In this study the description of a new insertion sequence of Sinorhizobium meliloti , IS Rm10 , is reported. IS Rm10 was found in the intergenic region between nodJ and nodQ of a natural isolated strain. IS Rm10 was 1047 bp long and showed the typical features of the ISs belonging to the IS630‐Tc1/IS3 superfamily. In particular the IS Rm10 nucleotide sequence showed the highest homology (62%) with a Sphingomonas aromaticivorans IS. IS Rm10 was present in 32% of the analyzed S. meliloti strains while it was not found in the reference strains of other Rhizobium species.
