Three kinds of DNA sequences (here called TrsB, TrsC and <i>RIRE1</i>) have been previously reported to be those repeated in tandem specifically in the wild rice species with FF, CC or EE genome, respectively. To characterize these genome type-specific sequences, we carried out PCR using a pair of primers, which hybridize to a restricted region in the repeating unit sequence and prime DNA synthesis in both directions. Gel electrophoresis and DNA sequencing revealed that PCR using primers for TrsB (or TrsC) amplified the fragments with an integral series of a unit length not only from total DNA of the rice strain with FF (or CC) genome, but also from those of the rice strains with non-FF (or non-CC) genome. TrsB or TrsC was, however, found to be repeated in an extraordinary number of copies in the species with FF or CC genome, respectively, in which the TrsB (or TrsC) sequence has been originally identified. PCR using primers for <i>RIRE1</i> produced various sizes of fragments from total DNA of the rice strains with EE genome. The fragments, however, showed no progression at interval of the unit length characteristic for tandem repeats. Nucleotide sequencing of the amplified fragments revealed that they were not the sequences repeated in tandem, but were those interspersed as an element having partial homology with the LTR sequences of retrotransposons, <i>Wis-2-1A</i> in wheat and <i>BARE-1</i> in barley. <i>RIRE1</i> was present in the rice species with any types of genomes, but in the species with EE genome in an extraordinary number of copies.<br>
