Download or read book Competitive Nodulation of Bean Phaseolus Vulgaris L Rhizobium Spp with a Broad Host Range written by Katrien Vlassak and published by . This book was released on 1996 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inoculation of legumes with superior nitrogen fixing rhizobia does not always result in the desired increase because of the failure of the inoculation strain to occupy a significant proportion of the nodules. The introduced inoculant strains have to compete with the indiginous, often ineffective nitrogen fixing, rhizobial population at different levels: after their adaptation and multiplication in the soil and host rhizosphere, these strains have to compete on the legume roots for infection sites and nodulation. Although the success of inoculation depends for a great extent on the ratio of inoculant to indigenous rhizobia, the intrinsic characteristics of these rhizobia, and their responses to many abiotic and biotic environmental factors also determine the outcome of inoculation. Common bean (Phaseolus vulgaris L.) is an important crop in Latin America, supplying about 20% of the protein intake per person (Van Rheenen, 1982). The factors which influence the interaction between this legume and its microsymbiont are insufficiently known, and often no response is observed after inoculation of this crop. Recently, Rhizobium spp, such as R.tropici IIB, which nodilate a wide variety of tropical legumes, were indentified. These strains maintain their good symbiotic properties, even at the adverse environmental conditions frequently encountered in tropical soils (Martinez-Romero et al., 1991; Hungria et al., 1993), and consequently, appear promising as commercial inoculant for beans. In this work, the competitive ...
Download or read book Handbook for Rhizobia written by Padma Somasegaran and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rhizobia are bacteria which inhabit the roots of plants in the pea family and "fix" atmospheric nitrogen for plant growth. They are thus of enormous economic importance internationally and the subject of intense research interest. Handbook for Rhizobia is a monumental book of practical methods for working with these bacteria and their plant hosts. Topics include the general microbiological properties of rhizobia and their identification, their potential as symbionts, methods for inoculating rhizobia onto plants, and molecular genetics methods for Rhizobium in the laboratory. The book will be invaluable to Rhizobium scientists, soil microbiologists, field and laboratory researchers at agricultural research centers, agronomists, and crop scientists.

Download or read book Microbial Resource Conservation written by Sushil K. Sharma and published by Springer. This book was released on 2018-10-31 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers broad areas in the conservation of microorganisms. It addresses the short, medium and long-term preservation of agriculturally important microorganisms, as well as culture collections and their roles. The respective chapters address topics such as conventional approaches to bacterial, fungal and algal preservation, as well as methods and strategies for preserving recalcitrant microorganisms. Readers will also find the latest insights into the preservation of vesicular-arbuscular (VA) fungi and ecology, diversity and conservation of endophytes, and entamopathogenic fungi. Microbes of animal and dairy origin, their preservation and biosafety issues are also explored. Microorganisms are the silent and unseen majority of life on Earth, and are characterized by a high degree of genetic and metabolic diversity. It is well documented that no branch of science or society is unaffected by microbial interventions. Researchers have documented microorganisms from such extreme and unique environments as deserts and hydrothermal vents, and with specific traits that are currently being exploited in agriculture, industry, medicine and biotechnological applications. Such great potential can only be found in microorganisms. The aim of this book – the first entirely devoted to the conservation of microorganisms, and to regulatory mechanisms for access and benefits sharing as per Biological Diversity (BD) Act 2002 – is to promote awareness of our world’s microbial wealth, and to introduce readers to strategies and methodologies for the conservation of microorganisms, which could ultimately save human life on Earth.

Download or read book Molecular Microbial Ecology of the Soil written by Gudni G. Hardarson and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain legume crops, e.g. common bean (Phaseolus vulgaris L.), and soyabeans (Glycine max L.) are amongst the main sources of protein in Africa, Asia and Latin America. Their high protein content derive from their ability, in symbiosis with Rhizobium bacteria, to fix atmospheric nitrogen. Incorporating contributions from molecular biologists, microbiologists, plant breeders and soil scientists, this volume reports the results of an FAO/IAEA Co-ordinated Research Programme (1992-1996), whose main objective was to develop molecular biological methods to study rhizobial ecology. Use of better tracking methods will help enhance biological nitrogen fixation and thus grain legume yields, while reducing their reliance on soil- and/or fertilizer-nitrogen. This volume will be invaluable to scientists working on biological nitrogen fixation, soil microbial ecology and legume production.
Download or read book Sociology Organic Farming Climate Change and Soil Science written by Eric Lichtfouse and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book series gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.
Download or read book Advances in Biology and Ecology of Nitrogen Fixation written by Takuji Ohyama and published by BoD – Books on Demand. This book was released on 2014-01-29 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation has essential role in N cycle in global ecosystem. Several types of nitrogen fixing bacteria are recognized: the free-living bacteria in soil or water; symbiotic bacteria making root nodules in legumes or non-legumes; associative nitrogen fixing bacteria that resides outside the plant roots and provides fixed nitrogen to the plants; endophytic nitrogen fixing bacteria living in the roots, stems and leaves of plants. In this book there are 11 chapters related to biological nitrogen fixation, regulation of legume-rhizobium symbiosis, and agriculture and ecology of biological nitrogen fixation, including new models for autoregulation of nodulation in legumes, endophytic nitrogen fixation in sugarcane or forest trees, etc. Hopefully, this book will contribute to biological, ecological, and agricultural sciences.
