A Determination Of Phylogeny And Hybridization History Within Clematis L. (Ranunculaceae) Using Actin And Nitrate Reductase Intron Sequences, Kimberly Fearn Do

Graduate Theses and Dissertations

The phylogeny of Clematis, section Viorna, was characterized in this study using molecular data. Two nuclear introns were sequenced for a variety of taxa: actin and nitrate reductase. Actin intron sequence data yielded very little phylogenetic information. Some basal clades were resolved, but there were very few well supported relationships between species of the Viorna section in both the neighbor joining and maximum parsimony analyses. Nitrate reductase intron sequence data was slightly more variable. The number of well supported relationships in both the neighbor joining and maximum parsimony analyses for nitrate reductase was greater, but still not sufficient to yield ...
