Genetic and Environmental Modulation of the Chickpea - Mesorhizobium Symbiosis
… pathogens. As chickpea is nodulated with diverse Mesorhizobium species, genetic factors related to both rhizobia and host plant, and environmental conditions are likely to influence plant growth and defence, and chickpea-Mesorhizobium symbiosis. The primary objective of this thesis is to …

Estudio de glutarredoxinas y de un factor de transcripci?n de respuesta a etileno diferencialmente expresados en la simbiosis Lotus japonicus - Mesorhizobium loti
… Lotus japonicus cuando crecía en simbiosis con Mesorhizobium loti. Concretamente, esos genes codificaban una serie de glutarredoxinas (GRXs) pertenecientes a la clase III, un grupo de GRXs que aparece exclusivamente en plantas superiores, y un factor de transcripción de respuesta a etileno …

Systematics, Specificity, and Ecology of New Zealand Rhizobia
… legumes were predominately nodulated by diverse Mesorhizobium spp. that contain three different nodA genotypes (two of which are novel) that have transferred between rhizobial strains. The Mesorhizobium spp. showed little nodulation specificity and could nodulate an exotic legume Astragalus (milk …

Edaphic factors and rhizobia influence the distribution of legumes (Fabaceae) in the Core Cape Subregion of South Africa
… the two main rhizobial genera (Burkholderia and Mesorhizobium) that nodulate various legumes of the CCR, and to determine the diversity and phylogenetic position of rhizobia that associate with the narrowly distributed and rare Indigofera superba in the CCR. The first objective was pursued …

METHYLATED AMINE-UTILISING BACTERIA AND MICROBIAL NITROGEN CYCLING IN MOVILE CAVE
… isolates from the genera Catellibacterium and Mesorhizobium. Pathways for monomethylamine (MMA) metabolism were investigated using new PCR primers designed to target gmaS, the gene for gammaglutamylmethylamide synthetase, a key enzyme of the recently characterised indirect MMA oxidation …

Discovery of function in the enolase superfamily
… subgroup members from Agrobacterium tumefaciens, Mesorhizobium loti, Polaromonas sp., Silicibacter sp. and Sinorhizobium meliloti. The glucarate degradation operon in Escherichia coli encodes two enolase superfamily members: D-glucarate dehydratase (GlucD) and its catalytically impaired close …

Exploring the Potential of Algae-Bacteria Communities For Biotechnology
… association of interest is between the bacterium Mesorhizobium loti (Rhizobiales) and the green alga, Lobomonas rostrata deficient in the production of vitamin B12. The alga provides fixed carbon to the bacterium whereas the bacterium supplies vitamin B12 to the alga. In the course of a screen for …

Investigation of the role of root flavonoids in the interaction of chickpea with nitrogen-fixing symbionts and parasitic nematodes
… 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, attraction …

Experimental and Theoretical Study of Carbon Dynamics in an Algal-Bacterial Co-Culture
… and a B12-producing, heterotrophic bacterium, Mesorhizobium loti. The interaction between these two species is a type of mutualism, because both species benefit from the presence of the other. The bacteria provide B12 to the algae and in exchange the bacteria are able to metabolise some of the …

A METE mutant of Chlamydomonas reinhardtii provides new perspectives on the evolution of vitamin B12 auxotrophy
… one-carbon metabolism. The rhizobial bacterium Mesorhizobium loti formed a commensal relationship with wild-type C. reinhardtii, benefiting from the alga’s photosynthate. When co-cultured with metE7 this interaction should be considered a mutualism as the alga was dependent on bacterial B12. …

A computational biology approach to studying algae-bacterial interactions
… Lobomonas rostrata and the alpha-proteobacterium Mesorhizobium loti. In the model system, it is known that the bacterium provides vitamin B12 to the alga and itself, whilst the alga provides fixed carbon. I have applied methods from the field of computational biology to study the interactions …

Vitamin B12-mediated physiology, mutualisms, and gene regulation studies in Chlamydomonas reinhardtii and Phaeodactylum tricornutum
… to form a mutualism with B12-producing bacteria Mesorhizobium loti and Rhodospirillum rubrum. An RNA sequencing experiment was conducted with samples taken just after initiation of a co-culture and then after subculturing once. Clean reads ranging from 53-81 million were obtained with ~95% …
