Abstract We have determined the nucleotide sequences around the junction points of oligomeric-deleted ptDNAs possessing a head-to-head or tail-to-tail configuration from long-term cultured cell lines and albino plants. It was shown that DNA rearrangement occurred by direct fusion of deleted ptDNAs in an inverted orientation, which was linked by an asymmetrical sequence of 254–698 bp derived from either of the ptDNAs joined. It is notable that inverted repeats of 7–14 bp flank the asymmetrical sequences at each of the junction points. These features of the DNA sequence around the junction points are commonly observed in oligomeric ptDNA with a large-scale deletion regardless of the cell lines employed. It is suggested that the short inverted repeats are involved in the intermolecular recombination of ptDNA.
