Phylogenetic analysis of ITS and group I intron sequences from European and North American samples of cetrarioid lichens.
(1998) In Annales Botanici Fennici 35(4). p.275-286- Abstract
- Phylogenetic analyses were carried out on 23 samples representing 10 cetrarioid taxa from Europe and North America, representing 10 cetrarioid taxa; they were compared in parsimony analyses. The study is focused on ITS sequences of the ribosomal DNA. Intervening sequences, most likely representing group I introns, were found in four taxa. The results from the phylogenetic analysis are congruent with species delimitations derived from morphological characters, regardless of the geographic origin of the material. ITS and group I intron sequences from populations within the same species usually differ at very few base positions. The inclusion of Cetraria aculeata (Schreb.) Fr. in Cetraria Ach. and the exclusion of Melanelia hepatizon (Ach.)... (More)

Culb., Flavocetraria Kärnefelt & A. Thell, and Platismatia W. L. Culb. & C. F. Culb. from Cetraria is supported by the analyses, if the genus Vulpicida J.-E. Mattsson and M. J. Lai is maintained in this grouping. (Less)
