title: Characterization of a family of tandemly repetitive DNA sequences from the fern sawfly, Strongylogaster osmundae (Hymenoptera: Tenthredinidae).
abstract: A family of repetitive DNA sequences in the genome of the sawfly, Strongylogaster osmundae (Hymenoptera: Tenthredinidae) was characterized. The family consists of a tandemly arranged array whose basic repeat unit is 1.0 kb. According to the compositions and arrangements of bases, the basic repeat unit can be divided into three distinct domains. Three domains share nucleotide sequence homology of 88, 74 and 89%, respectively, between members in this family. Second domain which had lower homology with the other two domains was found characteristically rich with polypurine/polypyrimidine sequences.
