Rhizobium meliloti Genes Encoding Catabolism of Trigonelline Are Induced under Symbiotic Conditions
TL;DR: Results showed that trc genes are induced during all the symbiotic steps, i.e., in the rhizosphere, infection threads, and bacteroids of alfalfa, suggesting that trigonelline is a nutrient source throughout the Rhizobium-legume association.
Journal ArticleDOI
Betaine use by rhizosphere bacteria: genes essential for trigonelline, stachydrine, and carnitine catabolism in Rhizobium meliloti are located on pSym in the symbiotic region.
TL;DR: It is shown that the symbiotic megaplasmid of R. meliloti RCR2011 encodes functions essential to the catabolism of three betaines, trigonelline (nicotinic acid N-methylbetaine), stachydrine (proline betaine or dimethylproline), and carnitine (gamma-trimethyl-beta-hydroxybutyrobetaine).
Journal ArticleDOI
Stem nodulation in legumes: diversity, mechanisms, and unusual characteristics
TL;DR: Rhizobia can establish a nitrogen-fixing symbiosis with plants of the Leguminosae family and elicit on their host plant the formation of new organs, called nodules, which develop on the host plant.
Journal ArticleDOI
Nod factor thin-layer chromatography profiling as a tool to characterize symbiotic specificity of rhizobial strains: application to Sinorhizobium saheli, S. teranga, and Rhizobium sp. strains isolated from Acacia and Sesbania

TL;DR: Thin-layer chromatography (TLC) analysis of the Nod factors synthesized by overproducing strains showed that strains isolated from the same plant genus exhibited similar TLC profiles and profiles of Acacia and Sesbunia symbionts were easily distinguishable, Acacia strains producing, in particular, sulfated molecules.
Journal ArticleDOI
Genetic analysis of a region of the Rhizobium meliloti pSym plasmid specifying catabolism of trigonelline, a secondary metabolite present in legumes.
TL;DR: Screening of a set of R. meliloti strains from various geographical origins showed that all of these strains are able to catabolize trigonelline and show sequence homology between their megaplasmids and a trc probe.
