Abstract
Restriction fragment length polymorphism (RFLP) in the reverse transcriptase domain of family 1 retrotransposons was investigated in the genera Triticum and Aegilops. On the basis of the TaqI restriction site distribution within or near the reverse transcriptase domain, we defined the four types (I-IV) of the family 1 wheat retrotransposons. The type I elements are assumed to have been present much before the differentiation of the genera because they distribute in rye and barley. On the other hand, the type II-IV elements appeared to have occurred during speciation of Triticum and Aegilops species and were transmitted vertically from species of lower ploidy to those of higher ploidy, because they distribute in most of the polyploid species whereas they are detectable only in six of 15 diploid species. These findings suggest a possibility that the genomes carrying the new family 1 retrotransposons have been preferred in successful establishment of polyploid species.<br>
