DOI: 10.1002/jobm.202200552
Abstract: Bacterial surface components and extracellular compounds such as exopolysaccharides (EPSs) are crucial for interactions between cells, tolerance to different types of stress, and host colonization. Sinorhizobium meliloti produces two EPSs: Succinoglycan (EPS I), which is… read more here.

DOI: 10.1007/s13199-018-0547-2
Abstract: Improving symbiotic nitrogen fixation would reduce reliance on synthetic fertilizers, but establishment of effective bacterial strains is hampered due to competition by indigenous, less effective rhizobia. This study investigated the origins, diversity, and competitiveness of… read more here.

DOI: 10.1042/bsr20202956
Abstract: Abstract Sinorhizobium meliloti is a nitrogen-fixing bacterium forming symbiotic nodules with the legume Medicago truncatula. S. meliloti possesses two BolA-like proteins (BolA and YrbA), the function of which is unknown. In organisms where BolA proteins… read more here.

DOI: 10.1071/cp18124
Abstract: Abstract. Acidic conditions with damaging levels of available aluminium (Al3+) currently limit lucerne (Medicago sativa) production on soils in the New Zealand high country and in large areas of Australia. Increased lucerne nodulation could be… read more here.

DOI: 10.1099/mic.0.001293
Abstract: We previously showed that specific polyamines (PAs) present in the extracellular environment markedly affect extracellular polysaccharide (EPS) production, biofilm formation and motility in Sinorhizobium meliloti Rm8530. We hypothesized that extracellular PA signals were sensed and… read more here.

DOI: 10.1111/1758-2229.13079
Abstract: Sinorhizobium meliloti infects the host plant alfalfa to induce formation of nitrogen-fixation root nodules, which inevitably elicit reactive oxygen species (ROS) bursts and organic peroxide generation. The MarR family regulator OhrR regulates the expression of… read more here.

DOI: 10.1128/jb.00614-17
Abstract: ABSTRACT The chemosensory system in Sinorhizobium meliloti has several important deviations from the widely studied enterobacterial paradigm. To better understand the differences between the two systems and how they are optimally tuned, we determined the… read more here.

Dual-Uptake Mode of the Antibiotic Phazolicin Prevents Resistance Acquisition by Gram-Negative Bacteria
Sign Up to like & getrecommendations! Published in 2023 at "mBio"
DOI: 10.1128/mbio.00217-23
Abstract: Many bacteria produce antimicrobial peptides to eliminate competitors and create an exclusive niche. These peptides act either by membrane disruption or by inhibiting essential intracellular processes. ABSTRACT Phazolicin (PHZ) is a peptide antibiotic exhibiting narrow-spectrum… read more here.
