Available in PDF, EPUB and Kindle. Book excerpt: Human population is escalating at an enormous pace and is estimated to reach 9.7 billion by 2050. As a result, there will be an increase in demand for agricultural production by 60–110% between the years 2005 and 2050 at the global level; the number will be even more drastic in the developing world. Pathogens, animals, and weeds are altogether responsible for between 20 to 40 % of global agricultural productivity decrease. As such, managing disease development in plants continues to be a major strategy to ensure adequate food supply for the world. Accordingly, both the public and private sectors are moving to harness the tools and paradigms that promise resistance against pests and diseases. While the next generation of disease resistance research is progressing, maximum disease resistance traits are expected to be polygenic in nature and controlled by selective genes positioned at putative quantitative trait loci (QTLs). It has also been realized that sources of resistance are generally found in wild relatives or cultivars of lesser agronomic significance. However, introgression of disease resistance traits into commercial crop varieties typically involves many generations of backcrossing to transmit a promising genotype. Molecular marker-assisted breeding (MAB) has been found to facilitate the pre-selection of traits even prior to their expression. To date, researchers have utilized disease resistance genes (R-genes) in different crops including cereals, pulses, and oilseeds and other economically important plants, to improve productivity. Interestingly, comparison of different R genes that empower plants to resist an array of pathogens has led to the realization that the proteins encoded by these genes have numerous features in common. The above observation therefore suggests that plants may have co-evolved signal transduction pathways to adopt resistance against a wide range of divergent pathogens. A better understanding of the molecular mechanisms necessary for pathogen identification and a thorough dissection of the cellular responses to biotic stresses will certainly open new vistas for sustainable crop disease management. This book summarizes the recent advances in molecular and genetic techniques that have been successfully applied to impart disease resistance for plants and crops. It integrates the contributions from plant scientists targeting disease resistance mechanisms using molecular, genetic, and genomic approaches. This collection therefore serves as a reference source for scientists, academicians and post graduate students interested in or are actively engaged in dissecting disease resistance in plants using advanced genetic tools.
Download or read book History and the Testimony of Language written by Christopher Ehret and published by Univ of California Press. This book was released on 2011 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about history and the practical power of language to reveal historical change. Christopher Ehret offers a methodological guide to applying language evidence in historical studies. He demonstrates how these methods allow us not only to recover the histories of time periods and places poorly served by written documentation, but also to enrich our understanding of well-documented regions and eras. A leading historian as well as historical linguist of Africa, Ehret provides in-depth examples from the language phyla of Africa, arguing that his comprehensive treatment can be applied by linguistically trained historians and historical linguists working with any language and in any area of the world.
Download or read book Historical Linguistics and the Comparative Study of African Languages written by Gerrit J. Dimmendaal and published by John Benjamins Publishing. This book was released on 2011-06-08 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: This advanced historical linguistics course book deals with the historical and comparative study of African languages. The first part functions as an elementary introduction to the comparative method, involving the establishment of lexical and grammatical cognates, the reconstruction of their historical development, techniques for the subclassification of related languages, and the use of language-internal evidence, more specifically the application of internal reconstruction. Part II addresses language contact phenomena and the status of language in a wider, cultural-historical and ecological context. Part III deals with the relationship between comparative linguistics and other disciplines. In this rich course book, the author presents valuable views on a number of issues in the comparative study of African languages, more specifically concerning genetic diversity on the African continent, the status of pidginised and creolised languages, language mixing, and grammaticalisation.

Download or read book Tohellwithyou Mitro written by Kr̥shṇa Sobatī and published by Katha. This book was released on 2007 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Krishna Sobti's lively, unapologetic portrayal of a married woman who brooks no limits to her sexuality is as compelling, pertinent and provocative today as when it first shook the Hindi literary world in 1966. Katha presents another masterpiece from one of the most spirited writers of our times. Mitro Marjani was not a writer's story ... I was amazed at the surprises Mitro gave me at every turn. Brought up outside the walls of patriarchy ... Mitro is her mother's daughter who can voice her desires and get away with it. She has no inhibitions about talking of things tabooed by tradition. She really impressed me .- Krishna Sobti

Book excerpt: The 12th International Conference for Nubian Studies was held at the British Museum, London, from 1st-6th August 2010. The conference, held every four years, is the only international gathering of archaeologists and scholars from associated disciplines which considers all aspects of Sudan and southern Egypt's ancient and more recent past. The main sessions, and main papers published herein, were devoted to a consideration of the Merowe Dam Archaeological Salvage Project, its aftermath and impact. Over de previous decade this has been the major focus of archaeological activity on the Middle Nile. The dam is now complete and the reservoir is filled, drawing a line under the fieldwork component of the project. It was felt timely, therefore, in the interim to obtain an overview of what was found during the many years of intensive work and the first main paper speaker in each session sought to do just that. They were followed by reports on sites, categories of objects and more thematic papers arranged broadly by period. These highlight that, while the focus of archaeological activity still remains in the Nile Valley where there is the densest concentration of sites and also where there remains the most concentrated threat to their survival, much work is being undertaken away from the river and in some cases outside its catchment area. The role of the deserts is increasingly being appreciated while the role of the savannah and areas even further south have yet to be given the prominence that they probably deserve.
