Centaurea Sect. Cyanus: Nuclear Phylogeny, Biogeography, and Life-Form Evolution
The authors' results confirm the eastern origin of Cyanus of Centaurea, which probably arose from a Caucasian and North Iranian stock, and monophyletic, and annuals (subsect. Cyanus) arose from perennials in Anatolia. Expand
Assessing the genetic diversity of Centaurea parlatoris group (sect. Dissectae, Compositae) in Sicily using isozymes
This study involves eight Sicilian populations of the C. parlatoris group and the obtained dendrogram reflects the recent taxonomic treatment of the group, and can provide means for both assessment of the future impact of erosion on diversity and elaboration of effective conservation strategies for these endemic taxa.
