Phenotypic characterization of rhizobia isolates and distribution of Burkholderia rhizobia in the Core Cape Subregion
… Podalyrieae and Indigofereae. Selected rhizobia that included Burkholderia and Mesorhizobia, the large genera in the isolated rhizobia, and representing beta- and alpha- Proteobacteria were phenotypically characterized to determine the tolerances of Cape isolates to abiotic conditions. …

Legume-rhizobia interactions in a complex microbiome
… restoration. This is primarily conducted by rhizobia (nitrogen fixing bacteria) in association with legume plants. Most research in improving rhizobial strains involves single strain experiments. However, improved metagenomics methods have demonstrated considerable differences between single …

Evolution of energy storage traits in symbiotic rhizobia
… between legume plants and nitrogen-fixing rhizobia involves an inherent conflict-of-interest over how rhizobia allocate the resources they receive from the host plant. In theory, rhizobia could enhance their future fitness by diverting resources from nitrogen-fixation into storage compounds …

Systematics, Specificity, and Ecology of New Zealand Rhizobia
This research investigated the rhizobia that are associated with New Zealand legume plants. Rhizobia are a diverse group of bacteria that live in symbiosis with legumes in root nodules. Rhizobia fix Nitrogen from the atmosphere and provide this nutrient to the plant. The objectives of this research …

Rhizobia inoculant effects on bambara groundnut growth and yield in Namibia
… food security. Thus, the application of rhizobial inoculants at planting significantly improves yields in many leguminous crops. Moreover, symbiotic inoculants are mainly used in developed countries to improve nitrogen fixation and improve productivity of grain legumes. Sub-Saharan …

Phenotypic diversity of indigenous rhizobia nodulating different morphotypes of Vachellia karroo
… nitrogen through its symbiotic relationship with rhizobia. The nitrogen fixed through this biological way is more beneficial than chemical fertilizers as it does not have any harmful effects on the environment, and it is free. There is limited information on the rhizobia nodulating V. karroo …

A Study of the Genetics of Root Nodulation in Pigeonpea (Cajanus cajan) Using Indigenous Rhizobia
… the symbiotic effectiveness of indigenous rhizobia on pigeonpea.. The specific objectives of the study were to: (i) collect rhizobial strains that are associated with root nodulation in pigeonpea from diverse locations across South Africa (ii) perform molecular characterization of the …

REGULATION OF CALCIUM INFLUX AND REACTIVE OXYGEN SPECIES PRODUCTION DURING INFECTION OF LEGUMES BY RHIZOBIA
… elongation. I assessed the role of ROPs during rhizobial infection in M. truncatula and found a ROP-activating protein, MtGAP1, was upregulated in root hairs during bacterial infection and is involved in normal root hair curling and infection thread development. Two pieces of evidence directly …

Rhizobia diversity and their effect on the distribution of indigenous legumes in the Cape Floristic Region
… these legumes are in symbiotic association with rhizobia that nodulate and fix nitrogen in the nutrient poor soils...It was, therefore, hypothesized that rhizobia isolates from indigenous legumes of the CFR will cluster phylogenically according to soil types and that the distribution of rhizobia …

Edaphic factors and rhizobia influence the distribution of legumes (Fabaceae) in the Core Cape Subregion of South Africa
… characteristics) and the distribution of rhizobia have influenced legume distributions in the CCR landscape. The influence of edaphic factors on the distribution of legume species assemblages in the Cape Peninsula (a microcosm of the CCR) is the subject of the second chapter of the thesis. …

Investigation of the role of root flavonoids in the interaction of chickpea with nitrogen-fixing symbionts and parasitic nematodes
… and parasites, often concurrently, in the field. Rhizobia (Mesorhizobium ciceri)-legume (Cicer arietinum) symbiosis and rhizobia-nematode (Meloidogyne javanica) parasitism are linked as there are commonalities during the early signal interaction between host roots and both microbes. For example, …

Indirect genetic effects of rhizobium symbiosis plasmid on legume-grass dynamics
… on nitrogen (N) availability in the environment. Rhizobial bacteria provide fixed N to their legume hosts, and thus the presence or identity of rhizobia can influence host interactions with other species. In Rhizobium symbionts of clover, the genes that determine symbiosis compatibility and …

Isolation, Purification, and Chemical Characterization of the Dihydroxamate-Type Siderophore, "Schizokinen," Produced by <em>Rhizobium leguminosarum</em> IARI 917.
… the iron-siderophore complex into the cytoplasm. Rhizobia are characterized by their ability to form symbiotic relationships with leguminous plants, where they can fix nitrogen for the host plant and the plant provides the bacteria with nutrients. Under iron-limiting conditions, Rhizobia are known …

Ecological and evolutionary aspects of interactions between microbes coinfecting plants
… vein virus (ClYVV)), and a microbial mutualist, rhizobia bacteria. The presence of rhizobia allowed ClYVV to reach higher within-host concentrations in coinfections. Viral transmission was also affected by interactions between coinfection and plant nitrogen source. Viral infection significantly …

Evolutionary and ecological outcomes of tripartite mutualisms
… along their root called nodules wherein rhizobia reside and fix atmospheric nitrogen to plant-available forms (Harris, Pacovsky, & Paul, 1985a). Legumes also interact with arbuscular mycorrhizal fungi (AMF) to form multiple intraradical structures (including arbuscules and hyphae) which …
