Auxotrophy in rhizobia revisited [PDF]

open access: yesIndian Journal of Microbiology, 2007
Among the various types of mutations studied in rhizobia, the auxotrophic mutations (which confer on the mutants the inability to synthesize certain essential substances such as amino acids, vitamins and nucleic acids), are the most favoured ones as these can be used as suitable markers for genetic analysis.

Symbiotic and genetic diversity of Rhizobium galegae isolates collected from the Galega orientalis gene center in the Caucasus [PDF]

open access: yes, 2003
This paper explores the relationship between the genetic diversity of rhizobia and the morphological diversity of their plant hosts. Rhizobium galegae strains were isolated from nodules of wild Galega orientalis and Galega officinalis in the Caucasus ...

Explaining coexistence of nitrogen fixing and non-fixing rhizobia in legume-rhizobia mutualism using mathematical modeling [PDF]

open access: yes, 2017
In the mutualism established between legumes and soil bacteria known as rhizobia, bacteria from soil infect plants roots and reproduce inside root nodules where they fix atmospheric N2 for plant nutrition, receiving carbohydrates in exchange.

Sinorhizobium fredii Strains HH103 and NGR234 Form Nitrogen Fixing Nodules With Diverse Wild Soybeans (Glycine soja) From Central China but Are Ineffective on Northern China Accessions [PDF]

open access: yes, 2018
Sinorhizobium fredii indigenous populations are prevalent in provinces of Central China whereas Bradyrhizobium species (Bradyrhizobium japonicum, B. diazoefficiens, B. elkanii, and others) are more abundant in northern and southern provinces.

H2S Crosstalk in Rhizobia Modulates Essential Nutrient Allocation and Transport in Soybean

open access: yesAgronomy, 2023
Hydrogen sulfide (H2S), a novel gas signaling molecule, plays a crucial role in plant growth and stress response. However, little attention has been devoted to the regulation of H2S on nutrient transport and utilization in legume–rhizobia symbiosis ...

GuaB Activity Is Required in Rhizobium tropici During the Early Stages of Nodulation of Determinate Nodules but Is Dispensable for the Sinorhizobium meliloti–Alfalfa Symbiotic Interaction [PDF]

open access: yes, 2005
The guaB mutant strain Rhizobium tropici CIAT8999-10T is defective in symbiosis with common bean, forming nodules that lack rhizobial content. In order to investigate the timing of the guaB requirement during the nodule formation on the host common ...

Promoter prediction in the rhizobia [PDF]

open access: yesMicrobiology, 2006
The ability to recognize and predict non-σ54promoters in the alphaproteobacteria is not well developed. In this study, 25 experimentally verifiedSinorhizobium melilotipromoter sequences were compiled and used to predict the location of other related promoters in theS. melilotigenome.

Rhizobium-Linked Nutritional and Phytochemical Changes Under Multitrophic Functional Contexts in Sustainable Food Systems

open access: yesFrontiers in Sustainable Food Systems, 2021
Rhizobia are bacteria that exhibit both endophytic and free-living lifestyles. Endophytic rhizobial strains are widely known to infect leguminous host plants, while some do infect non-legumes.

Cell surface lipopolysaccharides of different rhizobia [PDF]

open access: yesFEMS Microbiology Letters, 1992
Abstract Polyacrylamide gel electrophoresis profiles of various cell surface lipopolysaccharides (LPS) obtained from fast-growing strains and plasmidless mutant strains of Rhizobium ‘hedysari’, R. leguminosarum and from slow-growing Bradyrhizobium japonicum strains have been compared.

Organic Manure Improves Soybean Response to Rhizobia Inoculant and P-Fertilizer in Northern Ghana

open access: yesFrontiers in Agronomy, 2020
Inherently low concentrations of soil nutrients and erratic rainfall pattern in sub-Sahara Africa limit soybean response to rhizobia inoculant and P-fertilizer.
