Background and aimsBurkholderia tuberum STM678T was isolated from a South African legume, but did not renodulate this plant. Until a reliable host is found, studies on this and other interesting beta-rhizobia cannot advance. We investigated B. tuberum STM678T’s ability to induce Fix+ nodules on a small-seeded, easy-to-propagate legume (Macroptilium atropurpureum). Previous studies demonstrated that B. tuberum elicited either Fix- or Fix+ nodules on siratro, but the reasons for this difference… 

Mining the phytomicrobiome to understand how bacterial coinoculations enhance plant growth

TLDR
Genes important for the production of volatiles, polyamines, and antimicrobial peptides as well as genes for such plant growth-promoting traits as phosphate solubilization and siderophore production are detected.

Competition Experiments for Legume Infection Identify Burkholderia phymatum as a Highly Competitive β-Rhizobium

TLDR
Members of the genus Burkholderia (β-proteobacteria) have only recently been shown to be able to establish a nitrogen-fixing symbiosis with several legumes, which is why they are also referred to as β-rhizobia and has the potential to be a very competitive legume symbiont.

Transcriptome Analysis of Paraburkholderia phymatum under Nitrogen Starvation and during Symbiosis with Phaseolus Vulgaris

TLDR
An RNA-sequencing analysis of free-living P. phymatum growing under nitrogen-replete and -limited conditions and from symbiotic root nodules of Phaseolus vulgaris indicated that RpoN and NifA are key regulators during symbiosis with P. vulgaris.

Bacteria-Inducing Legume Nodules Involved in the Improvement of Plant Growth, Health and Nutrition

TLDR
The available data about the ability of the legume nodule-inducing bacteria for improving the plant growth, health and nutrition of both legumes and nonlegumes were revised and showed that rhizobia meet all the requirements of sustainable agriculture to be used as bio-inoculants allowing the total or partial replacement of chemicals used for fertilization or protection of crops.

Bacillus simplex—A Little Known PGPB with Anti-Fungal Activity—Alters Pea Legume Root Architecture and Nodule Morphology When Coinoculated with Rhizobium leguminosarum bv. viciae

TLDR
Combining nodulating, nitrogen-fixing rhizobia with growth-promoting bacteria enhances plant development and strongly supports a coinoculation strategy to improve nitrogen fixation, increase biomass, and establish greater resistance to fungal disease.

Rhizobial Diversity and Nodulation Characteristics of the Extremely Promiscuous Legume Sophora flavescens.

TLDR
An extensive survey on the diversity and biogeography of rhizobia associated with Sophora flavescens, a sophocarpidine (matrine)-containing medicinal legume, and the cross nodulation, infection pattern, light and electron microscopies of root nodule sections show that the bacteroids are regular or irregular rod shape and nonswollen types, indicating the synthesis of PHB in bacteroids isrhizobia-dependent.

Rhizotrophs: Plant Growth Promotion to Bioremediation

  • S. Mehnaz
  • Biology
    Microorganisms for Sustainability
  • 2017
TLDR
Evaluated the strain DS1, a nitrogenfixing, indole acetic acid-producing strain with phosphate solubilization ability, which has promoted the plant growth in most cases and recommended its use as a biofertilizer.

Bukholderia strains promote Mimosa spp. growth but not Macroptilium atropurpureum

TLDR
The aim of this study was to evaluate the relationship and symbiotic efficiency of 14 strains of Burkholderia isolated from rupestrian grasslands, using M. atropurpureum and Mimosa tenuiflora as trap plants, and to establish symbiosis with M. bimucronata and M. foliolosa.

A survey of the microbial community in the rhizosphere of two dominant shrubs of the Negev Desert highlands, Zygophyllum dumosum (Zygophyllaceae) and Atriplex halimus (Amaranthaceae), using cultivation-dependent and cultivation-independent methods.

TLDR
A snapshot of the microbial communities in the Negev Desert, giving an insight in its natural state, identified a number of PGPB, both epiphytes and endophytes, which fix nitrogen, chelate iron, solubilize phosphate, and secrete cellulase, thereby providing a profile of the microbiomes that support the growth of two desert perennials.

Nodulation of Cyclopia spp. (Leguminosae, Papilionoideae) by Burkholderia tuberum.

TLDR
This work investigates whether Burkholderia tuberum strains STM678 and DUS833 can nodulate species of the South African endemic papilionoid genera Cyclopia (tribe Podalyrieae) and Aspalathus (Crotalarieae) as well as the promiscuous legume Macroptilium atropurpureum (Phaseoleae).

Burkholderia phymatum is a highly effective nitrogen-fixing symbiont of Mimosa spp. and fixes nitrogen ex planta.

TLDR
Burkholderia phymatum is therefore an effective Mimosa symbiont with a broad host range, and is the first reported beta-rhizobial strain to fix nitrogen in free-living culture.

Nodulation and nitrogen fixation by Mimosa spp. in the Cerrado and Caatinga biomes of Brazil.

TLDR
It is concluded that nodulation in Mimosa is a generic character, and that the preferred symbionts of Brazilian species are Burkholderia, in the first study to demonstrate N(2) fixation by beta-rhizobial symbioses in the field.

The Tomato Rhizosphere, an Environment Rich in Nitrogen-Fixing Burkholderia Species with Capabilities of Interest for Agriculture and Bioremediation

TLDR
The results revealed a high level of diversity of diazotrophic Burkholderia species, including B. unamae and B. kururiensis, and two other unknown species, which exhibited activities involved in bioremediation, plant growth promotion, or biological control in vitro.

Nitrogen-fixing bacteria communities occurring in soils under different uses in the Western Amazon Region as indicated by nodulation of siratro (Macroptilium atropurpureum)

TLDR
The fact that the highest diversity and nodulation were seen in managed systems such as agriculture and agroforestry suggests a high resilience of LNB communities to changes in land use after deforestation in a region where large forest areas are still preserved and can be a source of propagules.

Legume-nodulating betaproteobacteria: diversity, host range, and future prospects.

TLDR
Initial analyses of genome sequences have suggested that plant-associated Burkholderia spp.

Legume Symbiotic Nitrogen Fixation byβ-Proteobacteria Is Widespread inNature

TLDR
Findings suggest that beta-rhizobia evolved from diazotrophs through multiple lateral nod gene transfers, strongly supporting the hypothesis of the unique origin of common nod genes.
