Title: Rhizobial Lipo-Oligosaccharide Signals: Their Biosynthesis and Their Role in the Plant
Abstract: All tested strains of the genera Rhizobium,Bradyrhizobium. and Azorhizobium are able to produce lipo-oligosaccharide signals upon activation of the flavonoid-inducible nod genes. R.leguminosarum was chosen as a model system to study the biochemical function of the Nod proteins in the synthesis of the lipooligosaccharides. In R.leguminosarum bv. viciae, the operons nodABC and nodFEL encode for the Nod proteins which are minimally required for synthesis of the wild type lipo-oligosaccharides and have therefore been studied in most detail. The NodE protein determines host-specificity by its involvement in the synthesis of highly unsaturated fatty acid moieties. The role of the lipo-oligosaccharides in the host plant will be emphasized. Results are presented which tempt us to believe that lipo-oligosaccharides, similar to those produced by rhizobia, are naturally occurring in the uninfected plant
