Multilocus sequence analysis (MLSA) of Bradyrhizobium strains: revealing high diversity of tropical diazotrophic symbiotic bacteria. [PDF]

, 2017
Symbiotic association of several genera of bacteria collectively called as rhizobia and plants belonging to the family Leguminosae (=Fabaceae) results in the process of biological nitrogen fixation, playing a key role in global N cycling, and also ...

Indolepyruvate Pathway for Indole-3-Acetic Acid Biosynthesis in Bradyrhizobium elkanii [PDF]

Plant and Cell Physiology, 1996
Indole-3-acetaldehyde (IAAId) was detected in the culture supernatant of Bradyrhizobium elkanii. Deuteriumlabelled L-tryptophan (Trp) was incorporated into IAAId and indole-3-acetic acid (IAA), suggesting that B. elkanii produces IAA via IAAId from Trp. In B.

DNA Sequence and Mutational Analysis of Rhizobitoxine Biosynthesis Genes in Bradyrhizobium elkanii [PDF]

Applied and Environmental Microbiology, 2001
ABSTRACT We cloned and sequenced a cluster of genes involved in the biosynthesis of rhizobitoxine, a nodulation enhancer produced by Bradyrhizobium elkanii . The nucleotide sequence of the cloned 28.4-kb DNA region encompassing rtxA showed that several open reading frames (ORFs ...

Rhizobitoxine production inAgrobacterium tumefaciensC58 byBradyrhizobium elkanii rtxACDEFGgenes [PDF]

FEMS Microbiology Letters, 2007
We examined the genetic basis and transfer for production of rhizobitoxine, an inhibitor of ethylene biosynthesis in plants, directed by the rtx genes of Bradyrhizobium elkanii. Comparison with genome sequences of Bradyrhizobium japonicum and Xanthomonas oryzae suggests that the rtx genes extend from the previously identified rtxAC genes through four ...

Classificação taxonômica das estirpes de rizóbio recomendadas para as culturas da soja e do feijoeiro baseada no seqüenciamento do gene 16S rRNA Taxonomic classification of rhizobial strains recommended for soybean and common bean crops in Brazil based on the sequencing of the 16s rRNA gene

Revista Brasileira de Ciência do Solo, 2003
As culturas da soja [Glycine max (L.) Merrill] e do feijoeiro (Phaseolus vulgaris L.) são de grande importância econômica e social para o Brasil e ambas podem ter seu requerimento de nitrogênio suprido pela simbiose com bactérias da ordem Rhizobiales ...

Compatibility of adzuki bean (Vigna angularis) and Bradyrhizobium USDA strains, and geographical distribution and community structure on indigenous adzuki bean-nodulating bradyrhizobia in Japan

Plant Protection Science, 2023
We investigated the compatibility between adzuki bean and Bradyrhizobium USDA strains and the relation between the genetic diversity of indigenous adzuki bean-nodulating bradyrhizobia and their geographical distribution in Japan.

Quantitative and time-course evaluation of nodulation competitiveness of rhizobitoxine-producing Bradyrhizobium elkanii [PDF]

FEMS Microbiology Ecology, 2003
Abstract Regression analysis of results from a mathematical competition model showed that rhizobitoxine production by Bradyrhizobium elkanii USDA94 gave this strain a nodulation competitiveness about 10 times greater than that of a non-rhizobitoxine-producing mutant strain on Macroptilium atropurpureum (Siratro).

Influence of flooding and soil properties on the genetic diversity and distribution of indigenous soybean-nodulating bradyrhizobia in the Philippines

Heliyon, 2018
One of the strategies that is commonly used in the Philippines to improve the production of soybean is by inoculation. However, this technique often fails mainly due to the lack of information about the indigenous soybean rhizobia in the Philippines soil.

Widespread Distribution of Highly Adapted Bradyrhizobium Species Nodulating Diverse Legumes in Africa

Frontiers in Microbiology, 2019
Bradyrhizobium is one of the most cosmopolitan and diverse bacterial group nodulating a variety of host legumes in Africa, however, the diversity and distribution of bradyrhizobial symbionts nodulating indigenous African legumes are not well understood ...

Rhizobitoxine Production by Bradyrhizobium elkanii Enhances Nodulation and Competitiveness on Macroptilium atropurpureum [PDF]

Applied and Environmental Microbiology, 2000
ABSTRACT Application of 1-aminoocyclopropane-1-carboxylic acid, an ethylene precursor, decreased nodulation of Macroptilium atropurpureum by Bradyrhizobium elkanii. B. elkanii produces rhizobitoxine, an ethylene synthesis inhibitor. Elimination of rhizobitoxine production in
