TL;DR: The extracellular Nod factors of Rhizobium fredii USDA257, a nitrogen-fixing symbiont of soybean, and several other legume species are isolated and characterized and elicit root-hair deformations on soybean and two other plants.

The NodA proteins of Rhizobium meliloti and Rhizobium tropici specify the N‐acylation of Nod factors by different fatty acids
Frédéric Debellé,Claire Plazanet,Philippe Roche,Céline Pujol,Arlette Savagnac,Charles Rosenberg,Jean-Claude Promé,Jean Dénarié +7 more
TL;DR: Results show that NodA proteins of R. meliloti and R. tropici specify the N‐acylation of Nod factors by different fatty acids, and that allelic variation of the common nodA gene can contribute to the determination of host range.

Structure of the Mesorhizobium huakuii and Rhizobium galegae Nod factors: a cluster of phylogenetically related legumes are nodulated by rhizobia producing Nod factors with alpha,beta-unsaturated N-acyl substitutions

TL;DR: The results suggest that legumes nodulated by rhizobia synthesizing αU‐NFs constitute a phylogenetic cluster in the Galegoid phylum.

Séparation et étude structurale des espéces moléculaires de monomycolates et de dimycolates de α-d-tréhalose présents chez Mycobacterium phlei
TL;DR: Mixtures of dimycolates of α-d-trehalose (cord factor) and monomycolates have been isolated from Mycobacterium phlei and separated as trimethylsilyl derivatives according to the polarity of the fatty acid residues.

Rhizobium fredii synthesizes an array of lipooligosaccharides, including a novel compound with glucose inserted into the backbone of the molecule
Marie Pierre Bec-Ferté,Hari B. Krishnan,Arlette Savagnac,Steven G. Pueppke,Jean-Claude Promé +4 more
TL;DR: It is shown that a mutant strain can replace vaccenic acid with a C16:0 side chain, and that strain USDA191 synthesizes additional LCOs that differ from one another in the length and unsaturation of their fatty acyl substituents.
