ISRm10: a new insertion sequence of Sinorhizobium meliloti: nucleotide sequence and geographic distribution.
In this study the description of a new insertion sequence of Sinorhizobium meliloti, ISRm10, is reported. ISRm10 was found in the intergenic region between nodJ and nodQ of a natural isolated strain. ISRm10 was 1047 bp long and showed the typical features of the ISs belonging to the IS630-Tc1/IS3 superfamily. In particular the ISRm10 nucleotide sequence showed the highest homology (62%) with a Sphingomonas aromaticivorans IS. ISRm10 was present in 32% of the analyzed S. meliloti strains while it was not found in the reference strains of other Rhizobium species.
