Distribution of intron rps12i346 in monilophytes. All available lycophyte and monilophyte plastid rps12 genes were aligned, and excerpts of the alignment covering the rps12i346 intron sequences and adjacent rps12 exons are shown. Numbers display the total size of the intron if present in the respective taxon.
