Viability of Rhizobium bacteroids [PDF]
Applied and Environmental Microbiology, 1977 Bacteroids prepared from nodules of soybean and bean were tested for viability. Contrary to the prevailing view that bacteroids are nonviable, it was found that bacteroids averaged 90% viability, irrespective of Rhizobium strain, nodule age, or nodule environment.

Microbiological Reviews, 1995 Rhizobium, Bradyrhizobium, and Azorhizobium species are able to elicit the formation of unique structures, called nodules, on the roots or stems of the leguminous host. In these nodules, the rhizobia convert atmospheric N2 into ammonia for the plant. To establish this symbiosis, signals are produced early in the interaction between plant and rhizobia ...

The Type VI secretion system of Rhizobium etli Mim1 has a positive effect in symbiosis.
FEMS Microbiology Ecology, 2019 The Type VI secretion systems (T6SSs) allow bacteria to translocate effector proteins to other bacteria or to eukaryotic cells. However, little is known about the role of T6SS in endosymbiotic bacteria. In this work we describe the T6SS of Rhizobium etli

Multidisciplinary approaches for studying rhizobium-legume symbioses.
Canadian Journal of Microbiology (print), 2018 The rhizobium-legume symbiosis is a major source of fixed nitrogen (ammonia) in the biosphere. The potential for this process to increase agricultural yield while reducing the reliance on nitrogen-based fertilizers has generated interest in understanding

Expression of Rhizobium meliloti nod genes in Rhizobium and Agrobacterium backgrounds [PDF]
Journal of Bacteriology, 1987 Rhizobium meliloti nod genes are required for the infection of alfalfa. Induction of the nodC gene depends on a chemical signal from alfalfa and on nodD gene expression. By using a nodC-lacZ fusion, we have shown that the induction of the R. meliloti nodC gene and the expression of nodD occur at almost normal levels in other Rhizobium backgrounds and ...

The Role of Plant Innate Immunity in the Legume-Rhizobium Symbiosis.
Annual Review of Plant Biology, 2017 A classic view of the evolution of mutualism is that it derives from a pathogenic relationship that attenuated over time to a situation in which both partners can benefit. If this is the case for rhizobia, then one might uncover features of the symbiosis

Scientific Reports, 2018 Four plant tumorigenic strains 932, 1019, 1078T and 1081 isolated from cane gall tumors on thornless blackberry (Rubus sp.) were characterized. They shared low sequence identity with related Rhizobium spp. based on comparisons of 16S rRNA gene (≤98%) and

plasmids and Host-range in Rhizobium leguminosarum and Rhizobium phaseoli [PDF]
Microbiology, 1980 Summary: Rhizobium phaseoli strain 1233 forms nitrogen-fixing nodules on Phaseolus vulgaris and produces a brown pigment (probably melanin) in plate culture. This strain contains two plasmids of molecular weight about 200 × 106. Spontaneous deletions in the smaller plasmid abolished pigment production and the ability to nodulate Phaseolus beans ...
