This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les plantes se développent et évoluent en interaction avec les organismes du sol. L'impact des vers de terre sur la croissance des plantes, généralement positif, a été attribué à des modifications physiques, chimiques ou biochimiques du sol, souvent sans démonstration rigoureuse. Dans ce travail, les techniques développées en sciences du végétal (culture in vitro, utilisation de mutants et transcriptomique) ont été utilisées afin de comprendre les mécanismes à l'origine de l'effet des vers de terre sur les plantes. Nos résultats apportent de nouvelles connaissances fondamentales: (1) la production de molécules-signal à l'intérieur des déjections de vers de terre a un impact significatif sur la croissance d'Oryza sativa et Lolium perenne. (2) Ces molécules agissent sur la voie de signalisation fortement liée à l'auxine, comme suggéré par l'effet significatif du ver de terre sur la croissance du double mutant d'A. thaliana aux1-7;axr4-2. (3) L'abondance de ces molécules-signal en présence de vers de terre pourrait être liée à la stimulation de certaines populations bactériennes capables de synthétiser de l'auxine. (4) Le ver de terre induit une accumulation de transcrits pour des gènes sous contrôle de l'acide jasmonique et de l'éthylène. Ces hormones sont notamment impliquées dans un mécanisme de résistance systémique induite (ISR), connu pour être induit par certaines rhizobactéries promotrices de la croissance des plantes. Enfin, (5) le piétin échaudage, maladie due à un champignon pathogène, déclenche chez le blé (Triticum aestivum) une réaction d'hypersensibilité et une modification de la signalisation hormonale, qui sont considérées comme des mécanismes de contrôle du métabolisme de la plante qui facilitent l'infection du pathogène. La sévérité de cette maladie est réduite en présence de vers de terre. La synthèse de ces résultats indique que les vers de terre, comme d'autres organismes du sol, modifient l'équilibre hormonal de la plante. L'homéostasie hormonale apparaît comme un élément incontournable pour prédire l'issue des interactions multiples que les plantes entretiennent avec les organismes du sol.

Book Synopsis Environmental Adaptations and Stress Tolerance of Plants in the Era of Climate Change by : Parvaiz Ahmad
Download or read book Environmental Adaptations and Stress Tolerance of Plants in the Era of Climate Change written by Parvaiz Ahmad and published by Springer Science & Business Media. This book was released on 2011-12-02 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is a complex phenomenon with a wide range of impacts on the environment. Biotic and abiotic stress are a result of climate change. Abiotic stress is caused by primary and secondary stresses which are an impediment to plant productivity. Prolonged exposure to these stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to withstand these stresses, e.g. synthesis of osmolytes, osmoprotectants, and antioxidants. Stress responsive genes and gene products including expressed proteins are implicated in conferring tolerance to the plant. This volume will provide the reader with a wide spectrum of information, including vital references. It also provides information as to how phytoconstituents, hormones and plant associated microbes help the plants to tolerate the stress. This volume also highlights the use of plant resources for ameliorating soil contaminants such as heavy metals. Dr. Parvaiz is Assistant professor in Botany at A.S. College, Srinagar, Jammu and Kashmir, India. He has completed his post-graduation in Botany in 2000 from Jamia Hamdard New Delhi India. After his Ph.D from the Indian Institute of Technology (IIT) Delhi, India in 2007 he joined the International Centre for Genetic Engineering and Biotechnology, New Delhi. He has published more than 20 research papers in peer reviewed journals and 4 book chapters. He has also edited a volume which is in press with Studium Press Pvt. India Ltd., New Delhi, India. Dr. Parvaiz is actively engaged in studying the molecular and physio-biochemical responses of different plants (mulberry, pea, Indian mustard) under environmental stress. Prof. M.N.V. Prasad is a Professor in the Department of Plant Sciences at the University of Hyderabad, India. He received B.Sc. (1973) and M.Sc. (1975) degrees from Andhra University, India, and the Ph.D. degree (1979) in botany from the University of Lucknow, India. Prasad had published 216 articles in peer reviewed journals and 82 book chapters and conference proceedings in the broad area of environmental botany and heavy metal stress in plants.

