BacS: An Abundant Bacteroid Protein in \u3cem\u3eRhizobium etli\u3c/em\u3e Whose Expression Ex Planta Requires \u3cem\u3enifA\u3c/em\u3e [PDF]
, 2003 Rhizobium etli CFN42 bacteroids from bean nodules possessed an abundant 16-kDa protein (BacS) that was found in the membrane pellet after cell disruption. This protein was not detected in bacteria cultured in tryptone-yeast extract.

The Irr and RirA proteins participate in a complex regulatory circuit and act in concert to modulate bacterioferritin expression in Ensifer meliloti 1021 [PDF]
, 2017 In this work we found that the bfr gene of the rhizobial species Ensifer meliloti, encoding a bacterioferritin iron storage protein, is involved in iron homeostasis and the oxidative stress response. This gene is located downstream of and overlapping the

Identification of genomic regions associated with partial resistance to Aphanomyces root rot in pea
The Plant Genome, Volume 18, Issue 4, December 2025.Abstract Root rot caused by Aphanomyces euteiches is a major concern in pea (Pisum sativum L.). The lack of other effective control strategies makes crucial the development of resistant varieties. Although partial resistance has been reported, its quantitative inheritance, the association of resistance‐linked genomic regions with unfavorable agronomic ...

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.14CO2 and 32PO4 labelling of bean was used with Rhizobium tropici mutants. An alkaline phosphatase mutant was not affected for bacteroid P acquisition, though bacteroid and nodule 14C‐carbon uptake was altered. The high‐affinity P transporter mutant was defective in nodule P acquisition and symbiotic performance. Plant image by Brgfx/Freepik.

Bacterial fitness for plant colonization is influenced by plant growth substrate
New Phytologist, Volume 248, Issue 6, Page 3168-3190, December 2025.Summary Despite advances in our understanding of bacterial plant colonization, the extent to which growth substrate influences the molecular mechanisms enabling bacteria to efficiently colonize plants remains poorly understood. To address this, we used randomly barcoded transposon mutagenesis sequencing (RB‐TnSeq) in Paraburkholderia graminis OAS925 ...

Sinorhizobium fredii HH103 RirA is required for oxidative stress resistance and efficient symbiosis with Soybean [PDF]
, 2019 Members of Rhizobiaceae contain a homologue of the iron-responsive regulatory protein RirA. In different bacteria, RirA acts as a repressor of iron uptake systems under iron-replete conditions and contributes to ameliorate cell damage during oxidative ...

Input of nitrogen from N2 fixation to northern grasslands [PDF]
, 2005 Forage legumes form N2-fixing symbioses with rhizobia and may thus make substantial contributions to the N pool in grasslands. However, to optimize their use as sources of N, it is important to elucidate the effects of management factors that influence ...
