Origin and evolution of North American polyploid Silene (Caryophyllaceae)
Nuclear DNA sequences from introns of the low‐copy nuclear gene family encoding the second largest subunit of RNA polymerases and the ribosomal internal transcribed spacer (ITS) regions, combined with the psbE‐petL spacer and the rps16 intron from the chloroplast genome were used to infer origins an...
