A highly conserved repetitive sequence from Physarum polycephalum contains nucleotide arrangements similar to replicator sequences.
An interspersed repetitive sequence from Physarum polycephalum has been cloned and analysed. The 394 bp sequence is highly conserved and contains several homopolymeric (dA)-(dT) tracts capable of forming bent DNA structures and a 10/11 match to the yeast-ARS-consensus sequence. The repetition frequency of the described sequence is about 3000 to 7000, a number that would fit with the distribution of replicator segments in Physarum.
