In rhizobium strains, the lipid A is modified by the addition of a very long-chain fatty acid (VLCFA) shown to play an important role in rigidification of the outer membrane, thereby facilitating their dual life cycle, outside and inside the plant. I

Abstract Legumes have the ability to establish a nitrogen-fixing symbiosis with soil rhizobia that they house in specific organs, the nodules. In most rhizobium-legume interactions, nodulation occurs on the root. However, certain tropical legumes gro

Rhizobial lipo-chitooligosaccharides (LCOs) are signaling molecules involved in host-range recognition for the establishment of the symbiosis with leguminous plants. The major LCO of Rhizobium meliloti , the symbiont of Medicago plants contains four

Revealing the mechanisms of perception of Nod factors is the next great challenge in a quest to understand the determination of partner specificity and subsequent nodule organogenesis in the legume-rhizobia symbiosis. Our biochemical approach to this

Background The NodH sulfotransferase from Sinorhizobium meliloti has been used to radiolabel lipochitooligosaccharidic (LCO) Nod factor signals with 35S from inorganic sulfate in a two-step enzymatic procedure. The first step involved the production
