This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

Containing group: Stramenopiles


The class Bolidophyceae includes a single genus Bolidomonas and two species (Bolidomonas pacifica and B. mediterranea) described from marine waters.

The Bolidophyceae was established by Guillou et al. (1999), as a new class of picoplankton isolated from both the equatorial Pacific and the Mediterranean Sea. One genus, Bolidomonas, and two species, Bolidomonas pacifica and B. mediterranea, have been described. Guillou et al. also proposed a subspecies of B. pacifica: B. pacifica var. eleuthra.

Bolidomonas pacifica swims differently than B. mediterranea, and their flagella are oriented differently with respect to one another (Fig. 1). B. pacifica swims in a consistently straight pattern, and the flagella are oriented at a 90° angle with respect to one another. In contrast, B. mediterranea demonstrates frequent changes in swimming direction, and flagella are oriented at a 180° angle with respect to one another.

Relationship of Bolidophytes to other Stramenopiles

Phylogenetic analyses of nuclear 18S rRNA and plastid-encoded rbcL sequences indicate – with robust support – that Bolidomonas spp. are sister to the diatoms (Bacillariophyceae).

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.
