Riou N, Le Rudulier D
J Gen Microbiol
. 2012 Sep;
136(8):1455-61.
PMID: 22991739
Addition of glycine betaine (1 mM) stimulated aerobic growth of Azospirillum brasilense Sp 7 in the presence of 0.3 M-NaC1. The nitrogenase activity of whole cells was particularly sensitive to...

. 2001 Jul;
183(16):4709-17.
PMID: 11466273
By transposon mutagenesis, we have isolated a mutant of Sinorhizobium meliloti which is totally unable to grow on fructose as sole carbon source as a consequence of its inability to...

Boncompagni E, Dupont L, Mignot T, Osteras M, Lambert A, Poggi M, et al.
J Bacteriol
. 2000 Jun;
182(13):3717-25.
PMID: 10850986
The symbiotic soil bacterium Sinorhizobium meliloti uses the compatible solutes glycine betaine and proline betaine for both protection against osmotic stress and, at low osmolarities, as an energy source. A...

Osteras M, Boncompagni E, Vincent N, Poggi M, Le Rudulier D
Proc Natl Acad Sci U S A
. 1998 Sep;
95(19):11394-9.
PMID: 9736747
Glycine betaine is a potent osmoprotectant accumulated by Sinorhizobium meliloti to cope with osmotic stress. The biosynthesis of glycine betaine from choline is encoded by an operon of four genes,...

Brhada F, Poggi M, Le Rudulier D
Curr Microbiol
. 1997 Mar;
34(3):167-72.
PMID: 9009070
Two strains of Rhizobia isolated from nodules of Vicia faba var. major and one strain isolated from nodules of Cicer arietinum L. were characterized for salt resistance. The presence of...

J Bacteriol
. 1994 Nov;
176(22):6877-84.
PMID: 7961447
The mechanism of osmoadaptation in a salt-tolerant (1.2 M NaCl) bacterial isolate identified as Pseudomonas mendocina (N. J. Palleroni, M. Doudoroff, R. Y. Stanier, R. E. Solanes, and R. Mandel,...

Riou N, Poggi M, Le Rudulier D
Biochimie
. 1991 Sep;
73(9):1187-93.
PMID: 1747385
Azospirillum brasilense is able to use glycine betaine as a powerful osmoprotectant; the uptake of this compound is strongly stimulated by salt stress, but significantly reduced by cold osmotic shock....

Plant Physiol
. 1991 Aug;
96(4):1228-36.
PMID: 16668324
Ethanol-soluble organic acid, carbohydrate, and amino acid constituents of alfalfa (Medicago sativa) roots and nodules (cytosol and bacteroids) have been identified by gas-liquid chromatography and high performance liquid chromatography. Among...

Biochim Biophys Acta
. 1991 Jan;
1061(2):197-205.
PMID: 1847827
The effect of salt stress on glycine betaine-binding activity has been investigated in periplasmic fractions released from Rhizobium meliloti 102F34 by cold osmotic shock. Binding activity was monitored by three...

Gauthier M, Flatau G, Le Rudulier D, Clement R, Combarro Combarro M
Appl Environ Microbiol
. 1991 Jan;
57(1):272-6.
PMID: 1674654
The high resistance of Escherichia coli grown in saline media to seawater was suppressed by an osmotic down-shock. The shock released several molecules into the medium, including potassium, glutamate, and...
