   Sammanfattning : DNA sequences from the rps16 intron and the psbE-petL spacer from the chloroplast genome, the ribosomal nuclear ITS region, and introns from the low copy nuclear genes RPA2, RPB2, RPD2a and RPD2b, are in different combinations used to infer phylogenetic relationships in Sileneae (Caryophyllaceae). Used in concert, the biparentally inherited nuclear regions are useful to distinguish between paralogy due to allopolyploidy and single gene duplications, respectively, because the latter are not expected to give rise to repeated phylogenetic patterns in potentially unlinked sequence regions.
