Abstract

IS1389, a new insertion sequence belonging to the IS3 family, has been identified in Xanthomonas campestris pv. amaranthicola. The genome of this bacterium contains at least 11 copies of the element, whereas no hybridizing sequences were detected in other Xanthomonas species [X. axonopodis, X. fragaridae, X. phaseoli, and X. (Stenotrophomonas) maltophila]. Two nearly identical copies of the element (IS1389-A and IS1389-B) were characterized. According to analysis of sequence alignments and similar structural features, IS1389 belongs to the IS407 subgroup of the IS3 family, which duplicates 4bp of target DNA upon insertion. IS1389-A was found in the proximity of the modification gene of the XamI restriction-modification system.
