- ... Various lipo-chitin molecules were tested for their ability to induce the expression of the early nodulin, ENOD2, in Glycine soja roots. When inoculated separately onto G. soja roots, LCO-V (C18:1 delta 11,Mefuc), LCO-V (C18:1 delta 9,Mefuc), LCO-V (C16:0,Mefuc), and LCO-IV (C16:0) were unable to induce ENOD2 expression, even though these compounds had previously been shown to induce root hair cur ...

- ... Rhizobia synthesize a class of lipo-chitin oligosaccharides that induce root hair deformation and induce the initiation of nodule structures on legume roots. These lipo-chitin oligosaccharides are tetra- and penta-lipo-oligosaccharides of N-acetylglucosamine with an acyl substitution on the nonreducing end and are commonly known as Nod factors. In this study, we demonstrate that synthetic analogs ...