Book Synopsis Recent advances in crop protection by : P.Parvatha Reddy
Download or read book Recent advances in crop protection written by P.Parvatha Reddy and published by Springer Science & Business Media. This book was released on 2012-09-14 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the recent years, the need to increase food production to meet the demands of rapidly increasing population from a limited land resource necessitated the use of intensive farming systems, with the inputs like narrow genetic base, high dose of fertilizers, pesticides, irrigation, monocropping, etc. which led to the development of diseases and pest. The effect of changing global climate, particularly the sharp increase in CO2 concentration, has increased the susceptibility of plants to pathogens and pests. Because of the chemicalization of agriculture, the age-old eco-friendly pest management practices like sanitation, crop rotation, mixed cropping, adjustment of date of planting, fallowing, summer ploughing, green manuring, composting, etc. are not being practiced, affecting the crops adversely. This has encouraged researchers to look for eco-friendly and novel approaches for pest management. The information on recent advances in crop protection (involving bacteria, fungi, nematodes, insects, mites and weeds) is scattered. The book delves upon the most latest developments in crop protection such as avermectins, bacteriophages, biofumigation, biotechnological approaches; bio-priming of seeds; disguising the leaf surface; use of non-pathogenic strains, plant defense activators, plant growth promoting rhizobacteria, pathogenesis-related proteins, strobilurin fungicides, RNA interference, and variety of mixtures/cultivar mixtures/multilines; soil solarization; biointensive integrated pest management; among several others (fusion protein-based biopesticides, seed mat technology and environmental methods). This book is a ready reference for students, policy-makers, scientists, researchers and extension workers.

Book Synopsis Bacteria in Agrobiology: Crop Ecosystems by : Dinesh K. Maheshwari
Download or read book Bacteria in Agrobiology: Crop Ecosystems written by Dinesh K. Maheshwari and published by Springer Science & Business Media. This book was released on 2011-04-19 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future of agriculture strongly depends on our ability to enhance productivity without sacrificing long-term production potential. An ecologically and economically sustainable strategy is the application of microorganisms, such as the diverse bacterial species of plant growth promoting bacteria (PGPB). The use of these bio-resources for the enhancement of crop productivity is gaining worldwide importance. Bacteria in Agrobiology: Crop Ecosystems describes the beneficial role of plant growth promoting bacteria with special emphasis on oil yielding crops, cereals, fruits and vegetables. Chapters present studies on various aspects of bacteria-plant interactions, soil-borne and seed-borne diseases associated with food crops such as rice, sesame, peanuts, and horticultural crops. Further reviews describe technologies to produce inoculants, the biocontrol of post harvest pathogens as a suitable alternative to agrochemicals, and the restoration of degraded soils.
Book Synopsis Nutrient Dynamics for Sustainable Crop Production by : Ram Swaroop Meena
Download or read book Nutrient Dynamics for Sustainable Crop Production written by Ram Swaroop Meena and published by Springer Nature. This book was released on 2019-09-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cropping system is one of the important components of sustainable agriculture, since it provides more efficient nutrient cycling. As such, balanced fertilization must be based on the concept of sustainable crop production. Feeding the rapidly growing world population using environmentally sustainable production systems is a major challenge, especially in developing countries. A number of studies have highlighted the fact that degradation of the world's cultivated soils is largely responsible for low and plateauing yields. Soil is lost rapidly but only formed over millennia, and this represents the greatest global threat to nutrient dynamics in agriculture. This means that nutrient management is essential to provide food and nutritional security for current and future generations. Nutrient dynamics and soil sustainability imply the maintenance of the desired ecological balance, the enhancement and preservation of soil functions, and the protection of biodiversity above and below ground. Understanding the role of nutrient management as a tool for soil sustainability and nutritional security requires a holistic approach to a wide range of soil parameters (biological, physical, and chemical) to assess the soil functions and nutrient dynamics of a crop management system within the desired timescale. Further, best nutrient management approaches are important to advance soil sustainability and food and nutritional security without compromising the soil quality and productive potential. Sustainable management practices must allow environmentally and economically sustainable yields and restore soil health and sustainability. This book presents soil management approaches that can provide a wide range of benefits, including improved fertility, with a focus on the importance of nutrient dynamics. Discussing the broad impacts of nutrients cycling on the sustainability of soil and the cropping systems that it supports, it also addresses nutrient application to allow environmentally and economically sustainable agroecosystems that restore soil health. Arguing that balanced fertilization must be based on the concept of INM for a cropping system rather than a crop, it provides a roadmap to nutrient management for sustainability. This richly illustrated book features tables, figures and photographs and includes extensive up-to-date references, making it a valuable resource for policymakers and researchers, as well as undergraduate and graduate students of Soil Science, Agronomy, Ecology and Environmental Sciences.
