title: Sinorhizobium teranga bv. acaciae ORS1073 and Rhizobium sp. strain ORS1001, two distantly related Acacia-nodulating strains, produce similar Nod factors that are O carbamoylated, N methylated, and mainly sulfated.
abstract: We have determined the structures of Nod factors produced by strains representative of Sinorhizobium teranga bv. acaciae and the so-called cluster U from the Rhizobium loti branch, two genetically different symbionts of particular Acacia species. Compounds from both strains were found to be similar, i.e., mainly sulfated, O carbamoylated, and N methylated, indicating a close relationship between host specificity and Nod factor structure, regardless of the taxonomy of the bacterial symbiont.
