The phylogeny of Asimina and Deeringothamnus .

The molecular phylogenetic classification of the North American genera Asimina and Deeringothamnus (Annonaceae) has never been determined with strong support and/or resolution. In this analysis, ISSR DNA fingerprinting techniques were used in order to elucidate the phylogeny of the group. DNA was extracted from accessions from both the field and herbarium. Six ISSR primers were used with 15 species, including 11 of Asimina, two of Deeringothamnus, one Annona and one Disepalum. AAgarose gels stained with ethidium bromide were used to determine the presence and absence of bands. These data were analyzed in PAUP using Neighbor Joining algorithms. Phenotypic characters (including morphology and floral scent chemistry) were included in addition to the molecular data. Deeringothamnus is strongly supported as being both a monophyletic group as well as being placed within the genus Asimina. The white-flowered and red-flowered species of Asimina split into two separate clades, albeit with less than 50% bootstrap support.
