dc.description.abstractTandemly repeated DNAs, referred to as satellite DNAs, often occur in a genome in a genus-specific manner. However, the mechanisms for generation and evolution for these sequences are largely unknown because of the uncertain origins of the satellite DNAs. We found highly divergent genus-specific satellite DNAs that showed sequence similarity with genus-specific intergenic spacers (IGSs) in the family Solanaceae, which includes the genera Nicotiana, Solanum and Capsicum. The conserved position of the IGS between 25S and 18S rDNA facilitates comparison of IGS sequences across genera, even in the presence of very low sequence similarity. Sequence comparison of IGS may elucidate the procedure of the genesis of complex monomer units of the satellite DNAs. Within the IGS of Capsicum species, base substitutions and copy number variation of subrepeat monomers were causes of monomer divergence in IGS sequences. At the level of inter-generic IGS sequences of the family Solanaceae, however, genus-specific motif selection, motif shuffling between subrepeats and differential amplification among motifs were involved in formation of genus-specific IGS. Therefore, the genus-specific satellite DNAs in Solanaceae plants can be generated from differentially organized repeat monomers of the IGS rather than by accumulation of mutations from pre-existent satellite DNAs.-
