The Biology of Frankia and Actinorhizal Plants by Christa R. Schwintzer Pdf

The Biology of Frankia and Actinorhizal Plants provides a comprehensive review of Frankia and the actinorhizal plants. It reviews the state of knowledge on all aspects from molecular genetics through ecology to practical applications; describes methods used in research and practical applications; and is a guide to the literature. The book begins with overviews of Frankia and the actinorhizal plants, and developments in the field prior to the first confirmed isolation of Frankia. Next is a series of authoritative chapters on the biology of Frankia, the symbiosis, and actinorhizal plants. Although methods used in research and in practical applications are included throughout the book, they are given special emphasis in the middle section. The final section of the book concerns the ecology and current and potential uses of actinorhizal plants in both the temperate regions and the tropics. This work is intended as a reference text and handbook of methods for a wide audience including established workers and students of Frankia and actinorhizal plants, specialists and students in other areas of nitrogen fixation (including the Rhizobium-legume symbiosis), soil microbiologists, plant physiologists, ecologists, general biologists, foresters, specialists in land reclamation, and managers requiring an authoritative overview of this rapidly developing field.

Frankia and Actinorhizal Plants by M. Lalonde,C. Camiré,J.O. Dawson Pdf

The fifth meeting of scientists working with Frankia and actinorhizal plants was held at Montmorency Forest of Laval University in Quebec from August 6-8, 1984. Results of research presented at the meeting are included in this special volume of Plant and Soil. The understanding of actinorhizal systems continue to increase, though work and use shops and discussions at this and similar meetings make it evident that this important subject remains open for fruitful investigation at all levels. Some important 'firsts' were reported at this meeting. The first extensive survey of Frankiae and their host specificity ranges from Asia was presented. This is of significance since Asia is a center of diversity for many actinorhizal host plant genera. A report that proto plasts of Frankia have been produced and regenerated for the first time improves the possibility for genetic manipulation of Frankia. It is also important to note the first report herein of successful mass inoculation of actinorhizal plants commercially for stabilization and reclamation of disturbed soils around hydroelectric power projects in Quebec. This heralds the transfer of actinorhizal technology to private and public users. The bacterial genus Frankia is easily recognized both in vivo and in vitro, and isolation of this organism has become routine. But, as yet, there are not sufficient biochemical, morphological, or anatomical criteria for establishing species.

Frankia Symbioses by A.D. Akkermans,D. Baker,K. Huss-Danell,J.D. Tjepkema Pdf

Five years have now passed since the first symposium on frankiae was held at Harvard Forest, Petersham, Massachusetts, USA and the inauguration of the term actinorhiza. Many advances have been made during these five years in our understanding of the actinorhizal symbioses. Evidence for this was provided by the papers presented at the Wageningen Workshop on Frankia symbioses, held in Wageningen at the Department of Microbiology of the Agricultural University. Most of these papers are now published in this volume of PLANT AND SOIL. We kindly acknowledge the assistance of Anton Houwers, editor of the journal, in planning, reviewing and publishing these studies. Although the papers presented at Wageningen described the active research areas, they also illuminated those aspects of these symbioses which remain beyond our understanding. Primary among the areas of our ignorance is the concept of species within the bacterial symbiont, Frankia. At present groupings of bacterial strains are based on cell chemistry, physiology, serology, DNA homology and symbiotic capa bilities (cross-inoculation). When these classification schemes are merged no clear species framework is obtained. Undoubtedly part of the difficulty is due to a lack of strains for analysis. Currently bacterial strains from only half of the actinorhizal symbioses known to exist, have been isolated and studied in pure culture. We must postpone there fore any comprehensive taxonomic classification until a larger majority of the symbioses are represented. Another research area wherein our understanding is insufficient is host-symbiont interaction.

