Fern Phylogeny Based on rbcL Nucleotide Sequences

Phylogeny of Agavaceae Based on ndhF, rbcL, and its Sequences

Great advances have been made in our understanding of the phylogeny and classification of Agavaceae in the last 20 years. In older systems Agavaceae were paraphyletic due to overemphasis of ovary position or habit. Discovery of a unique bimodal karyotype in Agave and Yucca eventually led to a reexamination of concepts and relationships in all the lilioid monocots, which continues to the present...

Molecular Phylogeny of the Polystichoid Ferns in Asia Based on rbcL Sequences

Polystichum has often been treated as a sub-cosmopolitan genus of 180-230 species (i.e., Polystichum s.l.), but several segregate genera, such as Cyrtogonellum, Cyrtomidictyum, Cyrtomium, Phanerophlebia, and Sorolepidium, have been recognized in various treatments. Together, these genera constitute the polystichoid ferns. We used a data set of 47 species of the polystichoid ferns and three outg...

Phylogeny of the sundews, Drosera (Droseraceae), based on chloroplast rbcL and nuclear 18S ribosomal DNA Sequences.

The sundew genus Drosera consists of carnivorous plants with active flypaper traps and includes nearly 150 species distributed mainly in Australia, Africa, and South America, with some Northern Hemisphere species. In addition to confused intrageneric classification of Drosera, the intergeneric relationships among the Drosera and two other genera in the Droseraceae with snap traps, Dionaea and A...
