Handbook for Rhizobia

Handbook for Rhizobia PDF Author: Padma Somasegaran
Publisher: Springer Science & Business Media
ISBN: 1461383757
Category : Technology & Engineering
Languages : en
Pages : 456

Book Description
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.

Stable Isotope Techniques in the Study of Biological Processes and Functioning of Ecosystems

Stable Isotope Techniques in the Study of Biological Processes and Functioning of Ecosystems PDF Author: M.J. Unkovich
Publisher: Springer Science & Business Media
ISBN: 9780792370789
Category : Nature
Languages : en
Pages : 312

Book Description
This book has a very strong practical orientation, telling readers what methodologies are available using stable isotopes, how studies should be designed and executed to maximise effectiveness and incisiveness in terms of data obtained and outcomes in terms of understanding events and processes in plant and ecosystem functioning. The readership is very much aimed toward postgraduates with good knowledge of general biological principles and underlying chemical and physical processes. Pre-existing knowledge of or experience in application and assay of stable isotopes is not required. The stable isotope research field is one of the most rapidly growing areas of ecophysiology and techniques using stable isotopes comprise an ever increasing component of research programs of university postgraduates and a wide range of agencies conducting environmental monitoring and rehabilitation programs. The book is tailor-made for such an audience.

Biological Nitrogen Fixation, Biological Nitrogen Fixation

Biological Nitrogen Fixation, Biological Nitrogen Fixation PDF Author: Frans J. de Bruijn
Publisher: John Wiley & Sons
ISBN: 9781118637074
Category : Science
Languages : en
Pages : 0

Book Description
Biological Nitrogen Fixation is a comprehensive 3 volume work bringing together both review and original research articles on key topics in nitrogen fixation. Chapters across all three volumes emphasize molecular techniques and advanced biochemical analysis approaches applicable to various aspects of biological nitrogen fixation, but each volume also has a unique focus: Volume I explores the chemistry and biochemistry of nitrogenases, nif gene regulation, the taxonomy, evolution, and genomics of nitrogen fixing organisms, as well as their physiology and metabolism. Volume II covers the symbiotic interaction of nitrogen fixing organisms with their host plants, including nodulation and symbiotic nitrogen fixation. Volume III features chapters on the "omics" of nitrogen fixing organisms and host plants, nitrogen fixing cyanobacteria and archaea, nitrogen fixing plant growth promoting rhizobacteria and non-legumes, as well as field studies and nitrogen fixation in cereals. Covering the full breadth of current nitrogen fixation research and synthesizing it to point the way forward,Biological Nitrogen Fixation will be a one-stop reference for microbial ecologists and environmental microbiologists as well as plant and agricultural researchers working on crop sustainability.

Advances in Biology and Ecology of Nitrogen Fixation

Advances in Biology and Ecology of Nitrogen Fixation PDF Author: Takuji Ohyama
Publisher: BoD – Books on Demand
ISBN: 9535112163
Category : Science
Languages : en
Pages : 286

Book Description
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.
