Families of Vascular Plants - EEB337H

Phylogenetic relationships between angiosperm groups appeared to differ depending on whether morphology or DNA sequence variation in a chloroplast gene, a nuclear gene, three genes, or five genes were used as evidence in these early studies (1989-1999). Look at the individual trees in detail by clicking on the links above, and consult the original publications in order to see how well supported the different branches were. Note that I have left out many of the details of each of these trees, summarizing each one so as to facilitate comparison with the morphology tree. In particular, note that the different studies employed more or less different suites of taxa, depending on how labor-intensive the data collection was. Note also that on the individual trees links have been added to the nine families studied intensively in this course. For an up-to-date synthesis of seed plant phylogeny, however, you should visit the Angiosperm Phylogeny Website.
