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
Gilles Lortet,Nathalie Mear,Jean Lorquin,Bernard Dreyfus,P. de Lajudie,Charles Rosenberg,C. Boivin +6 more
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
Nod factors from Sinorhizobium saheli and S. teranga bv. sesbaniae are both arabinosylated and fucosylated, a structural feature specific to Sesbania rostrata symbionts

TL;DR: Sesbania spp.
Journal ArticleDOI
In Rhizobium meliloti, the operon associated with the nod box n5 comprises nodL, noeA and noeB, three host‐range genes specifically required for the nodulation of particular Medicago species

TL;DR: It is shown that the presence of nodL, and hence of O‐acetylated Nod factors, is a major prerequisite for confering the ability to nodulate alfalfa upon the heterologous bacterium Rhizobium tropici.
Journal ArticleDOI
Sinorhizobium teranga bv. acaciae ORS1073 and Rhizobium sp. strain ORS1001, two distantly related Acacia-nodulating strains, produce similar Nod factors that are O carbamoylated, N methylated, and mainly sulfated.
TL;DR: Compounds from both strains were found to be similar, i.e., mainly sulfated, O carbamoylated, and N methylated, indicating a close relationship between host specificity and Nod factor structure, regardless of the taxonomy of the bacterial symbiont.
Journal ArticleDOI
The Sesbania Root Symbionts Sinorhizobium saheli and S. teranga bv. sesbaniae Can Form Stem Nodules on Sesbania rostrata, although They Are Less Adapted to Stem Nodulation than Azorhizobium caulinodans.
TL;DR: This last property, together with its host-specific symbiotic nitrogen fixation, makes Azorhizobium highly specialized for stem nodulation of the aquatic legume Sesbania rostrata.
