Discussion of Phylogenetic Relationships

Of the different species in the genus Vahlkampfia listed by Page (1988) only two turned out to belong to the genus when the SSU rDNA was sequenced (Brown and De Jonckheeere 1999). A few recent isolates belong phylogenetically to the genus Vahlkampfia, i. e. V. signyensis (Garstecki et al. 2005), V. ciguana and V. orchilla (De Jonckheere 2006), and their cysts all look very similar (Fig.1).

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
