ISME J
. 2024 Feb;
18(1).
PMID: 38365913
The soil bacterium Sinorhizobium meliloti can establish a nitrogen-fixing symbiosis with the model legume Medicago truncatula. The rhizobia induce the formation of a specialized root organ called nodule, where they...

Plant Cell Environ
. 2022 Jul;
45(10):3100-3121.
PMID: 35781677
Senescence determines plant organ lifespan depending on aging and environmental cues. During the endosymbiotic interaction with rhizobia, legume plants develop a specific organ, the root nodule, which houses nitrogen (N)-fixing...

Syska C, Brouquisse R, Alloing G, Pauly N, Frendo P, Bosseno M, et al.
Front Plant Sci
. 2019 Dec;
10:1496.
PMID: 31850013
The interaction between legumes and bacteria of rhizobia type results in a beneficial symbiotic relationship characterized by the formation of new root organs, called nodules. Within these nodules the bacteria,...

ISME J
. 2017 May;
11(10):2394-2398.
PMID: 28548657
Arbuscular mycorrhizal fungi (AMF) are widespread root symbionts that perform important ecological services, such as improving plant nutrient and water acquisition. Some AMF from the Gigasporaceae family host a population...

Environ Microbiol
. 2014 Aug;
16(12):3714-29.
PMID: 25156344
The symbiotic nitrogen-fixing soil bacterium Sinorhizobium meliloti carries a large number of toxin-antitoxin (TA) modules both on the chromosome and megaplasmids. One of them, the vapBC-5 module that belongs to...

Oswald C, Smits S, Hoing M, Sohn-Bosser L, Dupont L, Le Rudulier D, et al.
J Biol Chem
. 2008 Sep;
283(47):32848-59.
PMID: 18779321
The ATP-binding cassette transporter ChoVWX is one of several choline import systems operating in Sinorhizobium meliloti. Here fluorescence-based ligand binding assays were used to quantitate substrate binding by the periplasmic...

J Bacteriol
. 2006 Aug;
188(17):6308-17.
PMID: 16923898
Sinorhizobium meliloti uses proline betaine (PB) as an osmoprotectant when osmotically stressed and as an energy source in low-osmolarity environments. To fulfill this dual function, two separate PB transporters, BetS...

Dupont L, Garcia I, Poggi M, Alloing G, Mandon K, Le Rudulier D
J Bacteriol
. 2004 Sep;
186(18):5988-96.
PMID: 15342567
In Sinorhizobium meliloti, choline is the direct precursor of phosphatidylcholine, a major lipid membrane component in the Rhizobiaceae family, and glycine betaine, an important osmoprotectant. Moreover, choline is an efficient...

. 2002 Apr;
184(10):2654-63.
PMID: 11976294
Hybridization to a PCR product derived from conserved betaine choline carnitine transporter (BCCT) sequences led to the identification of a 3.4-kb Sinorhizobium meliloti DNA segment encoding a protein (BetS) that...
