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.

Book Synopsis Symbiotic Nitrogen Fixation by : P. Graham
Download or read book Symbiotic Nitrogen Fixation written by P. Graham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.

Book Synopsis Domestication, Fertilization, and Nodulation by : Gwendolyn Fry
Download or read book Domestication, Fertilization, and Nodulation written by Gwendolyn Fry and published by . This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phaseolus vulgaris L. (Latin American common bean) is a leguminous crop that is significant in the life histories of both human civilization and nitrogen-fixing bacteria called rhizobia. These associations are evident from the impacts they have left on the genome of the common bean. As a legume, the common bean has several genes that code for the initiation and maintenance of mutualistic endosymbiosis with rhizobia. Over the course of its domestication and cultivation, the common bean has also undergone simultaneous artificial selection and multiple bottlenecks. As it exists in commercial agriculture, crops of common bean lack within-population genetic diversity and are widely considered poor at facilitating nitrogen fixation. Recent studies suggest nitrogen fertilization to be key in the decline of nodulation in cultivars of common bean. In addition, preliminary research suggests that wild lineages of bean have greater numbers of nodules. However, these data do not directly compare proxies of nitrogen fixation, like nodulation, with genotype and the presence of nitrogen fertilizer. I hypothesized that bean accession would be a more significant factor than nitrogen presence in determining the ability to facilitate nitrogen fixation. Through a randomized block greenhouse experiment that observed the variables of accession and nitrogen treatment, I found that both nitrogen fertilization and genotype were significant contributors to root:shoot ratio, nodule number, and chlorophyll content index (CCI) in common bean. However, bean genotype was more significant in determining ability to facilitate nitrogen fixation.

Book Synopsis Competitive Nodulation of Bean (Phaseolus Vulgaris L.) Rhizobium Spp. with a Broad Host Range by : Katrien Vlassak
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 ...
Book Synopsis Manganese Toxicity in the Rhizobium-bean Symbiosis (Phaseolus Vulgaris L.) by : Johanna Döbereiner
Download or read book Manganese Toxicity in the Rhizobium-bean Symbiosis (Phaseolus Vulgaris L.) written by Johanna Döbereiner and published by . This book was released on 1963 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect on manganese toxicity on the nitrogen fixing symbiosis in Phaseolus vulgaris was studied. In 4 laboratory experiments the resistence to manganese of 20 strains of Rhizobium phaseoli, growing in liquid culture medium with different H-ion concentrations, was studied. Three greenhouse experiments werw carried out to observe manganese toxicity effects on plant growth, nodulation and nitrogen fixation, at two H-ion concentrations and at three calcium levels. Rhizobium growth was affected only by manganese concentrations above 100 ppm, when the Ph of the medium was above 6.0. At pH4.6 however, 25 ppm manganese were toxic to most of the strains. Different strains varied in their sensitivity to manganese and to high H-ion concentrations but the two effects were independent of each other. plant passage in normal plants or in plants showing manganese toxicity symptoms and containing more than 1200 ppm manganese, had no effect on the ability of the strains to grow in culture medium containing high manganese concentrations. Manganese concentrations of 12.5 and 25.0 ppm on a sand weight basis reduced the total nitrogen in plants per pot by 13% when ammonium nitrate was the nitrogen source. The total nitrogen in the plant dependent on symbiotic nitrogen fixation was reduced by 30 t0 60% depending on the inoculated strain of Rhizobium phaseoli. Increasing manganese levels reduced the dry weight and nitrogen content of plants, the nodule number and size, the nodule weight and the hemoglobin and nitrogen content in ...
