Nuclear DNA contents, rDNAs, and karyotype evolution in Vicia subgenus Vicia: II. Section Peregrinae.
Nuclear DNA contents, automated karyotype analyses, and sequences of rDNA spacers have been determined for the species of Vicia belonging to sect. Peregrinae, as well as for V. mollis. The phylogenetic data generated from the comparison of rDNA sequences and karyomorphological results would both indicate that Vicia mollis is a sister group to sect. Peregrinae. The relationships among the species belonging to the Peregrinae section and species enclosed in sections Faba, Narbonensis, and Bithynicae have been also investigated: a clade including V. mollis and sect. Peregrinae is a sister group to a clade including V. bithynica and sect. Narbonensis. With our choice of outgroup, Vicia faba (including subsp. paucijuga) is external to the above mentioned inclusive group.
