a variety of scientific techniques, Duccio Bonavia explores the development of maize, its adaptation to varying climates, and its fundamental role in ancient American cultures. An appendix (by Alexander Grobman) provides the first ever comprehensive compilation of maize genetic data, correlating this data with the archaeological evidence presented throughout the book. This book provides a unique interpretation of questions of dating and evolution, supported by extensive data, following the spread of maize from South to North America, and eventually to Europe and beyond.
Download or read book Handbook of Maize written by Jeff L. Bennetzen and published by Springer Science & Business Media. This book was released on 2009-01-16 with total page 785 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is one of the world’s highest value crops, with a multibillion dollar annual contribution to agriculture. The great adaptability and high yields available for maize as a food, feed and forage crop have led to its current production on over 140 million hectares worldwide, with acreage continuing to grow at the expense of other crops. In terms of tons of cereal grain produced worldwide, maize has been number one for many years. Moreover, maize is expanding its contribution to non-food uses, including as a major source of ethanol as a fuel additive or fuel alternative in the US. In addition, maize has been at the center of the transgenic plant controversy, serving as the first food crop with released transgenic varieties. By 2008, maize will have its genome sequence released, providing the sequence of the first average-size plant genome (the four plant genomes that are now sequenced come from unusually tiny genomes) and of the most complex genome sequenced from any organism. Among plant science researchers, maize has the second largest and most productive research community, trailing only the Arabidopsis community in scale and significance. At the applied research and commercial improvement levels, maize has no peers in agriculture, and consists of thousands of contributors worthwhile. A comprehensive book on the biology of maize has not been published. The "Handbook of Maize: the Genetics and Genomics" center on the past, present and future of maize as a model for plant science research and crop improvement. The books include brief, focused chapters from the foremost maize experts and feature a succinct collection of informative images representing the maize germplasm collection.

Download or read book Histories of Maize written by John Staller and published by Routledge. This book was released on 2016-12-05 with total page 1129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize has been described as a primary catalyst to complex sociocultural development in the Americas. State of the art research on maize chronology, molecular biology, and stable carbon isotope research on ancient human diets have provided additional lines of evidence on the changing role of maize through time and space and its spread throughout the Americas. The multidisciplinary evidence from the social and biological sciences presented in this volume have generated a much more complex picture of the economic, political, and religious significance of maize. The volume also includes ethnographic research on the uses and roles of maize in indigenous cultures and a linguistic section that includes chapters on indigenous folk taxonomies and the role and meaning of maize to the development of civilization. Histories of Maize is the most comprehensive reference source on the botanical, genetic, archaeological, and anthropological aspects of ancient maize published to date. This book will appeal to a varied audience, and have no titles competiting with it because of its breadth and scope. The volume offers a single source of high quality summary information unavailable elsewhere.
Download or read book The Maize Genome written by Jeffrey Bennetzen and published by Springer. This book was released on 2018-11-24 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses advances in our understanding of the structure and function of the maize genome since publication of the original B73 reference genome in 2009, and the progress in translating this knowledge into basic biology and trait improvement. Maize is an extremely important crop, providing a large proportion of the world’s human caloric intake and animal feed, and serving as a model species for basic and applied research. The exceptionally high level of genetic diversity within maize presents opportunities and challenges in all aspects of maize genetics, from sequencing and genotyping to linking genotypes to phenotypes. Topics covered in this timely book range from (i) genome sequencing and genotyping techniques, (ii) genome features such as centromeres and epigenetic regulation, (iii) tools and resources available for trait genomics, to (iv) applications of allele mining and genomics-assisted breeding. This book is a valuable resource for researchers and students interested in maize genetics and genomics.

Download or read book The Women of the Nobel written by Massimo di Terlizzi and published by SEM - Servizi Editoriali & Multimediali. This book was released on 2014-04-16 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forty-four women. Forty-four stories of incredible lives, each different from the other, but linked by the same leitmotif of excellence, perseverance and passion. This book aims at being a homage to all the women whose revolutionary discoveries and works have forever changed the history of humankind. It is for that reason, that they received the most prestigious prize of all - the Nobel Prize. By reading these biographies, you can feel to what extent society has changed from the beginning of the twentieth century to today. You will also understand how complicated it was for women born at the turn of the century to enter higher education and to be considered by their male colleagues. Unfortunately, in many fields, this attitude is still present and stronger than ever. Proportionally, only a small percentage of women have received the Swedish medal, a sign that the path to gender equality is still long. Many of them had to fight to establish themselves and make their talent known, often going against their families who saw them exclusively as wives and mothers. But they believed in themselves, had a dream, and with determination overcame every difficulty. Notwithstanding their work, all of these women, scientists, writers, organizers and spokeswomen demonstrate that with perseverance and an openness towards others, you can get where you want. As the great Rita Levi-Montalcini (Nobel Prize in Medicine) said, "The key to human existence is not love, but curiosity".
Download or read book Darwin s Harvest written by Timothy J. Motley and published by Columbia University Press. This book was released on 2006-01-04 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin's Harvest addresses concerns that we are losing the diversity of crop plants that provide food for most of the world. With contributions from evolutionary biologists, geneticists, agronomists, molecular biologists, and anthropologists, this collection discusses how economic development, loss of heirloom varieties and wild ancestors, and modern agricultural techniques have endangered the genetic diversity needed to keep agricultural crops vital and capable of adaptation. Drawing on the most up-to-date data, the contributors review the utilization of molecular techniques to understand crop evolution. They explore current research on various crop plants of both temperate and tropical origin, including maize, sunflower, avocado, sugarcane, and wheat. The chapters in Darwin's Harvest also provide solid background for understanding many recent discoveries concerning the origins of crops and the influence of human migration and farming practices on the genetics of our modern foods.