Microbiome-Host Interactions by D. Dhanasekaran,Dhiraj Paul,N. Amaresan,A. Sankaranarayanan,Yogesh S. Shouche Pdf

Microbiota are a promising and fascinating subject in biology because they integrate the microbial communities in humans, animals, plants, and the environment. In humans, microbiota are associated with the gut, skin, and genital, oral, and respiratory organs. The plant microbial community is referred to as "holobiont," and it is influential in the maintenance and health of plants, which themselves play a role in animal health and the environment. The contents of Microbiome-Host Interactions cover all areas as well as new research trends in the fields of plant, animal, human, and environmental microbiome interactions. The book covers microbiota in polar soil environments, in health and disease, in Caenorhabditis elegans, and in agroecosystems, as well as in rice root and actinorhizal root nodules, speleothems, and marine shallow-water hydrothermal vents. Moreover, this book provides comprehensive accounts of advanced next-generation DNA sequencing, metagenomic techniques, high-throughput 16S rRNA sequencing, and understanding nucleic acid sequence data from fungal, algal, viral, bacterial, cyanobacterial, actinobacterial, and archaeal communities using QIIME software (Quantitative Insights into Microbial Ecology). FEATURES Summarizes recent insight in microbiota and host interactions in distinct habitats, including Antarctic, hydrothermal vents, speleothems, oral, skin, gut, feces, reproductive tract, soil, root, root nodules, forests, and mangroves Illustrates the high-throughput amplicon sequencing, computational techniques involved in the microbiota analysis, downstream analysis and visualization, and multivariate analysis commonly used for microbiome analysis Describes probiotics and prebiotics in the composition of the gut microbiota, skin microbiome impact in dermatologic disease prevention, and microbial communities in the reproductive tract of humans and animals Presents information in a reachable way for students, teachers, researchers, microbiologists, computational biologists, and other professionals who are interested in strengthening or enlarging their knowledge about microbiome analysis with next-generation DNA sequencing in the different branches of the sciences

Rhizotrophs: Plant Growth Promotion to Bioremediation by Samina Mehnaz Pdf

This book describes the contributions of rhizotrophs – microbes associated with the parts of plants below ground – in sustainable agriculture. It covers a broad range of aspects, from plant growth promotion to bioremediation. It highlights the role of bacteria, actinomycetes, mycorrhizal fungi, and most interestingly protists, in the sustainability of agriculture. Further, it addresses in detail the involvement of quorum sensing signals, and the role of hydrolytic enzymes and bacteriocin in combating the phytopathogen. The book sheds light on the interaction of rhizotrophs in rhizosphere and how these microbes support plants growing under adverse stress conditions such as saline, drought or heavy-metals contamination. Challenges faced in the field application of these microbes, strategies for modifying the rhizosphere to improve crop yield, and the latest advances in rhizobial bioformulations are also discussed. Overall, the book provides comprehensive information on how various microbes can be used to improve the sustainability of agriculture without disturbing the environment.

Biological Nitrogen Fixation by Frans J. de Bruijn Pdf

Nitrogen is arguably the most important nutrient required by plants. However, the availability of nitrogen is limited in many soils and although the earth's atmosphere consists of 78.1% nitrogen gas (N2) plants are unable to use this form of nitrogen. To compensate , modern agriculture has been highly reliant on industrial nitrogen fertilizers to achieve maximum crop productivity. However, a great deal of fossil fuel is required for the production and delivery of nitrogen fertilizer. Moreover carbon dioxide (CO2) which is released during fossil fuel combustion contributes to the greenhouse effect and run off of nitrate leads to eutrophication of the waterways. Biological nitrogen fixation is an alternative to nitrogen fertilizer. It is carried out by prokaryotes using an enzyme complex called nitrogenase and results in atmospheric N2 being reduced into a form of nitrogen diazotrophic organisms and plants are able to use (ammonia). It is this process and its major players which will be discussed in this book. Biological Nitrogen Fixation is a comprehensive two volume work bringing together both review and original research articles on key topics in nitrogen fixation. Chapters across both volumes emphasize molecular techniques and advanced biochemical analysis approaches applicable to various aspects of biological nitrogen fixation. Volume 1 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 2 covers the symbiotic interaction of nitrogen fixing organisms with their host plants, including nodulation and symbiotic nitrogen fixation, plant and microbial "omics", cyanobacteria, diazotrophs and non-legumes, field studies and inoculum preparation, as well as nitrogen fixation and cereals. Covering the full breadth of current nitrogen fixation research and expanding it towards future advances in the field, 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.
