Download or read book Disease Resistance in Crop Plants written by Shabir Hussain Wani and published by Springer. This book was released on 2019-07-24 with total page 314 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Among the Horticultural Crops, Fruits and Vegetables (FV) are of primary - portance as the key source of essential components in an adequate and balanced human diet. FV have supported largely the daily food requirement of mankind since ages and even before man learned to grow cereal crops systematically. Over the years, growing FV has been the mainstay of rural economy and has emerged as an indispensable part of agriculture world over, offering farmers a wide range of crops in varied topography and climate. In certain parts of the world, FV are the major dietary staple. Apart from being a rich source of vitamins and minerals, this sector also contributes significantly in economy of the region or the nation. The increased income from per unit area of FV is far ahead and can not be compared with that of cereal crops. A recent survey by the Economist revealed that the world population has - creased by 90 % in the past 40 years while food production has increased only by 25 % per head. With an additional 1. 5 billion mouth to feed by 2020, farmers worldwide have to produce 39 % more. Looking at the load of the future food requirement, the global increased production of FV during last few years has absorbed the additional food requirement and accordingly the eating habits are also changing and shifting - wards more consumption of these commodities worldwide.

Available in PDF, EPUB and Kindle. Book excerpt: Grain legumes play significant and diverse role in the farming systems and provide nutrition security to the largely vegetarian and relatively poorer people around the world. These are ideal crops for achieving three simultaneous developmental goals viz. reducing poverty, improving human health and nutrition and enhancing ecosystem resilience. Globally, grain legumes are the second most important crop group next only to cereals but a large proportion of area of it is under rainfed-low input systems as compared to cereals contributing to lower yields. The other important factor responsible for reduced yield in grain legumes is the narrow genetic base of the present day pulse varieties. In order to break the yield barriers of these cultivars, new sources of genes/ alleles need to be identified and suitably incorporated into the adapted background. The information on various aspects of grain legume improvement although has been considerable in the recent past, these information are highly scattered and not available at one place. The present book consists of comprehensive and latest crop-wise information on important grain legumes of the world including their distribution, gene pool, systematics, status of genetic and genomic resources, production constraints, traits of importance, crop improvement methodologies - both conventional as well as contemporary and future strategies to be adopted for comprehensive grain legume improvement in various agro-ecological target areas of the globe. The chapters have been contributed by eminent crop experts from across the world engaged in research in their respective crops for the past several years thus providing a rare insight into the crop specific constraints and prospects drawing from their rich overall experience. The book therefore will be a useful source of information to the grain legume researchers, students, policy planners and developmental experts alike.

Download or read book Air Pollution and Ecosystems written by P. Mathy and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the concluding session of the symposium "Acid Deposition, a Challenge for Europe" held in Karlsruhe in September 1983, Dr. GINJAAR, the former Minister of Health and Environmental Protection of the Netherlands, emphasised the need for setting up a concerted research programme including the effects of air pollution on terrestrial and aquatic ecosystems. The Council of Ministers of the European Community in 1984 adopted a revision of the 3rd Community Programme on Environment comprising contract research and concerted action in the field of the effects of air pollution in eco systems. These research areas were also introduced in the 4th R-D Community Programme on Environment, adopted by the Council of Ministers in 1986 and are subject again to contract research and concerted action. The Commission of the European Community is very concerned to increase the effectiveness of researcn projects carried out within the national programmes, and those undertaken at the Community level. The Commission tends to develop an integrated scientific approach, including not only the physico-chemical behaviour, the transport and the deposition of airborne pollutants but also the effects of these pollutants, in particular on living organisms and ecosystems. With regard to the specific issue of the effects, the Commission is trying to develop and strengthen a multi-disciplinary approach associating biologists, pathologists, eco physiologists, and specialists of soil sciences, within the concerted action, as well as within coordinated research projects.

Download or read book Grain Legumes written by Antonio M. De Ron and published by Springer. This book was released on 2015-08-27 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​​​This book is devoted to grain legumes and include eight chapters devoted to the breeding of specific grain legume crops and five general chapters dealing with important topics which are common to most of the species in focus. Soybean is not included in the book as it is commonly considered an oil crop more than a grain legume and is included in the Oil Crops Volume of the Handbook of Plant Breeding.​Legume species belong to the Fabaceae family and are characterized by their fruit, usually called pod. Several species of this family were domesticated by humans, such as soybean, common bean, faba bean, pea, chickpea, lentil, peanut, or cowpea. Some of these species are of great relevance as human and animal food. Food legumes are consumed either by their immature pod or their dry seeds, which have a high protein content. Globally, grain legumes are the most relevant source of plant protein, especially in many countries of Africa and Latin America, but there are some constraints in their production, such as a poor adaptation, pest and diseases and unstable yield. Current research trends in Legumes are focused on new methodologies involving genetic and omic studies, as well as new approaches to the genetic improvement of these species, including the relationships with their symbiotic rhizobia.

This book was released on 2008-06-12 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigations on various aspects of plant-pathogen interactions have the ultimate aim of providing information that may be useful for the development of effective crop disease management systems. Molecular techniques have accelerated the formulation of short- and long-term strategies of disease management. Exclusion and eradication of plant pathogens by rapid and precise detection and identification of microbial pathogens in symptomatic and asymptomatic plants and planting materials by employing molecular methods has been practiced extensively by quarantines and certification programs with a decisive advantage. Identification of sources of resistance genes, cloning and characterization of desired resistance genes and incorporation of resistance gene(s) into cultivars and transformation of plants with selected gene(s) have been successfully performed by applying appropriate molecular techniques. Induction of resistance in susceptible cultivars by using biotic and abiotic inducers of resistance is a practical proposition for several crops whose resistance levels could not be improved by breeding or transformation procedures. The risks of emergence of pathogen strains less sensitive or resistant to chemicals have been reduced appreciably by rapid identification of resistant strains and monitoring the occurrence of such strains in different geographical locations.
