Galactosides in the rhizosphere: Utilization by Sinorhizobium meliloti and development of a biosensor
Identifying the types and distributions of organic substrates that support microbial activities around plant roots is essential for a full understanding of plant–microbe interactions and rhizosphereExpand

HPrK regulates succinate-mediated catabolite repression in the gram-negative symbiont Sinorhizobium meliloti.
The HPrK kinase/phosphatase is a common component of the phosphotransferase system (PTS) of gram-positive bacteria and regulates catabolite repression through phosphorylation/dephosphorylation of itsExpand

Sinorhizobium meliloti mutants lacking phosphotransferase system enzyme HPr or EIIA are altered in diverse processes, including carbon metabolism, cobalt requirements, and succinoglycan production.
Sinorhizobium meliloti is a member of the Alphaproteobacteria that fixes nitrogen when it is in a symbiotic relationship. Genes for an incomplete phosphotransferase system (PTS) have been found inExpand

Use of green fluorescent protein to visualize the early events of symbiosis between Rhizobium meliloti and alfalfa (Medicago sativa).
A gene encoding a variant of green fluorescent protein (GFP) of Aequorea victoria was put under the control of a promoter which is constitutive in Rhizobium meliloti. The heterologous GFP gene wasExpand

Adaptation of Escherichia coli to the uncoupler of oxidative phosphorylation 2,4-dinitrophenol.
Escherichia coli was found to adapt to the uncoupler of oxidative phosphorylation 2,4-dinitrophenol. The rates of synthesis of 53 proteins were increased following exposure to 2,4-dinitrophenol.Expand

Resource Exchange in the Rhizosphere: Molecular Tools and the Microbial Perspective
The interface between living plant roots and soils (the rhizosphere) is a central commodities exchange, where organic carbon flux from roots fuels decomposers that, in turn, can make nutrientsExpand

Synergistic effects of soil microstructure and bacterial EPS on drying rate in emulated soil micromodels
Microbial extracellular polymeric substances (EPS) have been shown to alter soil moisture retention and to improve seedling survival and plant growth at the bulk scale. The mechanisms of EPS-mediatedExpand
