A Proteomic Network for Symbiotic Nitrogen Fixation Efficiency in Bradyrhizobium elkanii [PDF]

Molecular Plant-Microbe Interactions®, 2018
Rhizobia colonize legumes and reduce N2 to NH3 in root nodules. The current model is that symbiotic rhizobia bacteroids avoid assimilating this NH3. Instead, host legume cells form glutamine from NH3, and the nitrogen is returned to the bacteroid as dicarboxylates, peptides, and amino acids.

Especificidade hospedeira de variantes Bradyrhizobium spp em soja (cvs peking e clark), caupi e guandu Host specificity of Bradyrhizobium spp mutants in soybean (cultivars peking and clark), cowpea and pigeon pea

Revista Brasileira de Ciência do Solo, 2008
A expansão da cultura da soja evidenciou uma alta especificidade hospedeira, requerendo a pesquisa de novas estirpes que apresentassem capacidade de nodular a soja e bom potencial de competição com a população de rizóbios naturalizada nos solos.

Seeds inoculation and nitrogen fertilization for cowpea production on latosol in the western amazon

Bioscience Journal, 2017
The cowpea is an important food crop in the North and Northeast regions of Brazil, where the beans are consumed either green or ripe. Yet, considering its socio-economic importance and its tropical origin, cowpea yields are low in those regions, due to ...

Ein universeller, kontinuierlicher Assay für SAM‐abhängige Methyltransferasen

Angewandte Chemie, Volume 135, Issue 51, December 18, 2023., 2023
Die Identifizierung neuer oder verbesserter Methyltransferasen (MTs) kann eine Schlüsselrolle bei der Entwicklung neuer pharmazeutischer Wirkstoffe (APIs) spielen, da sie die chemo‐ und regioselektive Methylierung von O‐, N‐, S‐ und C‐Atomen katalysieren. Um geeignete SAM‐abhängige MTs zu identifizieren, wurde der erste universelle, fluoreszenzbasierte

A Universal, Continuous Assay for SAM‐dependent Methyltransferases

Angewandte Chemie International Edition, Volume 62, Issue 51, December 18, 2023., 2023
Identification of novel or improved methyltransferases (MTs) may play a key role in the development of new active pharmaceutical ingredients (APIs), as they catalyze the chemo‐ and regioselective methylation of O‐, N‐, S‐ and C‐atoms. To identify suitable SAM‐dependent MTs, the first universal, fluorescence‐based high‐throughput MT assay compatible ...

A Selective Medium for the Isolation and Quantification of Bradyrhizobium japonicum and Bradyrhizobium elkanii Strains from Soils and Inoculants [PDF]

Applied and Environmental Microbiology, 1994
The ecological examination of members of the family Rhizobiaceae has been hampered by the lack of a selective medium for isolation of root nodule bacteria from soil. A novel non-antibiotic-containing medium has been developed which allows selective isolation of Bradyrhizobium japonicum and

High Temperatures and Bacillus Inoculation Affect the Diversity of Bradyrhizobia in Cowpea Root Nodules. [PDF]

J Basic Microbiol
ABSTRACT Future climatic scenario predictions indicate a substantial temperature increase, reducing crop production worldwide and demanding the development of adaptations in agriculture. This study aimed to assess the impact of high temperatures and amendments with Bacillus on nodulating bradyrhizobia.

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 ...
