Identification of strains of Rhizobium leguminosarum
… due to their symbiotic relationship with Rhizobium spp. Many of these pastoral areas can be subject to dry conditions and drought. For Rhizobium spp. it is important to understand what effect desiccating stress can have and whether there is natural variation in the ability of individual …

Physiological response of Rhizobium leguminosarum during bacteroid development
legume-rhizobia symbioses, free-living rhizobia colonise root nodules and develop into N2 fixing specialists known as bacteroids. During bacteroid development, rhizobia must adapt to the nodule environment, consisting of reactive oxygen species, low oxygen, antimicrobial secondary metabolites, low …

Molecular signalling in Lupinus albus-Rhizobium lupini symbiosis
The symbiotic interaction between Rhizobium lupini and Lupinus albus results in the formation of root nodules where nitrogen fixation takes place. In these associations, molecular signals such as flavonoids (or non-flavonoid type), nod gene-inducers, and bacterial lipochitooligosaccharides (LCOs) …

Efficacy of the biological control agent Rhizobium vitis ARK-1 against tumorigenic Rhizobium vitis, the causal agent of grapevine crown gall
… transformation by the tumorigenic bacterium Rhizobium vitis. Crown gall results in a gradual decline in yield and vine vigor, then the complete collapse of the vine. R. vitis ARK-1, an antagonistic and non-tumorigenic strain, has been shown to inhibit gall formation when equal cell …

Indirect genetic effects of rhizobium symbiosis plasmid on legume-grass dynamics
… host interactions with other species. In Rhizobium symbionts of clover, the genes that determine symbiosis compatibility and efficiency are located on a plasmid (pSym, or symbiosis plasmid), which can be shared within and across taxa through horizontal gene transfer (HGT). Previous work …

Characterization of novel genes involved in cell envelope function in Rhizobium leguminosarum
… genes involved in cell envelope development in Rhizobium leguminosarum. Previous studies have identified a positive correlation between cell envelope defective mutants and an inability to grow on peptide-rich media, as well as minimal media supplemented with 3 mM glycine. Identifying novel genes …
