Characterization of nitric oxide-inducing lipid A derived from Mesorhizobium loti lipopolysaccharide.

Mesorhizobium loti is a member of the rhizobia and forms nitrogen-fixing symbioses with several Lotus species. Recently, it was reported that M. loti bacterial cells and their lipopolysaccharide (LPS) preparations transiently induced nitric oxide (NO) production in the roots of L.
